Problems solved by technology

[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 The impact of environmental conditions and agricultural measures, etc., the utilization rate of chemical fertilizers is very low

Abstract

Peanuts can grow well in soil which is loosened and soft, good in water retention property and rich in organic matter, according to the characteristic, multiple soil conditioners such as shell powder, kieselguhr and medical stone powder are compounded with organic fermentation substances to prepare a coating component of fertilizer granules, chemical minerals coated by a coating agent prepared from resin as a main component is used as an internal core, resin can be slowly degraded after entering a soil layer and thus a porous structure is formed to slowly release internal mineral elements, and then frequent fertilization can be avoided; peanuts need a great amount of water but being poor in water resistance, and the air permeability can be affected by waterlogging, so that fine-pore silica gel is added, then pulping can be implemented on one hand, on the other hand, moisture can be absorbed after the fine-pore silica gel enters the soil layer, the improved soil is loosened and is beneficial to expansion growth of peanuts, and the yield can be increased.

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 ...
