Abstract

The invention relates to the field of liquid fertilizer, in particular to liquid fertilizer for water culture of cucumber. The liquid fertilizer is prepared from raw materials as follows: sodium acetate, sodium carbonate, sodium thiosulfate, sodium chloride, magnesium sulfate, urea phosphate, potassium chloride, yeast extract, water and photosynthetic bacterial suspensions. The liquid fertilizer has the advantages that the selected strain is high in purity, the microecology of effective viable bacteria is stable, the bacterial metabolite is exuberant and the like, and can significantly increase the growth rate of the cucumber, increase the seedling biomass, promote the development of young roots, reduce the diseases, effectively decompose allelo-chemicals secreted by cucumber roots and increase the yield.

Description

technical field [0001] The invention relates to the field of liquid fertilizer. In particular, it relates to a hydroponic cucumber liquid fertilizer. Background technique [0002] Cucumber is one of the vegetable varieties with the largest planting area in greenhouses, and damping-off, damping-off, and root retting frequently occur in hydroponic cultivation. This is mainly because the phenolic allelochemicals in the root exudates can have adverse effects on cucumber plants through various channels, and the nutrient solution itself does not have the ability to purify, and the cell residues shed by the plants and the carbon dioxide produced by rhizosphere respiration cannot be decomposed , leading to further deterioration of the nutrient solution environment, abnormal pH, and the growth of bacteria. The nutrient solution needs to be replaced regularly during planting, which leads to increased planting costs. In addition, due to the presence of a large amount of plant rhizos...
