Selenium-enriched earthworm organic leaf fertilizer

Abstract

The invention provides a production method of selenium-enriched earthworm organic leaf fertilizer. The production method of the selenium-enriched earthworm organic leaf fertilizer comprises the following steps: diluting hypertoxic inorganic selenium into a certain proportion, uniformly spraying the diluted hypertoxic inorganic selenium on fermented dry cow dung, adding earthworm cocoons in a certain density, harvesting once a clitellum appears on the earthworms, cleaning the harvested earthworms, spraying water and weighing, adding white sugar and red sugar in a certain proportion, and naturally decomposing; and adding fermentation liquor in proportion, sealing and fermenting, thus obtaining the selenium-enriched earthworm organic leaf fertilizer. The production method of the selenium-enriched earthworm organic leaf fertilizer has the advantages that hypertoxic inorganic selenium is introduced into the earthworms, then is absorbed and utilized by the earthworms and participates in metabolism, and thus inorganic selenium is converted into organic selenium; the earthworms rich in organic selenium are naturally decomposed by utilizing a saccharification technology, and thus nutritional ingredients of organic selenium and the earthworms are reserved and utilized to the utmost extent; then fermentation is carried out by utilizing a biotechnology, and thus the selenium-enriched organic leaf fertilizer is obtained; the production method of the selenium-enriched earthworm organic leaf fertilizer is simple and practicable, effect is good, and after the selenium-enriched earthworm organic leaf fertilizer is diluted to a certain proportion and applied to pear trees for 3-4 times in different periods, crisp pears rich in selenium element can be produced.

Description

technical field [0001] The invention relates to a selenium-enriched fruit foliage fertilizer, in particular to a selenium-enriched earthworm organic foliar fertilizer for pear spraying. Background technique [0002] Selenium has various functions such as anti-cancer and anti-cancer, degrading heavy metals in the human body, delaying aging, preventing and treating diabetes, etc. It has been recognized by the world's medical circles as early as the 1970s. 72% of China is in the state of selenium deficiency or low selenium. Insufficient selenium intake in the diet seriously affects the health of hundreds of millions of people. Therefore, people pay more and more attention to supplementing selenium properly through eating fruits. However, the methods commonly used in recent years are mostly to directly spray the highly toxic sodium selenite on the growing fruit trees after dilution. Although this method is simple, it can also meet the requirements of selenium supplementation an...
