Abstract

The invention relates to an oligosaccharide-containing soilless culture liquid fertilizer. The weight percentage of the oligosaccharide in the liquid fertilizer accounts for 0.2-4%, the weight percentage of the inorganic fertilizer accounts for 50-90%, the weight percentage of the antiseptic bactericidal substance accounts for 0-30%, the weight percentage of the algae removal substance accounts for 0-1%, and the balance of water, wherein the oligosaccharide can be selected from chitosan oligosaccharide, sodium alginate oligosaccharide, pectin oligosaccharide, isomalto-oligosaccharide, xylo-oligosaccharide and soybean oligosaccharide, and the inorganic fertilizer can be selected from more than two of the elements including nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, iron, manganese, copper, zinc and molybdenum. Due to the reasonable proportion of the oligosaccharides, inorganic fertilizer, antiseptic bactericidal substance and algae removal substance, the oligosaccharide-containing soilless culture liquid fertilizer can improve the quality of the crops in all aspects.

Description

technical field [0001] The invention relates to a liquid fertilizer for soilless cultivation, more particularly to a liquid fertilizer for soilless cultivation containing oligosaccharides. Background technique [0002] In recent years, the area of ​​cultivated land in our country has been decreasing year by year, and the production of vegetables and flowers has gradually become specialized and large-scale. In particular, the area of ​​cultivated areas in protected areas has been expanding year by year. It is difficult to further promote and apply the reasonable land rotation system. Soil pests and diseases caused by repeated cropping of land are becoming more and more serious. The soilless cultivation method can effectively prevent the occurrence of soil-borne diseases. As long as the seeds, medium, equipment, nutrient solution, etc. are strictly sterilized and managed properly, it is generally not easy to be infected by diseases and insect pests. Because the soilless culti...
