Fertilizer used for selenium-enriched paddy rice and preparation method thereof

Abstract

The invention discloses a fertilizer used for selenium-enriched paddy rice and a preparation method thereof, which belong to the field of paddy rice plantation. The fertilizer has the advantages that the environment is not polluted, soil is effectively improved, the incidence rate of the paddy rice insect disease is low, and the fertilizer efficiency is strong. The fertilizer comprises the following components in parts by weight: 15-20 parts of cottonseed cake, 15 parts of rapeseeds, 13 parts of bagasse, 5 parts of cassava powder, 0.4 parts of bio fungus, 13 parts of urea, 55-59 parts of calcium superphosphate, 17-22 parts of potassium chloride, 1-2 parts of zinc phosphate, 1-2 parts of inorganic selenium salt, and 1 part of diatomite. The fertilizer can be used for selenium-enriched paddy rice.

Description

technical field [0001] The invention belongs to the field of selenium-enriched rice planting, in particular to a special fertilizer for selenium-enriched rice and a preparation method thereof. Background technique [0002] Selenium is an indispensable trace element in the human body. Selenium and vitamin E are both anti-peroxidation substances (peroxides are harmful to the human body). It has also been proved that it has a therapeutic effect on children who are malnourished due to lack of protein. Carcinogens are resistant. The main manifestations of selenium deficiency in the human body are hair loss and nail loss. Some patients have skin symptoms, and a small number of patients may have neurological symptoms and tooth damage. People with mild or moderate selenium deficiency have no obvious signs or symptoms. Possible diseases caused by selenium deficiency in human body: energy deficiency malnutrition, hemolytic anemia, Keshan disease, Kashin-Beck disease, hypertension, i...

AI Technical Summary

Problems solved by technology

Most of the existing selenium-enriched rice is sprayed with selenium-containing inorganic salt on the rice leaf surface at the early stage of rice flowering and flowering. In this way of foliar spraying, it is difficult for all selenium elements to be absorbed, and the selenium-enriched effect cannot be achieved.
