Description
Agricultural humic acid is an organic substance formed mainly by the natural decomposition of the remains of plants and microorganisms. In agricultural production, humic acid is widely used to improve soil quality and enhance crop growth.
Product introduction：
Generally，the main function of agricultural humic acid is to promote the loam structure of the soil, improve soil aeration and water retention. It is able to improve the physical properties of soil by combining with minerals in the soil to form colloids. At the same time, the organic matter rich in humic acid can also provide nutrients for the soil, providing the energy and nutrients needed for crop growth.
In addition, agricultural humic acid also has the function of regulating soil pH. Soil pH has an important impact on plant growth, and overly acidic or alkaline soils may affect the development of plant roots and the inability to fully absorb nutrients. By adding humic acid, the acidity and alkalinity of the soil can be alleviated, so that the pH of the soil is within the range suitable for plant growth.
Otherwise, agricultural humic acid can also enhance the biological activity of soil. It can provide organic carbon source and energy for microorganisms such as bacteria, fungi, nematodes and other microorganisms in the soil, promote the reproduction and metabolic activities of microorganisms, thereby increasing soil fertility, improving soil structure and enhancing soil resistance.
In short, agricultural humic acid plays an extremely important role in agricultural production. By using humic acid rationally, we can improve the quality of the soil, increase the yield and quality of crops, reduce the cost of agricultural production and the risk of environmental pollution. Therefore, the development and use of humic acid as a new type of fertilizer for agricultural production will be an important development direction of agricultural production in the future.
The effect of humic acid on crop growth and development
Humic acid contains a variety of functional groups, activated humic acid becomes a high-efficiency bioactive substance, crop growth and development and physiological metabolism in the body has a stimulating effect, this characteristic is not available in general fertilizers, activated humic acid efficient bioactive substances according to a certain concentration of soaking, roots, dipping, spraying, watering, bottom fertilizer and other ways, have obvious stimulating effects on various crops. The comprehensive performance is the promotion of root development, and the good impact on crop yield and quality factors.
A. Early germination with high rate
The application of humic acid can accelerate seed germination and improve the seedling emergence rate, especially in early spring and low temperature (generally 1 ~ 3 days earlier germination, the emergence rate can be increased by 10 ~ 30%).
B. The root system is developed and the absorption is strong
Humic acid has a special role in promoting the root development of crops, many agricultural personnel call humic acid "root fertilizer", the impact on the root system is mainly manifested in, stimulate the division and growth of root meristem cells, so that the seedlings root quickly, secondary roots increase, root quantity increases, root elongation, and finally leads to the ability of crops to absorb water and nutrients is greatly enhanced.
C. Effects on the growth of aboveground vegetative bodies
On the basis of sufficient nutrient supply, the stimulating effect of humic acid can make the aboveground part of the plant grow vigorously. It is manifested in plant height, stem thickness, number of leaves, dry matter accumulation and other aspects.
D. Impact on yield and constituent factors
The yield and composition factors of humic acid on different crops are different. For grain crops, more ears, more grains, 1,000 grain weight, etc. play a role in increasing yield, and the early stage has good effects on tillering and reducing the empty straw rate.
