Abstract

The invention discloses a novel efficient biochar-based water-retaining dedicated crop fertilizer, prepared from, by weight, 100-300 parts of urea, 350-500 parts of monoammonium phosphate, 100-300 parts of potassium chloride, 0-15 parts of calcium magnesium phosphate fertilizer, 40-100 parts of biochar, 0-30 parts of EDTA (ethylene diamine tetraacetic acid) chelated trace elements, 0-15 parts of polyglutamic acid, and 0-100 parts of additives. The preparation process of the fertilizer is simple, the fertilizer contains biochar, polyglutamic acid and various trace nutrients and can improve soil environmental conditions, land utilization and land maintenance are combined, crop yield is increased, and the fertilizer has high efficiency and zero pollution.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a novel high-efficiency biochar-based water-retaining crop special fertilizer and a preparation method thereof. Background technique [0002] In the process of fertilizer application in my country, there are problems such as low fertilizer quality, excessive dosage, and improper application methods, resulting in low fertilizer utilization in my country. Statistics show that the return rate of fertilizers in my country is less than one-third of that of the United States and less than one-half of that of the world. The loss of a large amount of fertilizer nutrients not only causes waste of resources, but also brings a series of environmental problems. From the perspective of the current development of fertilizer technology, it is an effective way to solve some of the contradictions faced by current agricultural fertilization by improving the quality of fertilizers a...
