Abstract

Disclosed is a fertilizer containing rich selenium and its preparing process, wherein the constituents include (by weight ratio): N 39.7-42.77, P 16.1-16.8, K 16.8-18.2, Se 1.0-1.9, Zn 1.9-2.98, Fe 2.4-2.8, Mg 0.9-0.96, Mn 1.4-1.58, Cu 1.2-1.44, Mo 0.08-0.09, B 1.48-1.58, Na 8.2-9.1, Ge 0.3-0.6, Ca 1.8-3.96 and V 0.5-1.1.

Description

technical field [0001] The invention relates to a method for preparing a fertilizer, in particular to a non-toxic selenium-rich fertilizer sprayed on leaves and a method for preparing the same, belonging to the field of fertilizers. technical background [0002] 72% of my country's land is deficient in selenium, and according to statistics, about hundreds of millions of people need to supplement selenium. Selenium is a very important element in the human body. If the human body is deficient in selenium, it will lead to a decrease in immunity, and it is easy to suffer from more than 40 diseases such as colds, liver diseases, cardiovascular diseases, and cancers. Northeast my country, North China, and Northwest China are areas lacking selenium in the soil. The soil lacks selenium. If people and animals eat agricultural products grown in this selenium-deficient soil, a series of diseases will occur, which will directly affect people's health. Life. In addition, in order to inc...
