Novel mineral calcium magnesium phosphate and preparation method thereof

Abstract

The invention provides novel mineral calcium magnesium phosphate and a preparation method thereof. The novel mineral calcium magnesium phosphorus silicon dioxide is high in content and has a good cadmium reduction effect. With the novel mineral calcium magnesium phosphate and the preparation method thereof of the invention adopted, the cadmium reduction amplitude reaches up to 50%-70%; the cadmiumcontent of agricultural products can be reduced to be lower than the national standard; the yield and quality of the agricultural products are greatly improved; soil can be improved; and the PH valueof acid soil can be increased. The novel mineral calcium magnesium phosphorus silicon dioxide is high in content and has a good cadmium reduction effect; the cadmium reduction amplitude reaches up to50%-70%; the cadmium content of the agricultural products can be reduced to be lower than the national standard; the yield and quality of the agricultural products are greatly improved; the soil canbe improved; and the PH value of the acid soil can be increased.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a new mineral calcium magnesium phosphorus and a preparation method thereof. Background technique [0002] In the process of planting agricultural products, in order to increase the yield of agricultural products, it is often necessary to apply fertilizers to the agricultural products during planting. [0003] However, although the existing fertilizers can increase the output of agricultural products to a certain extent, the effect of increasing production is still not significant due to the small amount of trace elements contained in it, and the cadmium content of agricultural products far exceeds the national standard after maturity, thus making the agricultural products The quality is poor, and in addition, existing fertilizers tend to cause soil damage after application. Contents of the invention [0004] In view of this, the present invention ai...
