Problems solved by technology

The existing method of reducing the loss of chemical fertilizers is to slow down or control the release or decomposition of fertilizer nutrients through coating or urease inhibitors. However, due to the high cost of this chemical fertilizer, it can only be used in non-agricultural fields and cannot be used in agricultural production. universal application

Abstract

The invention belongs to the field of organic compound fertilizers and relates to a production method of a natural pumice loss-controlling organic compound fertilizer. The fertilizer in the prior art has serious loss, causes the environmental degradation and brings great harm to human beings. The production method has the following steps: taking raw material fertilizers of nitrogen, phosphorus and potassium, mixing with natural pumice powder which is smashed into 120 meshes and an organic fertilizer, uniformly stirring, preparing into mixed raw materials, then granulating, drying, screening, weighing and packaging. The weight of natural pumice in the fertilizer accounts for 10-30% of the total weight of the fertilizer; and the content of organic matters is 10-20%. The content of the nitrogen, the phosphorus and the potassium in the fertilizer is 20-40%. The production method has the advantages of simple production process and convenient use, and can control the nutrient loss, protect the ecological environment, reduce the fertilizer application cost, improve the utilization rate of the fertilizer, improve the physical and chemical properties of the soil and promote the stable and high yield of crops.

Description

technical field [0001] The invention belongs to an organic compound fertilizer; in particular, it relates to a natural pumice loss-controlling organic compound fertilizer and a production method thereof. Background technique [0002] Chemical fertilizers are called the "grain" of crops, but in recent years, the low utilization rate and serious loss of chemical fertilizers have led to environmental degradation, especially the deterioration of the water environment, which has brought great harm to human beings. Nitrogen is the main nutrient element of chemical fertilizers. At present, the nitrogen utilization rate of chemical fertilizers in my country is only 30% to 35%. Most of the nitrogen is lost due to runoff, leakage and volatilization, resulting in waste of energy and resources and damage to the environment. Part of the lost fertilizer flows into lakes, leading to eutrophication of the water body and frequent outbreaks of blue-green algae; the other part seeps into the g...
