Slow-release fertile having insecticidal function special for lawn and preparing process thereof

Abstract

The invention provides a slow-release fertile having insecticidal function special for lawn and a preparing process thereof. According to the weight percentage, the fertile contains 30% to 60% of peat soil substrate, 10% to 30% of tea seed extraction, 2% to 15% of coagulant, 0.5% to 10% of binder and 2% to 15% of chemical manure, wherein the coagulant is silicate; the binder is polyving akohol; and the chemical manure contains urea, potassium phosphate and magnesium sulfate. The preparing process comprises the steps of uniformly mixing the peat soil substrate, the tea seed extraction and the silicate, adding polyving akohol into the mixture, putting into a grinder, stirring, airing in the room till the water content is 60%, adding into the chemical manure, grinding, pressing and airing so as to obtain the finished product.

Description

technical field [0001] The invention relates to the technical field of chemical industry, and specifically refers to a slow-release fertilizer for lawn maintenance with both nutrition and insecticidal functions. Background technique [0002] In recent years, the turf industry in my country has developed very rapidly, but what follows is the management and protection of turfgrass. At present, there are two major problems to be solved: one is the application of chemical fertilizers on turfgrass, and the other is the problem of pest control on turfgrass. In the management of lawn, frequent watering is easy to cause the loss of fertilizer and reduce the utilization rate of fertilizer. In addition, fertilizer components flowing into rivers and lakes can directly lead to eutrophication of water bodies, causing algae to overgrow and water quality to deteriorate; infiltrating into the ground, causing large areas of groundwater to exceed the standard of nitrate nitrogen, causing ser...

AI Technical Summary

Problems solved by technology

At present, there are two major problems that need to be solved: one is the application of chemical fertilizers on turfgrass, and the other is the problem of pest control on turfgrass.

At present, slow-release fertilizers are developing rapidly in some developed countries, but the development speed in my country is still relatively slow. From the perspective of environmental protection and convenient management, it is important to develop environmentally friendly slow-release fertilizers for lawns that have both nutritional and insecticidal functions. significance
