Soilless culture nutrient solution

Abstract

The invention belongs to the field of gardening, and in particular relates to a soilless culture nutrient solution. The nutrient solution is prepared from the following components: 680-1200mg / L of calcium nitrate, 520-885mg / L of potassium nitrate, 460-780mg / L of ferrous nitrate, 255-400mg / L of magnesium sulfate, 100-150mg / L of a disinfectant, 9-14mg / L of a plant hormone and 300-700mL / L of hydrogen peroxide, wherein the solvent is water; the disinfectant can prevent plants from being infected by viruses and bacteria and producing disease; the hydrogen peroxide can decompose into oxygen and water to improve the oxygen content in the nutrient solution and provide essential oxygen for breathing of the plants; and the low-concentration plant hormone can promote the plant growth. The soilless culture nutrient solution has the effects of promoting quick growth of plants, effectively shortening the growth period of the plants and preventing the plants from being invaded by viruses and bacteria.

Description

technical field [0001] The invention belongs to the field of horticulture, and in particular relates to a nutrient solution for soilless cultivation. Background technique [0002] The composition of the nutrient solution in soilless culture is easy to control and can be adjusted at any time. It can be carried out in places with suitable light and temperature but no soil, such as deserts, beaches, and deserted islands, as long as there is a certain amount of fresh water supply. The suburbs and families of metropolises can also grow vegetables and flowers by soilless culture. The environment of soilless cultivation is artificially created crop growth environment, which can then replace the soil environment; soilless cultivation can be used to cultivate vegetables, and the vegetables grown without soil are pollution-free, and they are also green food; soilless cultivation can also be used To grow medicines, like many medicinal plants are root plants, they need a very good grow...

Problems solved by technology

[0003] In the prior art, there are also many deficiencies in the nutrient solution for soilless cultivation. The Chinese patent disclosed as CN103664310B discloses a nutrient solution for soilless culture of Asparagus asparagus. Substances, but the oxygen content in the nutrient solution is insufficient, because the roots also need to carry out aerobic respiration to help the material transport, the oxygen content in the nutrient solution is not enough to meet the needs of plant growth, so it is necessary to supply oxygen to the roots properly, the nutrient solution culture The plants grow slowly, are prone to diseases, and the plant survival rate is not high
