Biological bacterium-containing highly nutritional disease prevention nitrogen fertilizer

Abstract

The invention relates to a biological bacterium-containing highly nutritional disease prevention nitrogen fertilizer, which comprises the following technical proportion scheme: 0.1-1% of DA-6, 0.2-1% of sodium nitrophenolate, 0.5-2% of bacillus subtilis, 0.5-2% of bacillus licheniformis, and more than or equal to 95 % of urea. The biological bacterium-containing active multi-microelement fertilizer overcomes the defects of the existing fertilizer, the utilization rate of the fertilizer is improved, the application amount of the fertilizer is reduced, the cost is reduced, the yield improvement effect is obvious, and meanwhile, the environmental pollution is reduced, the soil is activated, the uptake and utilization of crops for organic fertilizers are improved, and the objects of yield improvement, synergy, environmental protection and cost reduction are achieved.

Description

[0001] Field [0002] The invention belongs to agricultural fertilizers, in particular to a high-nutrition and disease-preventing nitrogen fertilizer containing biological bacteria. technical background [0003] With the growth of population, the development of industry and the continuous expansion of urban scale, a large amount of arable land is occupied, and the area of ​​arable land is shrinking year by year. In order to meet people's demand for food and agricultural by-products, it is necessary to increase food production, and the application of chemical fertilizers is to increase food production. effective means. At present, traditional chemical fertilizers such as: nitrate nitrogen fertilizer, ammonia nitrogen fertilizer, amide nitrogen fertilizer, etc., all have a certain effect on increasing production. Because this kind of chemical fertilizer is volatile quickly and has low utilization rate, if you want to increase production, you need to apply more, which is invisibl...

AI Technical Summary

Problems solved by technology

At present, traditional chemical fertilizers such as: nitrate nitrogen fertilizer, ammonia nitrogen fertilizer, amide nitrogen fertilizer, etc., all have a certain effect on increasing production. Because this kind of chemical fertilizer is volatile quickly and has low utilization rate, if you want to increase production, you need to apply more, which is invisible to farmers. It increases the burden, and at the same time, a large number of long-term use also brings many side effects, such as: pollution to the environment, groundwater and rivers and lakes are polluted to varying degrees through the infiltration of rainwater, which makes the soil harden and destroys the air permeability of the soil.
