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

The invention relates to an alkaline fertilizer. The fertilizer can be used for improving acid soil. Scientific research shows that a weakly alkaline human body is healthier, and most of plants and crops are suitable for growth in alkaline soil. Waste walnut shell and other waste materials are dipped, ground into homogenous pulp, and mixed with a microbial agent and weakly-alkaline modification agents such as gypsum powder and bone meal to prepare fertilizer outer enveloping components. The inside of the fertilizer comprises NPK nutrition components enveloped by an enveloping agent. The outer enveloping components firstly enter soil layers, loosen the soil, and improve gas permeability of soil, so that the inner enveloped components can easily enter the soil and directly act on roots, and are easy for absorption, and waste caused by rain washing is prevented. The specially prepared enveloping material has characteristics of slow release and no pollution. The fertilizer makes agricultural products healthier.

Description

technical field [0001] The invention relates to an alkaline ecological functional fertilizer and a preparation method thereof, belonging to the technological field of alkaline functional components 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 seasonal utilization rate of fertiliz...
