Phosphatic fertilizer for spore plant

Abstract

The invention provides a phosphatic fertilizer for a spore plant. The phosphatic fertilizer comprises the following components in percentage by weight: 2 to 8 percent of bacillus cereus, 2 to 8 percent of bacillus licheniformis, 2 to 8 percent of bacillus mucilaginosus, 2 to 8 percent of polyaspartic acid, 20 to 30 percent of potassium metaphosphate, 25 to 35 percent of monoammonium phosphate, 7 to 15 percent of diammonium phosphate and 10 to 20 percent of double superphosphate. Spores generated by bacilli are used for activating mineralized phosphorus elements and potassium elements in soil,and phosphorus elements and potassium elements which are easily absorbed and used by the plant are released, so that the utilization efficiency of the fertilizer is improved, and the yield of crops and the quality of agricultural products are improved at the same time.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizers, in particular to a spore plant phosphate fertilizer added with beneficial microorganisms. Background technique [0002] my country is a country with a large population, accounting for a quarter of the world's total population. Food security has been the top priority of successive governments. However, with the continuous advancement of industrialization and urbanization, the area of ​​cultivated land has been shrinking year by year, and the problem of food security has become more and more prominent. To meet people's demand for food and agricultural by-products, it is necessary to increase the output of food and agricultural by-products.

Problems solved by technology

The application of chemical fertilizers is an effective means to increase grain yield per unit area. However, due to the fact that traditional phosphate fertilizers are easily formed into insoluble phosphates after being applied to the soil, and are quickly fixed by soil minerals, their utilization rate in the current season is less than 25%. According to estimates from the national soil census, Two-thirds of the soil in my country is deficient in phosphorus. The main reason for the deficiency of phosphorus is that the available phosphorus content in the soil is insufficient, and a large amount of phosphorus applied to the soil is stored in the soil in an ineffective state.

Due to the lack of phosphorus in the soil and the low utilization rate of phosphorus fertilizers, the substantial increase in grain production is always accompanied by a large amount of phosphorus fertilizer input, which not only causes a waste of limited phosphorus fertilizer resources, but also inevitably leads to the increase of phosphorus concentration in the runoff, resulting in the enrichment of water bodies.
