Abstract

The invention discloses a nutrient solution for soilless hydroponic vegetables. The nutrient solution is prepared from a composite bacterium agent, composite elements and auxiliary additives; the composite bacterium agent is prepared from nocardioform actinomycetes, bacillus subtilis, silicate bacteria and rhodopseudomonas palustris, the composite elements comprise ligninase, spirulina powder, ammonium sulfate, calcium superphosphate, potassum fulvic acid, ammonium nitro-humate, dicyandiamide, ferrous sulfate and sodium silicate, and the auxiliary additives comprise EDTA chelate manganese, L-amino acid and active peptide. The nutrient solution for the soilless hydroponic vegetables can enhance fertility of water by being dissolved into water for cultivating vegetables, flowers and fruits and can also serve as foliage fertilizer which is dissolved into water and sprayed to plants, roots or leaf surfaces of the plants are not burnt, and the nutrient solution has the advantages of being mild in fertility, lasting in fertilizer effect and green and environmentally friendly.

Description

technical field [0001] The invention relates to a nutrient solution for soilless hydroponic vegetables and a preparation method thereof. Background technique [0002] Soilless cultivation is the technology of cultivating plants completely with nutrient solution without soil, which is a major innovation in human planting methods. Soilless cultivation not only grows fast, has high yield and good quality, but also liberates human planting activities from the shackles of the soil, opening up broad prospects for the realization of industrialization and automation of agricultural and horticultural production. Soilless cultivation is to cultivate crops without natural soil, but to cultivate crops in nutrient solution, which can replace natural soil to provide water, nutrients, oxygen, and temperature to crops, so that crops can grow normally and complete their entire life cycle. Nutrient solution is the key to soilless cultivation, and different crops require different nutrient so...
