Controlled-release fertilizer for planting towel gourd and preparation method of controlled-release fertilizer

Abstract

According to the invention, high-fiber organic materials such as sawdust, waste paper and humus are adopted as basic materials and fermented to be used as a base fertilizer so as to improve soil for a root system of towel gourd, the towel gourd belongs to a vegetable planted in hole soil, and the soil quality and nutrients near the root system play an important role in the quality and yield of towel gourd; fermented sawdust, humus and leaves have thermal-insulation effects, so that the survival of towel gourd seedlings is facilitated, the towel gourd seedlings are protected from the frost damage caused by cold spell in spring, and survival rates of the seedlings is improved; and meanwhile, nitrogen, phosphorus and potassium components are added by virtue of coating in resin, nutrients are slowly released during the degradation process of the resin, and the degradation speed of the resin can be controlled and regulated by changing concentrations of the resin and the crosslinking agent so as to achieve the purpose of controlled release, which is very important in subsequent fertilizer and water management.

Description

technical field [0001] The invention relates to a loofah planting controlled-release fertilizer and a preparation method thereof, belonging to the technical field of loofah planting slow-release 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 seasonal utilization rate of fertilizers is...
