Hydroponic culture solution for vegetables

Abstract

The invention discloses a hydroponic culture solution for vegetables, belonging to the technical field of soilless culture of plants. The hydroponic culture solution comprises 40 to 46 parts of soybean fermentation extract, 30 to 34 parts of radix angelicae sinensis leachate, 20 to 26 parts of seaweed meal, 10 to 14 parts of bacillus thuringiensis powder, 9 to 13 parts of yeast powder, 1 to 3 parts of vitamin C, 0.3 to 0.9 part of nitric acid, 0.09 to 0.15 part of ammonium molybdate and 300 to 400 parts of deionized water. The hydroponic culture solution for vegetables is wide in action rangeand comprehensive in nutritional ingredients, has self-purification and self-regulation effects, and is remarkable in yield increasing effect. According to the invention, the performance indexes of Chinese chives, garlic and spinach are high, plant height meets required requirements, a compact plant type is realized, the plot yield of the Chinese chives is 41.68 kg / mu to 42.02 kg / mu, the plot yield of the garlic is 1201.71 kg / mu to 1202.18 kg / mu, the plot yield of the spinach is 2391.0 kg / mu to 2393.1 kg / mu, and economic benefits are remarkable.

Description

technical field [0001] The invention belongs to the technical field of plant soilless cultivation, and in particular relates to a vegetable hydroponic culture solution. Background technique [0002] Hydroponic vegetables refer to vegetables whose roots grow in layers of nutrient solution and only provide water, nutrients, and oxygen through nutrient solution, which is different from traditional soil cultivation. Hydroponic vegetables have a short growth cycle and are rich in a variety of vitamins and minerals necessary for the human body. Hydroponics is a kind of soilless cultivation, which is classified into substrate-free cultivation. The substrate-free cultivation type refers to the environment in which the roots of plants grow without a substrate to fix the roots. The roots grow in nutrient solutions or moist air containing nutrient solutions, but when raising seedlings Certain substrates may be used. [0003] According to the existing literature search, it is found th...

Problems solved by technology

[0003] According to the existing literature search, it is found that the Chinese Patent Publication No. CN107311783A, the patent application published on November 3, 2017, discloses a bioactive nutrient solution for hydroponic vegetables. The combination of liquid and live probiotics for aquatic products has played a certain role in promoting the growth of vegetables in the process of vegetable hydroponics, but its effect is not obvious enough, the scope of action is narrow, the nutritional components are not comprehensive, and it does not have self-purification and self-regulation effect
