Abstract

The invention provides a preparation method of a nutritional liquid for seedling of vegetables. The preparation method comprises the following steps of a, mixing straws, fruit peels and algae, and forming powder by ball milling; b, mixing a composite additive, potassium sulfate, calcium chloride, manganese sulfate and boric acid, guiding into a mixing machine, stirring, and dispersing by ultrasonic waves, so as to obtain a material I; c, adding the powder, a nitrogen-fixing bacteria mixed solution, a nitrogen source matter, candida polysaccharides, distilled water, lactobacillus and protease into the material I to ferment, so as to obtain a fermented liquid; d, adding a traditional Chinese medicine extracting solution, trace elements and compound amino acid into the fermented liquid, stirring, filtering, and concentrating filtrate. The prepared nutritional liquid contains a large amount of nutritional matters and physiological active matters; the protein, amino acids, vitamins and flavonoids can be absorbed by vegetables after fermenting, so that the quick seedling and growth of the vegetables are promoted; for the fruited vegetables, the flowering and fruiting cycle can be shortened.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a preparation method of a nutrient solution for raising vegetable seedlings. Background technique [0002] In traditional vegetable planting, due to the intensive production of the soil year after year, large-scale application of chemical fertilizers and pesticides, and frequent rainwater leaching, the chemical residues in the soil are high and the effective fertilizer efficiency is reduced, resulting in a serious imbalance in the soil ecology, resulting in the production of vegetables. Low quality, poor quality, serious physiological diseases. Moreover, the current traditional production mode has disadvantages such as cumbersome management, heavy labor, low land use efficiency, and poor economic benefits. [0003] Soilless cultivation uses peat or forest leaf humus, vermiculite and other light materials as the seedling substrate to fix the plants, allo...
