Abstract

The invention discloses selenium fertilizer and vegetable soilless culture nutrient fertilizer comprising the selenium fertilizer, and belongs to the field of nutrient fertilizer. The selenium fertilizer is prepared from a selenium source and S-thioadenosylmethionine. The vegetable soilless culture nutrient fertilizer is prepared from macroelement fertilizer, trace element fertilizer and the selenium fertilizer. Plants are promoted to produce more methylated active selenium by adding a methyl donor to the soilless culture nutrient fertilizer, the methylated active selenium can be specificallyrecognized by a human body without causing toxicity, and the human body is safer and healthier. The selenium and the methyl donor are simultaneously used for providing a safer method of selenium for the human body, and meanwhile, a significant enhancement effect on plant growth is played. An optional method of program implementation is provided for crop fertilizer efficiency, soilless culture, plant factories and the like.

Description

technical field [0001] The invention relates to the field of nutrient fertilizers, in particular to a selenium fertilizer and a vegetable soilless cultivation nutrient fertilizer comprising the selenium fertilizer. The present invention is applicable to gardens, balconies, production seedbeds, demonstration gardens and plant factories for soilless cultivation of leafy vegetable cultivation and nutrition. Background technique [0002] Selenium is a beneficial element for plants and can promote the growth of plants. When selenium is applied to vegetables, it can increase the output value of vegetables and benefit the income of vegetable farmers. Vegetable selenium deficiency can cause selenium deficiency physiological diseases, such as cucumber selenium deficiency bending, Chinese cabbage selenium deficiency dry heartburn, etc., which seriously affect the quality and storability of agricultural products. [0003] Selenium is an essential element for humans. As a trace element...
