High-potassium green manure

Abstract

The invention relates to a high-potassium green manure, belonging to the composite fertilizer containing nitrogen, phosphorus, potassium, cellulose and other multiple elements. The high-potassium green manure is mainly prepared from wheat straw and chemical raw materials by fermenting, acidifying and securing and contains three elements required by the growth of crops. The tests show that the high-potassium green manure contains 38% of potassium, 10.9% of phosphorus and 12.86% of nitrogen. The high-potassium green manure is superior to the 37% compound fertilizer in the domestic industry, can be applied to a variety of crops, contains a large amounts of cellulose and changes the existing defect of applying fertilizer to the soil. After being applied, the high-potassium green manure can be directly absorbed by the crops without being subjected to chemical reaction and can take effect on the barren soil most quickly in two days. The potassium acid in the high-potassium green manure can well inhibit the viruses in the soil. In addition, the high-potassium green manure is simple in production process, is easy to operate and can resist the three insects, thereby being a novel composite fertilizer in the domestic fertilizer industry.

Description

technical field [0001] The invention discloses a high-potassium green manure, in particular a compound fertilizer containing nitrogen, phosphorus, potassium and cellulose. Background technique [0002] At present, the fertilizers commonly used in the vast rural areas of our country include nitrogen fertilizer, urea, phosphorus fertilizer, and farmyard manure. Long-term monotonous use of a certain chemical fertilizer will cause the land to lack nitrogen, phosphorus, and potassium, and the land will become severely flattened. The price of chemical fertilizers is also high, increasing land crops. The cost makes it difficult for farmers to buy; the use of farmyard manure alone is insufficient in fertilizer efficiency, and the majority of farmers are eager to have a multi-element compound fertilizer with high fertilizer efficiency and low price. Contents of the invention [0003] The purpose of the invention is to provide a compound fertilizer containing nitrogen, phosphorus, p...
