An efficient peanut planting slow-release fertilizer and a preparing method thereof

Abstract

Soil which is soft, good in water retention and rich in organic matters is suitable for peanut planting. According to the characteristic, a plurality of soil improving agents, such as shell powder, diatomite and Chinese medical stone powder, are compounded with organic fermented matters and then adopted as a coating component of fertilizer particles, chemical mineral components coated with a coating agent prepared mainly from resin are adopted as an inner core, and the resin slowly degrades to form a porous structure and to slowly release the inner mineral elements after the resin enters soil layers, thus avoiding frequent fertilizing. Peanut needs water, but is not water-tolerant, and waterlogging influences permeability, and therefore fine-hole silica gel is added, and the fine-hole silica gel can be used for pump grinding, and can absorb water vapor after entering soil layers. Improved soil is loose, and is beneficial to peanut expanding and growing, thus increasing the yield.

Description

technical field [0001] The invention relates to a high-efficiency slow-release fertilizer for peanut planting and a preparation method thereof, belonging to the technical field of slow-release functional fertilizer for peanut planting in fertilizers. Background technique [0002] Chemical fertilizer is the largest material input in agricultural production. According to the statistics of the Food and Agriculture Organization of the United Nations, chemical fertilizers account for 40-60% of the increase in yield. However, the production time shows that due to the nature of the fertilizer itself and the soil Due to the impact of environmental conditions and agricultural measures, the utilization rate of chemical fertilizers is very low. The waste of nutrient resources caused by the low utilization rate of fertilizer nutrients in China is astonishing. According to statistics, the annual production and application of nitrogen fertilizer in China is about 20 million tons, and the ...
