Problems solved by technology

Although my country is the country with the largest number of fertilizer manufacturers in the world, most of them are small and medium-sized chemical fertilizer enterprises. There are not many varieties and enterprises that can compete with imported compound fertilizers in product quality and effect, and there are fewer products suitable for green agricultural production.

Abstract

The invention relates to a water-soluble compound fertilizer for activating soil and realizing no-tillage and a preparation method for the water-soluble compound. The water-soluble compound fertilizer is prepared from the following raw materials in percentage by weight: 15 percent of urea, 50 percent of monopotassium phosphate, 25 percent of humic acid and 10 percent of bacillus subtilis microbial inoculum. The preparation method comprises the following steps of: 1) crushing the urea; 2) culturing the bacillus subtilis microbial inoculum; 3) sequentially adding urea powder, the humic acid and the monopotassium phosphate into a continuous reaction kettle; 4) adding the bacillus subtilis microbial inoculum and performing secondary blending; and 5) packaging and warehousing. The invention has the advantages that: the fertilizer has quick action and long action, and can directly provide nutrition for crops and activate immobilized nutrition in the soil, activate the soil and inhibit bacteria in the soil, increase the yield and improve the quality, promote the development of root systems and improve the water and fertilizer retention capacity of soil, and effectively increase soil fertility and reduce the using amount of chemical fertilizers; and the water solubility of the product is over 98 percent, and the product is applied together with water or injected into the soil by using a fertilizing gun, is simple, convenient and easy, and is labor-saving and cost-saving.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and in particular relates to an activated soil, no-tillage water-soluble compound fertilizer and a preparation method thereof. Background technique [0002] my country is one of the countries with the least cultivated land per capita, so protecting the ecological environment and improving soil fertility have particularly important strategic significance. my country is currently focusing on the implementation of the fertile soil project plan, which emphasizes the application of organic fertilizers and the combined use of organic fertilizers and chemical fertilizers to reduce blind input of chemical fertilizers and improve nutrient use efficiency. Although my country is the country with the largest number of fertilizer manufacturers in the world, most of them are small and medium-sized chemical fertilizer enterprises. There are not many varieties and enterprises that can compete with importe...
