Abstract

The invention provides a biological compound potash fertilizer and a preparation method of the biological compound potash fertilizer. The biological compound potash fertilizer is prepared by the following steps of: fermenting pathogenic fungus CGMCC (China General Microbiological Culture Collection Center) No.5155 which resists 12.5% of potash and has chitinase activity to obtain a biological potash fertilizer; and mixing 8-15 parts of the biological potash fertilizer, 1-5 parts of dipotassium phosphate and 10-15 parts of humic acid potash fertilizer to prepare the biological compound potash fertilizer. The biological compound potash fertilizer provided by the invention is simple in preparation method, strong in product compositionality and strong in parataxis and has the functions of evenly providing nutrients, improving soil fertility, strengthening the stress resistance of crops, decreasing the crop diseases, improving the quality of agricultural products, decreasing the harmful substances in the agricultural products and the like.

Description

technical field [0001] The invention belongs to the field of fertilizers, and relates to a biological compound potassium fertilizer and a preparation method thereof. Background technique [0002] Fertilizer production and technology development are not only the core issues of agricultural production, but also related to the environment, ecology and the survival and development of human society. China is one of the largest potash fertilizer consumption countries in the world, and its potash fertilizer consumption accounts for about 20% of the world's potash fertilizer consumption. Domestic potassium fertilizer consumption is increasing year by year, with an average annual consumption growth rate of 12%. China's potash fertilizer can only meet about 30% of the domestic potash fertilizer demand, and about 5-6 million tons of potash fertilizer needs to be imported every year. With the promotion of domestic balanced fertilization technology and the adjustment of planting struct...
