Fruit-vegetable selenium-enriched compound fertilizer

Abstract

The invention discloses fruit-vegetable selenium-enriched compound fertilizer, which is prepared from the following components in parts by weight: 200 to 240 parts of a mixture of chicken manure, duck manure and sheep manure, 50 to 70 parts of a mixture of sweet potato leaf and lettuce leaf, 30 to 50 parts of floating aquatic plant dry powder, 5 to 15 parts of clam shell powder, 20 to 30 parts of urea, 15 to 25 parts of sodium selenite, 4 to 6 parts of manganese sulfate, 5 to 7 parts of zinc sulfate, 3 to 5 parts of magnesium sulfate, 5 to 7 parts of phosphate rock powder, 3 to 5 parts of culture and 18 to 22 parts of potassium humate. According to the fruit-vegetable selenium-enriched compound fertilizer, through adding poultry-livestock manures and plant fibers, overall nutrients are provided for the growth of a crop; the sodium selenite is applied to the selenium-enriched fertilizer; the threats of the fertilizer self to the health of a producer and a consumer are evaded. Meanwhile, fermentation is carried out on the plant fibers and the poultry-livestock manures by adopting the culture; organic compounds of high molecular protein and the like in the plant fibers and the poultry-livestock manures are decomposed; the organic compounds are degraded into nutritional ingredients which are suitably absorbed by a plant; the absorption factor of the crop to a nutritional substance can be improved.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a selenium-enriched compound fertilizer for fruits and vegetables. 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 eleme...
