As natural biological stimulants and organic chelating agents for trace elements, amino acids can promote recovery from abiotic or biotic stress.
Amino acid foliar fertilizer is mainly applied with amino acids and is compounded with trace fertilizer. They contain nutrient growth regulators and essential trace elements for plants. Amino acid foliar fertilizer can be understood as a foliar fertilizer containing amino acid active factors.
Crops can absorb compound amino acid foliar fertilizer through leaves, stems, or roots of the plants. It has effective functions in rooting, germination, healthy seedlings, flower promotion, fruit growth, and fruit protection of crops. Moreover, it can stimulate the activity of enzymes, improve the photosynthetic efficiency, increase the absorption and operation of nutrients, increase the content of chlorophyll and sugar, increase the accumulation of dry matter, improve the quality of crops, and enhance drought resistance, disease resistance, stress resistance, and immunity of crops.
Non-toxic and harmless
There are many domestic field experiments and demonstrations that show that amino acid foliar fertilizer can promote root growth, healthy seedlings, and vigorous plants, and enhance the 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. Meanwhile, there is the role of improving product quality.
Amino acid foliar fertilizer can be used in many plants. It is not only suitable for wheat, cotton, soybean, peanut, rapeseed, beet, and tobacco but also suitable for vegetables, fruit trees, tea trees, flowers, etc. Amino acid foliar fertilizer is mainly used for extra-root spraying, it can also be used for seed soaking, seed dressing, roots, irrigation roots, and so on.
Humic acids have many plant protection functions, it solve the problem of the rapid development of large-area orchards and new value-preserving challenges faced by facility agriculture. It has its unique advantages and it shows in the following five aspects:
1. Improve the defense of plants against natural disasters
After the utilization of humic acids, the root system is mainly developed, the biochemical action of chlorophyll is enhanced, the metabolism is healthy, and the disease resistance is strong. The recovery from drought, locust plague, and freezing disease are very obvious. When the plants suffered catastrophic abrasion, it was used by bacteria. The utilization of humic acid can repair the abrasion of the plants quickly to avoid bacterial infection and fruit loss. As for planting, immerse the seedlings in water for 30 minutes with humic acid 300 times, seedlings survival rate increased more than 30%.
2. Fertilization and disease prevention
Some researchers have applied biological humic acid in disease prevention and treatment. Humic acids are believed that contain high physiological activity and particular live bacteria. Humic acid has the function of healthy moisture absorption, it can adjust the flora of soil microorganisms. The structure and diversity inhibit the indigenous pathogens in the soil and enhance crop variability. Applying organic humic acid in an early time can adjust the ecology 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 wide utilization of chemical fertilizers, pesticides, and hormones, and the misuse of fertilizers, fruit trees have premature aging and even fruit orchard withering. This is called "chemical pesticide syndrome." The application of 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
Humic acid trace element liquid fertilizer's effective function of "hormone supplement", disease prevention, and yield increase is obvious. It is the advantage of organic humic acid. Nowadays, a variety of fruit trees use fruit bagging. If spray humic acid liquid fertilizer before bagging, the fruit will grow full, bright, and sweeter, and it is real green food.
5. Overcoming barriers in the greenhouse
The barriers to continuous cropping in greenhouses are due to the abnormal changes in the microbial ecosystem and fertilizer factors in the soil environment after the regular multi-season cultivation in greenhouses, which leads to the abnormal growth of crops and hinders continuous cropping. It has been 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 used better with EM bacteria, they can supplement the microfluid needed by crops and are easily absorbed. These elements can overcome the obstacles of continuous cropping in the greenhouse well, and even win good harvests.
The seaweed fertilizer's raw material is seaweed, through technical means breaks down the seaweed cells and releases the content. The seaweed is then concentrated to form a seaweed concentrate, which significantly retains the natural active ingredients of the seaweed. It is a new fertilizer that has high efficiency and low cost.
The characteristics of seaweed fertilizer are as follow:
1. Nutrient-rich
The active seaweed fertilizer contains a large amount of non-nitrogen-containing organic matter, including potassium, calcium, magnesium, iron, zinc, iodine, etc 40 kinds of minerals, and abundant vitamins that terrestrial plants are incomparable, 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
After the active ingredients have been specially treated, the active ingredients in seaweed fertilizers are particularly active. Within 2 to 3 hours after application, they enter the plants and have a speedy absorption and conduction velocity. The alginic acid in seaweed fertilizer can reduce the surface tension of water, forming a layer of film on the surface of the plant so that increasing the contact area, and the water-soluble substances are relatively easy to penetrate the surface cells of stems and leaves, and the plants can effectively absorb the nutrients in the seaweed extract.
3. Improve the soil
Seaweed fertilizer belongs to a natural biological system that can work in harmony with the plant-soil ecosystem. It can increase soil organic matter through soil or plants directly and activate various microorganisms in the soil. During the circulation of plant-microbial metabolites, these microorganisms can act as catalysts, increasing the biological effectiveness of the soil.
4. Fertilizer effect special long
Seaweed fertilizer can increase soil organic matter directly through the soil or plants, and activate various beneficial microorganisms which can act as catalysts in the circulation of plant-microbial metabolites and increase the biological efficiency of the soil. The 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 raw material of seaweed fertilizer is derived from natural seaweeds, it has a good affinity with terrestrial plants, and it is not only non-toxic and harmless to humans and livestock but also has no pollution to the environment. Seaweed fertilizers are high-quality fertilizers for the production of safe vegetables.
The application of compound microbial fertilizers on crops can improve the effective utilization of chemical fertilizers and also can enhance the usage of fertilizers.
1. Total Nutrition
It provides crops with necessary NPK and trace elements and also gives crops organic and beneficial microbial active bacteria.
2. Effect of slow-release and improves the fertilizer utilization
During the process of production, there are some inorganic nutrients are dissolved and chelated together by the organic matter to form an organic NPK. The soil is fixed and not easily lost. It increases the utilization rate of chemical fertilizer by 10-30%, and the fertilizer efficiency can last 3-4 times. Month.
3. Loose the soil, dissolve phosphorus and potassium and fertility
When the fertilizer enters the soil, the organic matter, inorganic nutrients, moisture, and temperature can help the microorganisms multiply, which reduces the living space of the harmful microbial population and increases the number of useful microbial bacteria in the soil. Microbial bacteria can produce large amounts of organic acids. The phosphorus and potassium elements that are deposited in the soil for many years are partially dissolved and released, and they can be reabsorption by the crop. Use it for l long time later, 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 multiply. They secrete quantities of chitinase, extracellular enzymes, and antibiotics, which can effectively lyse the spore walls of harmful fungi, and 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 healthy seedlings, reducing nitrite content, improving quality, increasing production and income
After the microorganisms multiply in the soil, they produce a large amount of plant hormones and organic acids, stimulate the growth and development of roots, enhance the photosynthetic intensity of plants, and make the plants grow deep and leafy, which can effectively increase the sugar content of crop fruits, reduce nitrates, and other products in plant 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 the soil
It can not only provide organic nutrients for crop growth, and improve the resistance of crops, but also can reduce the survival of some pathogenic bacteria in the soil.
Chitosan and its derivatives can be used as plant growth regulators, seed coating agents, foliar sprays, moisturizers, insecticides, fungicides, feed additives, and soil amendments in agriculture. Chitosan and its derivatives have been widely used in agriculture due to the function of improving quality, inducing broad-spectrum disease resistance in plants, and so on.
Application
Applying chitosan 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 combined with other fungicides, it can inhibit the occurrence of the disease. The incidence is reduced by 30% to 50% compared with the control group.
The soybean germination rate and germination potential were increased after the seeds were coated with chitosan. It can promote the hair root, nodulation, and the growth of the underground after seed sowing, moreover, it can improve the protein synthesis of seedling leaves, and increase the photosynthetic rate;
As for corn seeds, treating them with aqueous methylol-chitosan (NCMC) solution can promote seed germination, increase the germination rate, and germination vigor. Treating maize ear with NCMC aqueous solution can increase the soluble protein of immature maize kernels and increase the maturity of mature seeds. Storage protein content.
Moreover, experiments were conducted on cotton, rice, and vegetables(potatoes, cabbage, and cucumbers). All results showed that chitosan and its derivatives had achieved excellent results in terms of promoting crop yield and improving quality. Research demonstrated that chitosan and its derivatives promote the increase of glutamine synthetase, lead to the enhancement of nitrogen metabolic pathways, and correspondingly increase the protein synthesis so that the storage protein in seeds is also significantly improved.
Chitosan and its derivatives have very large prospects for development and application because of their obvious advantages compared with other growth regulators, such as natural, non-toxic, odorless, excellent environmental compatibility, high activity, and natural degradation.
