Abstract

The invention discloses a selenium-rich biological fertilizer which is prepared from the following components in parts by weight: 50-60 parts of pig manure, 30-40 parts of cow dung, 20-40 parts of buckwheat straw, 4-6 parts of corn straw, 5-10 parts of seaweed meal, 4-6 parts of selenium-rich matter, 1-2 parts of lime powder, 5-7 parts of manganese sulfate, 3-5 parts of calcium sulphate, 1-3 parts of sodium selenite, 5-7 parts of bacteria strain and 20-30 parts of potassium humate. According to the invention, the animal dung and the plant fiber are added for supplying comprehensive nutrition to the crop growth. The bacteria strain is adopted for fermenting the plant fiber and the animal dung, degrading the organic compounds, such as, macromolecule protein therein, decomposing the organic compounds into the nutritional ingredients easily absorbed by the plant, so that the absorption rate of the crop for the nutrition is increased.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a selenium-enriched biological fertilizer. Background technique [0002] Selenium (Se) is a trace element with a molecular weight of 78.96. It is located in the VIA group of the chemical element periodic table, and its chemical properties are similar to the sulfur element of the same group. The current general view is that an appropriate amount of selenium in the diet plays an important role in maintaining the health of the human body. First of all, selenium plays an irreplaceable role in improving the body's antioxidant capacity. In addition, selenium also has important physiological functions such as anti-cancer, liver protection, binding heavy metals, and prevention and treatment of cardiovascular diseases. At the same time, selenium deficiency is also an important cause of human Kashin-Beck disease and Keshan disease. As an important trace element, selenium plays an im...
