Efficient-use type culture medium for soilless culture and preparation method thereof

Abstract

The invention discloses an efficient-use type culture medium for soilless culture and a preparation method thereof. The culture medium is made of raw materials in the following parts by weight: an algae mixed solultion, potassium ferrate, diammonium phosphate, potassium sulfate, pyroligneous liquor, monopotassium phosphate, manganese sulfate, zinc sulfate, cobalt chloride, EDTA chelating sodium, nicotinic acid, glucose and appropriate water. The culture medium belongs to a colloidal property nutrient solution, viscosity coefficient of the nutrient solution is greatly improved, so that the liquid nutrient solution attaches on the surfaces of a root system when flowing through a crop root system, to form a membranoid substance, and absorb inorganic nutrients, greatly improving utilization rate of the inorganic nutrients and beneficial components. Contents of broken cells of algal cells contain growth activity assisting substances which are beneficial for crops, and contain an alkaloid component which has inset resistance effect, so as to reduce occurrence of pest and disease damages.

Description

technical field [0001] The invention belongs to the technical field of liquid culture substrates, and in particular relates to a high-efficiency cultivation substrate for soilless cultivation 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 ...
