Abstract

The invention relates to agricultural biomass-sourced soilless culture selenium-enriched nutrient solution and a preparation method thereof. The nutrient solution takes biomass straw waste as a raw material and a selenium element source, smashing, enzymolysis and centrifugation are carried out to obtain biomass straw waste treating fluid, then the biomass straw waste treating fluid is mixed with mineral salt, amino acids, urea, folic acid, a compound growth regulator, oxidized glutathione and deionized water in a certain ratio, the mixed solution is stirred by utilizing a magnetic stirrer, then centrifugation is carried out, supernatant is taken, and finally dialysis is carried out by adopting a nanofilm, so that the filtered selenium-enriched nutrient solution is obtained. The obtained agricultural biomass-sourced soilless culture selenium-enriched nutrient solution not only can release natural plant active factors and promote root growth of crops but also can improve the immunity ofthe crops in resistance to plant diseases and insect pests, promote photosynthesis of the crops and improve the yield and the quality of the crops.

Description

technical field [0001] The invention relates to a nutrient solution and a preparation method thereof, in particular to a selenium-enriched nutrient solution for agricultural biomass source soilless cultivation and a preparation method thereof. Background technique [0002] Soilless cultivation is also called vegetative cultivation and hydroponics. It is a special cultivation method that does not use soil or manure when planting crops, and generally only uses chemical fertilizers or nutrient solutions made of chemical reagents to supply the nutrients needed by crops. Compared with traditional soil cultivation, soilless cultivation is less restricted by soil conditions, and at the same time, the labor intensity of production is low, which saves costs to a large extent. The water and fertilizer supply of nutrient solution cultivation generally adopts the micro-pipe irrigation system, which is easier to implement fixed-point and localization, and can significantly reduce the wa...
