For the purpose of absorbing the foliage, the nutrient required by the crop is directly applied to the foliar fertilizer, which is called an amino acid foliar fertilizer.
Amino acid-containing foliar fertilizers are mainly applied with amino acids, and are compounded with trace fertilizers. They contain plant nutrient growth regulators and trace elements necessary for plants. Amino acid foliar fertilizer can be simply understood as a foliar fertilizer containing amino acid active factors.
Compound amino acid foliar fertilizer is absorbed by crops through the leaves, stems or roots of crops. It has a significant effect on rooting, germination, strong seedlings, flower promotion, fruit growth and fruit protection of crops, and can stimulate enzyme activity, increase photosynthetic efficiency, and accelerate Nutrient absorption and operation, increase of chlorophyll content, increase of dry matter accumulation and sugar content, improvement of crop quality, enhancement of crop drought resistance, disease resistance, stress resistance, and immunity.
Amino acid fertilizer is non-toxic and harmless
After many domestic field experiments and demonstrations, amino acid foliar fertilizer can promote root growth, strong seedlings, strong plants, enhanced photosynthetic function of leaves and crop resistance. The ability to resist diseases and insect pests has a significant effect on the production of various crops. At the same time, there is the role of improving product quality.
Amino acid foliar fertilizer is suitable for wheat, cotton, soybean, peanut, rapeseed, beet, tobacco and various vegetables, fruit trees, tea trees, flowers, etc. Amino acid foliar fertilizer is mainly used for extra-root spraying, and can also be used for seed soaking and seed dressing,roots, irrigation roots and so on.
1. Amino acids, which are the smallest molecules that make up proteins, are found in fertilizers and are easily absorbed by crops. They also have the function of improving the resistance of fertilized objects and improving the quality of fertilized crops.
2. Supplement the essential amino acids of plants, stimulate and regulate the rapid growth of plants, promote plant growth and promote the absorption of nutrients. To enhance the metabolic function of plants, increase photosynthesis, promote the development of plant roots, and accelerate plant growth and reproduction.
After many experiments with multiple crops, it has been shown that amino acid organic leaf fertilizer can significantly increase the yield of crops, and can effectively increase the soluble sugar content, reduce the NO3-content, and increase the absorption and utilization of nitrogen, phosphorus, and potassium.
Humic acid has many functions in plant protection and solves the problems of rapid development of large-area orchards and the new value-preserving problems faced by facility agriculture. It has its unique advantages. Humic acid manifests itself in the following five aspects:
1 Improve the defense of plants against natural disasters.
After the use of humic acid, the root system is particularly developed, the biochemical action of chlorophyll is enhanced, the metabolism is strong, and the disease resistance is strong. The drought, locust plague, and freezing disaster recovery are very obvious. After the catastrophic abrasion, it is used by bacteria. The application of humic acid to the plant quickly repairs the abrasion of the plant and avoids fruit loss due to bacterial infection. In terms of planting, the seedlings were immersed in water for 30 min with humic acid 300 times, and the survival rate of seedlings increased.
More than 30%.
2 Fertilization and disease prevention.
A number of researchers have applied biological humic acid to prevent and treat diseases. It is believed that humic acid not only has high physiological activity, but also contains special live bacteria. Humic acid has strong moisture absorption function and adjusts the flora of soil microorganisms. Structure and diversity, inhibiting indigenous pathogens in the soil, enhance crop variability. The earlier application of biological humic acid is conducive to the timely ecological adjustment of soil microorganisms, change soil compaction, fertilizer efficiency and control effect is more obvious.
3 Treatment of Weak Strain of Fruit Tree by Mineral Source Humic Acid.
Due to the large number of chemical fertilizers, pesticides and hormones, and the application of fertilizers, fertilizers are used improperly to cause fat wounds, and fruit trees have premature aging and even fruit orchard withering. This is called “chemical pesticide syndrome.” With humic acid concentrated liquid fertilizer, combined with organic fertilizer, loose soil, root cutting, appropriate pruning and other agricultural techniques can be fully rejuvenated.
4 Foliage spraying on crops.
The effect of humic acid trace element liquid fertilizer on the “supplementing hormone” and disease prevention and yield increase of crops is obvious. This is the advantage of biological humic acid. Now a variety of fruit trees use fruit bagging. If humic acid liquid fertilizer is sprayed before bagging, The fruit will grow very full, bright appearance, taste more sweet, is a real green food.
5 Overcoming barriers in the greenhouse.
Continuous cropping barriers in greenhouses are caused by abnormal changes in the microbial ecosystem and fertilizer factors in the soil environment in greenhouses after normal multi-season cultivation, which results in the inability of crops to grow normally, and continuous cropping is hindered. Facts have proved that the use of humic acid trace element liquid fertilizer can restore the biodiversity of cultivated soil in the greenhouse and form a good ecological environment. If it is better to use with EM bacteria, they can supplement the micro-fluid needed for crops and can be easily absorbed. The elements can well overcome the obstacles to continuous cropping in greenhouses, and they have even won a good harvest.
The seaweed fertilizer uses seaweed as a raw material to break down the seaweed cells and release the contents through technical means. The seaweed concentrate is then concentrated to form a seaweed concentrate, which greatly retains the natural active ingredients of the seaweed. It is a highly efficient and low-cost new fertilizer.
The characteristics of seaweed fertilizer are as follows:
The active seaweed fertilizer contains a large amount of non-nitrogen-containing organic matter, including 40 kinds of minerals such as potassium, calcium, magnesium, iron, zinc, and iodine, and abundant vitamins, which are unmatched by terrestrial plants, especially seaweed polysaccharides unique to seaweeds. Alginic acid, highly unsaturated fatty acids and a variety of natural plant growth regulators can stimulate the production of non-specific active factors in plants and regulate the balance of endogenous elements.
2 Easily absorbed by plants
The active ingredients in seaweed fertilizers are particularly active after they have been specially treated, and they enter the plants within 2 to 3 hours after application, and they have a very fast absorption and conduction velocity. Alginic acid in seaweed fertilizer can reduce the surface tension of water, forming a layer of film on the surface of the plant, increasing the contact area, water-soluble substances are relatively easy to penetrate the surface cells of stems and leaves, so that plants can effectively absorb the nutrients in the seaweed extract. ingredient.
3 Improve the soil
Seaweed fertilizer is a natural biological system that works in harmony with the plant-soil ecosystem. It can directly increase soil organic matter through soil or through plants and activate various microorganisms in the soil. These microorganisms can act as catalysts in the circulation of plant-microbial metabolites, increasing the biological effectiveness of the soil.
4 Fertilizer effect special long
Seaweed fertilizer can directly increase soil organic matter through the soil or through plants, and activate various beneficial microorganisms in the soil. These microorganisms can act as catalysts in the circulation of plant-microbial metabolites and increase the biological efficiency of the soil. Metabolites of plants and soil microorganisms can provide more nutrients to plants. At the same time, the chelation system formed by seaweed polysaccharides and humic acid can release nutrients slowly and extend fertilizer efficiency.
5 Safe and non-toxic
The seaweed fertilizer raw materials are derived from natural seaweeds, have good affinity with terrestrial plants, are non-toxic and harmless to humans and livestock, and have no pollution to the environment. They are high-quality fertilizers for the production of harmless vegetables.
The application of compound microbial fertilizers on crops can not only improve the effective utilization of chemical fertilizers, but also improve the utilization of fertilizers.
From 10% to 30%, application tests showed that the use of composite microbial fertilizers produced by Bacillus spores for more than two years continuously increased the number of beneficial actinomycetes in the soil by 8.4 times and nitrogen-fixing bacteria increased by 39 times, thereby reaching the soil for activation and planting. , To increase the role of soil fertility, the beneficial propagation of beneficial microorganisms, and to activate and reuse chemical fertilizers that have been fixed in the soil for many years. At the same time, the increase in the number of Bacillus spores in the soil can effectively prevent and control soil-borne fungi and root-knot nematodes. The control rate can reach as high as 70-80%, which is equivalent to that of chemical pesticides. In order to reduce the use of chemical pesticides, improve the quality and yield of crops and the ability to resist heavy smashing.
Functional features of compound microbial fertilizer
1 Total Nutrition
Not only provides the necessary NPK and trace elements for crop growth, but also provides crops with organic and beneficial microbial active bacteria.
2 Fertilizer has the effect of slow release and improves the utilization of fertilizer
In the production process, some of the inorganic nutrients are dissolved and chelated together by the organic matter to form an organic NPK. The soil is not easily lost and fixed. The utilization rate of chemical fertilizers can be increased by 10-30%, and the fertilizer efficiency can last 3-4 times. month.
3 Loose the soil, dissolve phosphorus and potassium and fertility
After the fertilizer enters the soil, the microorganisms multiply with the help of organic matter, inorganic nutrients, moisture, and temperature, which reduces the living space of the harmful microbial population, thereby increasing the number of useful microbial bacteria in the soil. The microbial bacteria can produce large amounts of organic acids. The phosphorus and potassium elements deposited in the soil for many years are partially dissolved and released for reabsorption by the crop. After long-term use, the soil will become looser and more fertile.
4 Disease prevention and pest control
The microbial bacteria are dormant in the fertilizer and enter the soil to germinate and reproduce. They secrete a large amount of chitinase, extracellular enzymes and antibiotics, which can effectively lyse the spore walls of harmful fungi, the nematode egg wall and inhibit the growth of harmful bacteria. Effectively control the occurrence of soil-borne diseases and pests, and play the role of disease prevention, pest control and anti-double stress.
5 Rooting strong seedlings, reducing nitrite content, improving quality, increasing production and income
After the microorganisms reproduce in the soil, they produce a large number of plant hormones and organic acids, stimulate the growth and development of roots, enhance the photosynthetic intensity of crops, and the crops grow deep and leafy, which can effectively increase the sugar content of crop fruits and reduce nitrates and other products in crop products. The content of harmful substances can improve the quality of crops and increase the yield by 10-30%.
6 Accelerate the degradation of organic matter in soil
Not only to provide more organic nutrients for crop growth, improve the resistance of crops; also can reduce the survival of some pathogenic bacteria in the soil.
Chitosan is a natural polymer straight-chain polysaccharide after deacetylation of chitin, and chitin is obtained from the treatment of shrimp and crab shells with acid and alkali. Chitosan and its derivatives are mainly used in textile printing and dyeing, papermaking, photography, heavy metal recycling and wastewater treatment, but later focused on biomedicine, food and other fields.
It has been reported abroad years ago that chitosan and its derivatives can be used as regulators of plant growth, seed coating agents, foliar sprays, moisturizers, insecticides, fungicides, feed additives, and soil amendments in agriculture. Agent. Since chitosan and its derivatives have been used in agriculture to increase production, improve quality, induce broad-spectrum disease resistance of plants, and so on, they have attracted widespread attention from abroad and some promising research results have been obtained.
Research on the use of chitosan in agriculture started relatively late in China, but it has also achieved significant results. For example, applying it to wheat seed dressing can promote tillering, increase the number of effective panicles, and increase production by 10.9% to 22.5% compared with the control group. If used in combination with other fungicides, it can inhibit the occurrence of the disease, the incidence of which is reduced by 30% to 50% compared with the control group;
After the soybean seeds were coated with chitosan, their germination rate and germination potential were increased. After seed sowing, it can promote the hair root, nodulation and the growth of the underground, can promote the protein synthesis of seedling leaves, and increase the photosynthetic rate;
Treating corn seeds with aqueous methylol-chitosan (NCMC) solution can promote seed germination, increase germination rate and germination vigor. Treating maize ear with NCMC aqueous solution can increase the soluble protein of maize immature kernels and increase the maturity of mature seeds. Storage protein content.
In addition, experiments were conducted on cotton, rice, and vegetables such as potatoes, cabbage, and cucumbers. The results all showed that chitosan and its derivatives have achieved remarkable results in terms of promoting crop yield and improving quality. . Studies have shown that chitosan and its derivatives promote the increase of glutamine synthetase, which leads to the enhancement of nitrogen metabolic pathways, and correspondingly increase the protein synthesis, so that the storage protein in seeds is also significantly improved. In addition, glutamate dehydrogenase exists in various tissues of plants, and its catalyzed reaction is one of the most important ways that ammonia nitrogen enters organic compounds to form amino acids. Experiments show that chitosan and its derivatives can increase the activity of glutamate dehydrogenase. Therefore, chitosan and its derivatives also have certain regulatory functions on the nitrogen metabolism of crops.
It is worth noting that the best results are not the same with chitosan and its derivatives treated in different ways (soaking, coating, spraying, etc.). The test results also show that chitosan and its derivatives have obvious concentration effects on the yield and quality of crops, ie there is an optimal concentration range. In addition, the chitosans or derivatives thereof prepared by the general method are different in both the homogeneity of the molecules and the plasticity of the film formation, and therefore, the test results also produce a large difference. Therefore, for chitosan and The preparation of its derivatives, only through a more rigorous production process can get more ideal results.
Since chitosan and its derivatives have obvious advantages compared with other growth regulators, such as natural, non-toxic, odorless, good environmental compatibility, high activity, and easy degradation, they have very large The development prospects can therefore become the current research hotspot.
