Abstract

The invention provides a soilless culture medium for selenium-enriched tomatoes. The soilless culture medium for the selenium-enriched tomatoes comprises the following components in parts by weight: 25-40 parts of river sand, 20-30 parts of a selenium-containing fermented product, 6-10 parts of yeast residues and 1-2 parts of mineral ash powder, wherein the selenium-containing fermented product is obtained by mixing and fermenting selenium dioxide, straw powder, bagasse, urea, brown sugar, sodium hydrogen carbonate, potassium dihydrogen phosphate, methionine and EM active bacteria in a weight ratio of (5-8):(8-12):(5-10):(1-3):(1-3):(5-8):(1-3):(6-10):(8-10). The soilless culture medium for the selenium-enriched tomatoes contains abundant nutrients and rich trace elements, is high in water retaining capacity and fertilizer retaining capacity, can effectively increase the total selenium content and the organic selenium content of tomato fruits, and can be widely applied to cultivation of the selenium-enriched tomatoes.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a soilless cultivation substrate for selenium-enriched tomato. Background technique [0002] Tomato is a vegetable with high nutritional value. It is rich in carotene, riboflavin, vitamin C, vitamin E and trace elements calcium, magnesium, iron, manganese, zinc, etc. It is rich in nutrition and has a special flavor. Raw food and cooked food can also be made into jam, which has the effects of losing weight, eliminating fatigue, increasing appetite, improving digestion of protein, and reducing bloating and food accumulation. It is deeply loved by people. [0003] Selenium is an essential trace element for the human body. Selenium is a multifunctional life nutrient element. Selenium has the functions of anti-cancer, protecting the heart, preventing Keshan disease and Kaschin-Beck disease, delaying aging, etc., and improving the body's immunity and disease resistance.
