Soil phosphorus activator and manufacturing method thereof

Abstract

The invention relates to a technique for regulating soil nutrient elements and a technique for treating and handling solid waste, in particular to a soil phosphorus activator and a manufacturing method thereof, which solves the problems that farmland soil is low in phosphorus effectiveness and fertilizer phosphorus is rapidly fixed after entering the soil. According to dry weight ratio, the activator comprises 35 to 45 portions of vitamin C fermentation waste residue, 35 to 45 portions of lignite, 3 to 5 portions of sawdust, 3 to 5 portions of natural zeolite powder, 10 to 14 portions of coal cinder. The manufacturing method comprises the steps of mixing the Vc fermentation waste residue with the lignite and the sawdust, retting the mixture for 3 to 5 days at a normal temperature, adding the coal cinder to the mixture, composting the mixture for 4 to 6 days at a medium temperature, air-drying and sifting the mixture, adding the natural zeolite powder to the mixture, evenly mixing and separately packaging the obtained product and obtaining a finished product. The soil phosphorus activator has the advantages that the activator is friendly to environment, simple in process and low in cost, and can be applied to farmland alone or be mixed with chemical fertilizer for application.

Description

technical field [0001] The invention relates to soil nutrient element control technology and solid waste treatment and disposal technology, in particular to a soil phosphorus activator and a preparation method thereof. Background technique [0002] Phosphorus is an important nutrient element to maintain the long-term stability of the structure and function of agricultural ecosystems. However, on a global scale, phosphorus resources have become a scarce resource, and the world's phosphorus fertilizer prices have been rising in the last ten years, and the rate of increase shows a trend of increasing year by year. China is rich in phosphate rock resources, but the rich ore is relatively small, and the reserves owned by the available phosphate rock areas only account for about 11% of the total resources. According to statistics, during the 10 years from 1994 to 2004, 8 large and medium-sized phosphate mines were exhausted; from 1999 to 2001, nearly 90 new phosphate mines were b...
