Slow control release biological inorganic and organic mixed fertilizer

Abstract

The invention belongs to the field of agriculture, which relates to a slow control release biological inorganic and organic mixed fertilizer. The mixing fertilizer is prepared by fully mixing the following components in percentage by weight: 3%-10% of beneficial microbial agent, 0.4%-1% of fertilizer slow control release agent, 5%-12% of organic matter, 0.2%-10% of plant growth stimulin, 15%-25% of nitrogen, 5%-12% of phosphorus, 6%-15% of potassium, and 2%-10% of middle trace element. The invention not only has the advantages of high nutrient concentration and simple production process, but also can enhance the utilization rate of the fertilizer, save the fertilizer, increase the output, improve the soil, and promote the sustainable development of agriculture and environment protection.

Description

technical field [0001] The invention relates to a slow-controlled release bio-organic-inorganic blend fertilizer in the field of agriculture. technical background [0002] In recent years, the blended fertilizers used for crops have developed rapidly. China is a big agricultural country and also a big country in the use of chemical fertilizers. For decades, my country's chemical fertilizer industry has developed rapidly, but the utilization rate of chemical fertilizers is very low. The utilization rate of nitrogen fertilizer in my country is only 35%-45%. The utilization rate of phosphate fertilizer is only 10%-25%. A considerable amount of fertilizer is lost into the groundwater and the atmosphere, polluting the environment. On the other hand, due to the low utilization rate of fertilizer, farmers have increased the use of chemical fertilizers in order to increase production. According to statistics, the total amount of chemical fertilizers used in our country has leapt to th...

[0002] In recent years, the blended fertilizers used for crops have developed rapidly. China is a big agricultural country and also a big country in the use of chemical fertilizers. For decades, my country's chemical fertilizer industry has developed rapidly, but the utilization rate of chemical fertilizers is very low. The utilization rate of nitrogen fertilizer in my country is only 35%-45%. The utilization rate of phosphate fertilizer is only 10%-25%. A considerable amount of fertilizer is lost into the groundwater and the atmosphere, polluting the environment. On the other hand, due to the low utilization rate of fertilizer, farmers have increased the use of chemical fertilizers in order to increase production. According to statistics, the total amount of chemical fertilizers used in our country has leapt to the first place in the world. The result of using a large amount of chemical fertilizers is to aggravate environmental pollution and decline in soil fertility. According to the survey, the degradation of black soil in our country is relatively serious. The main reason is that farmers are predatory. The planting only pursues high yield and does not cultivate the land, resulting in soil compaction, a decrease in organic matter content, and a decrease in the buffering capacity, water storage and fertilizer storage capacity of the soil.
