Problems solved by technology

[0002] Soilless cultivation is inseparable from the nutrient solution, and a series of equipment is required to match the preparation of the nutrient solution, such as testing systems, circulation pumps, etc., and if it is an open cultivation technology, there will be high nitrate content in the waste nutrient solution, which will easily cause water body enrichment after discharge. The danger of nutrition; if it is a closed cultivation technique, the existence of a large amount of organic matter in the nutrient solution is easy to breed pathogenic bacteria, which brings the risk of devastating damage to the crops, and the closed system requires corresponding disinfection equipment, which further increases the investment burden.

Abstract

The invention discloses a composite microbial preparation nutrient solution for soilless culture of plants. The composite microbial preparation nutrient solution is an efficient composite microbial bacterial solution prepared from single strains such as bifidobacteria, bacillus subtilis, photosynthetic bacteria, bacillus megatherium, azotobacter brown and lactobacillus bulgaricus through a special process. The total beneficial bacteria count in each milliliter is greater than or equal to 20 billion CFU. The method comprises the steps of: sequentially adding the mixed bacterial liquid, the fructo-oligosaccharide, the radix salviae miltiorrhizae, the soybean meal, the bran, the wheat germ, the glucose, the table salt and the softened water into a fermentation tank according to the proportion; and fermenting, cooling, re-fermenting, discharging bacterial liquid, and packaging to obtain a finished product. The method can be widely applied to vegetables, flower and tree bonsai, flower and fish co-culture, medicinal materials, vermiculite culture, ceramsite and the like. Compared with the prior art, the method has the advantages of simplicity, energy conservation, low cost and high benefit.
