Therefore, how to ensure the production of pollution-free vegetables, So as to meet the needs of people’s life as soon as possible? It has become a concern and urgent problem for agricultural technology popularizers. The application of humic acid products in vegetable production will play a positive role in solving the above problems.
Effect of humic acid products in the production of pollution-free vegetables.
The application of humic acid products can improve the utilization rate of fertilizer.
The vegetable is a high-fertilizer crop, and the fertilizer amount is larger than that of the large field crop. So that the use of the fertilizer in a certain range has a remarkable effect on the growth, yield and quality of the vegetables. But excessive application, not only the fertilizer efficiency is reduced, the economic waste is caused, but also the soil structure can be destroyed. So that the soil is hardened and the environment is polluted.The excessive application of the nitrogen fertilizer has resulted in the excessive accumulation of nitrate nitrogen in the vegetables in many areas and the serious pollution of the ground water and the soil. The fertilizer utilization rate is low. The fertilizer efficiency is reduced. And the fertilization habit of the heavy inorganic fertilizer and the light organic fertilizer has become a major obstacle to the production of the pollution-free vegetables.The potassium humate has the effects of quick-acting and yield-increasing of general chemical fertilizers. The functions of activating soil, slow-release and fertilizing of the organic fertilizer, harmless and no pollution. And a great significance for solving the contradiction of developing agriculture and protecting the environment, and promoting the ecological circle of the ecological environment.
The application of fulvic acid can reduce the amount of pesticide application and reduce the pesticide residue in vegetable products.
Inhibitory effect of fulvic acid on plant pathogens
Effect of Fulvic Acid on Pesticides
The release efficiency of the fulvic acid on the pesticide can be increased. The dosage of the pesticide can be reduced.The fulvic acid can be used as a non-toxic and pollution-free substance. Not only can be used as a pesticide alone, but also can be mixed with a pesticide. The composite of humic acid , organic and inorganic phosphorus pesticide can greatly reduce the decomposition rate of the organic phosphorus. Due to the fact that the humic acid molecules contain more hydrophilic groups and are mixed with the pesticide, the fulvic acid molecules can effectively play the good dispersing and emulsifying action. Thereby contribut to the improvement of the pesticide activity.
In addition, the fulvic acid has a large internal surface area. Has a strong adsorption effect on the organic inorganic matters. Compatible with the pesticide. Therefore, a complex with high stability can be formed. So that the pesticide has lasting stability. The fulvic acid and the pesticide composite can reduce the dosage of the pesticide by 1/3-1/2. The pesticide effect is delayed for 3-7 days. And the toxicity of the fulvic acid and the pesticide is greatly reduced. Which is of great significance for reducing the environmental pollution and developing the pollution-free vegetable production.
