Abstract

The invention provides stable fertilizer inhibiting greenhouse gas release. The stable fertilizer comprises a core material and an envelopment bonding material coated on the surface of the core material, wherein the core material comprises the following ingredients: nitrogen containing substance, phosphorus containing substance, potassium containing substance and stabilization substance. A preparation technology of the stable fertilizer comprises the following steps of: 1) uniformly mixing and pelleting the nitrogen containing substance, the phosphorus containing substance, the potassium containing substance and the stabilization substance, and 2) preparing the envelopment bonding material into envelopment solution for envelopment. The invention provides a scientific and reasonable fertilizer formula, and the fertilizer can achieve double effects of fertilizer reduction and efficiency increase of a vegetable field and emission reduction of nitrous oxide greenhouse gas when the fertilizer is applied. In addition, a preparation technology of the fertilizer is simple, practicable, mature and perfect.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a stable fertilizer that suppresses the release of greenhouse gases and a preparation process thereof. Background technique [0002] The greenhouse effect, also known as the "greenhouse effect", is a common name for the atmospheric heat preservation effect. The atmosphere can make the sun's short-wave radiation reach the ground, but the large amount of long-wave heat radiation emitted by the surface after being heated is absorbed by the atmosphere, so that the effect of the surface and lower atmospheric temperatures is similar to that of a greenhouse for cultivating crops, hence the name greenhouse effect. [0003] The greenhouse effect is extremely harmful to the environment. It can lead to a series of problems such as global warming, increased pests and diseases, increased sea level, abnormal climate, land desertification, and reduced oxygen content, and has far-reaching effects on a...
