Nutrient solution for liquid culture of strawberries and preparation method of nutrient solution

Abstract

The invention discloses a nutrient solution for liquid culture of strawberries and a preparation method of the nutrient solution. The nutrient solution is prepared from the following raw materials in parts by weight: an alga mixed solution, potassium ferrate, aluminum sulfate, ammonium sulfate, magnesium sulfate, sodium selenite, vermiculite powder, corn bran, garlic straw, lightyellow sophora roots, biogas residues, boric acid, potassium humate, potassium polyphosphate, calcium nitrate and a proper amount of water. Combined with inorganic elements in a proper proportion according to growth requirements of the strawberries, a broken alga cell solution is adopted as a basic chelating solution and becomes an intermediate for establishing relation between roots and nutrients, the role of nutrients is fully played, the vermiculite powder and some organic materials are ground into fine powder and mixed with a culture solution, the fine powder is fully mixed with the culture solution under the action of high-speed shearing, the density of the nutrient solution is increased, the flow rate of the nutrient solution is reduced, the oxygen content of the liquid culture solution is increased, threat of pests is avoided, and resources in all aspects are saved.

Description

technical field [0001] The invention belongs to the technical field of liquid culture solution, and in particular relates to a nutrient solution used for liquid cultivation of strawberries and a preparation method thereof. Background technique [0002] The advantage of soilless cultivation is that: using a liquid nutrient matrix, you can directly dissolve mineral salts in liquid water, and then provide nutrients in a flowing manner. Without the support of soil, the crops can directly absorb nutrients from the root system, which greatly saves Manpower and land resources, while also saving fertilizer and avoiding environmental problems caused by fertilizer loss; however, several problems of the liquid culture mechanism need to be improved, and greater benefits will be obtained. [0003] The form of nutrient absorption by the root system of crops is mainly from the root hair area of ​​the root tip of the fibrous root system in the root system, from the meristematic area and elo...

Problems solved by technology

[0005] The purpose of the present invention is to study a liquid soilless planting substrate, provide all the nutrient elements and growth active substances for crop growth, improve the utilization rate, and solve the rot caused by the good fluidity of the substrate but the poor element adhesion and low air permeability in the past. and pest problems, specifically through the following methods:
