What is the difference between amino acid and humic acid ?
In recent years, with the development of agricultural science and technology, the state's attention to agriculture and the importance of safe and efficient agriculture of agricultural products, a brand-new term "biostimulant" has been put forward in the industry. Today, we will not explore the definition and scope of biostimulants, but simply popularize several common fertilizer products that have a certain effect on crops on the market.
Amino acid foliar fertilizer is a soluble foliar spraying fertilizer containing amino acid nutrients. Amino acid is one of the more important nutrient elements in the process of crop growth. It is very helpful to the photosynthetic respiration of plants, and can improve the content of chlorophyll and the quality of crops.
The rational application of foliar fertilizer containing amino acids is mainly amino acids and complex micro fertilizer, which contains plant nutritional growth regulators and essential trace elements. Amino acid foliar fertilizer can be simply understood as foliar fertilizer containing amino acid active factors.
Compound amino acid foliar fertilizer is absorbed by crops through crop leaves, stems or roots. It has obvious effects on crop rooting, germination, seedling strengthening, flower promotion, fruit strengthening and fruit preservation. It can stimulate enzyme activity, improve photosynthetic efficiency, accelerate nutrient absorption and operation, increase chlorophyll content, improve dry matter accumulation and sugar content, improve crop quality, and enhance crop drought resistance, disease resistance, stress resistance and immunity.
Amino acid fertilizer is non-toxic, pollution-free and does not pollute the environment
Through the domestic multi-point field experiment and demonstration, amino acid foliar fertilizer can promote the growth of roots, strengthen seedlings and plants, enhance the photosynthetic function of leaves and the stress resistance of crops. It has the ability of disease and insect resistance, and has a significant yield increasing effect on a variety of crops. At the same time, it also plays a role in improving product quality.
Amino acid foliar fertilizer is suitable for wheat, cotton, soybean, peanut, rape, sugar beet, tobacco, various vegetables, fruit trees, tea trees, flowers, etc. amino acid foliar fertilizer is mainly used for spraying outside the root, but also for soaking seeds, dressing seeds, dipping roots, irrigation roots, etc.
Functions and advantages of amino acid foliar fertilizer:
1. Amino acids, as the smallest molecule of protein, exist in fertilizer and are easy to be absorbed by crops; It can also improve the disease resistance of fertilized objects and improve the quality of fertilized crops.
2. Supplement the essential amino acids of plants, stimulate and regulate the rapid growth of plants, promote the healthy growth of plants and promote the absorption of nutrients. Enhance the metabolic function of plants, improve photosynthesis, promote the development of plant roots, and accelerate plant growth and reproduction.
Many experiments on many crops show that amino acid organic foliar fertilizer can significantly improve crop yield, effectively improve the content of soluble sugar, reduce the content of NO3 - and improve the absorption and utilization of nitrogen, phosphorus and potassium.
Humic acid foliar fertilizer is a kind of soluble foliar spraying fertilizer containing humic acid. Humic acid is a kind of organic matter in nature, which is mainly transformed from animal and plant corruption and decomposition. Now it is widely used in fertilizer and can improve the soil environment.
Humic acid has many functions in plant protection, and solves the new problems faced by the rapid development of large-area orchards and facility agriculture. It has its unique advantages. Humic acid is reflected in the following five aspects:
1. Improve plant defense against natural disasters.
After the use of humic acid, the root system is particularly developed, the biochemical effect of chlorophyll is strengthened, the metabolism is prosperous, and the disease resistance is strong. It is very obvious in the recovery of drought, waterlogging and freezing. When the scratch after the disaster is infected by bacteria, it is sprayed with humic acid solution, and the plant scratch is repaired quickly to avoid fruit loss due to bacterial infection. In terms of planting, the survival rate of seedlings was increased by more than 30% by soaking the roots and seedlings with 300 times of sea elf humic acid for 30 minutes.
2. Fertilization and disease prevention.
Some researchers have done a lot of research on the application of biological humic acid fertilizer for disease prevention. They believe that humic acid not only has high physiological activity, but also contains special living bacteria. The hygroscopic function of humic acid is very strong, which adjusts the flora structure and diversity of soil microorganisms, inhibits native pathogens in soil and enhances the variability of crops. Earlier application of biological humic acid is conducive to the timely ecological adjustment of soil microorganisms, change soil hardening, and more obvious fertilizer and control effects.
3. Treatment of diseased and weak trees of fruit trees with mineral derived humic acid.
Due to the rapid application of chemical fertilizers, pesticides and hormones and the fertilizer injury caused by improper use of chemical fertilizers, the phenomenon of premature aging of fruit trees and even withering of orchards occurs, which is called "chemical pesticide syndrome". With humic acid concentrated liquid fertilizer, combined with organic fertilizer, loosening soil and cutting roots, appropriate pruning and other agricultural measures, we can completely rejuvenate.
4. Spray the leaves of crops.
The foliar spraying of humic acid trace element liquid fertilizer has obvious effect on crop "element supplement" and disease prevention and yield increase, which is the advantage of biological humic acid. Now many fruit trees use fruit bagging. If humic acid liquid fertilizer is sprayed before bagging, the fruit will grow plump, bright appearance and sweeter taste. It is a genuine green food.
5. Overcome the obstacles of greenhouse serialization.
The obstacle of continuous cropping in greenhouse is that after multi-season cultivation, the abnormal changes of microbiota and fertilizer factors in the soil environment in greenhouse lead to the failure of normal growth of crops and the obstruction of continuous cropping. 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 used together with EM bacteria, the effect will be better. They can supplement the trace elements required by crops and easy to be absorbed, overcome the obstacles of continuous cropping in the greenhouse and achieve bumper harvests.
Four similarities and differences between amino acid leaf fertilizer and humic acid
[structural differentiation]: the composition diagram of 20 basic amino acids is as follows:
The structure of humic acid is complex, as shown in the following figure:
[type differentiation]: amino acid foliar fertilizer is a water-soluble organic-inorganic compound (chelating) fertilizer. It is a multi chelating production process of trace elements. The higher the chelating value, the better the absorption and utilization rate of crops. For example, the absorption and utilization rate of high-efficiency molar foliar fertilizer is more than 95%, which is very beneficial to the peak period of fertilizer demand in the middle and later stages of crops and the crops that need to be hypertrophic. After spraying for a week, it can significantly expand fruits, color, promote early maturity, improve quality and other benefits.
Humic acid foliar fertilizer and organic-inorganic compound (chelating) water-soluble fertilizer are more favorable to the phenomenon of soil hardening and fertility decline caused by the long-term use of chemical fertilizer in the farmland, with more topdressing but no increase in yield. They can quickly adjust the soil structure and loosen the soil, so that the nutrients in the soil can be better absorbed by plants.
[distinguishing features]: amino acid foliar fertilizer is a fatty acid containing nitrogen, with small molecular weight
Humic acid leaf fertilizer is macromolecular aromatic organic carboxylic acid.
[function differentiation]: amino acid foliar fertilizer is characterized by significantly improving the applied nutrients, better and faster absorption, transformation and utilization, and significantly improving the stress growth and disease resistance of increased crops.
Humic acid leaf fertilizer can quickly and effectively activate the soil, effectively adjust the soil pH and balance the pH. it is a pollution-free green ecological fertilizer. In addition, it can promote the physiological metabolism of crops, improve photosynthesis, increase the fruit rate and single fruit weight, prolong the fresh-keeping period, picking period, prevent flower and fruit falling, prevent various diseases and insect pests, prevent various diseases and insect pests, and effectively alleviate the diseases caused by pesticides and herbicides.
