Abstract

The invention discloses a nutrient medium for soilless culture, and belongs to the technical field of soilless culture. According to the technical field, the nutrient medium for soilless culture is prepared from, by weight, 5-10 parts of turfy soil, 0.5-1.5 parts of organic fertilizer, 0.5-2 parts of compound fertilizer, 3-5 parts of cow dung, 10-20 parts of bacterium stick waste residues, 10-20 parts of straw, 10-20 parts of wood bits, 3-5 parts of humic acid, 5-10 parts of coal ash, 5-10 parts of liquid microorganism bacterium liquid and 3-5 parts of amino acid. The nutrient medium for soilless culture has the advantages that nutrient elements are comprehensive, the production process is simple, the production period is short, the source of the preparation raw materials is wide, price is low, and the environment is not polluted; bacteria, saccharomycetes, actinomycetes and the like are compounded, the synergistic effect is achieved, multiple functions are achieved, and the effect is good; a large quantity of functional bacteria are bred, multiple special metabolites are generated, and therefore growth and development of plants are stimulated, and the disease resisting, drought resisting and cold resisting capacity of the plants is improved.

Description

technical field [0001] The invention relates to a soilless cultivation nutrient substrate, which belongs to the technical field of soilless cultivation. Background technique [0002] The research and application of soilless cultivation technology in my country started late, but compared with traditional soil cultivation, it has obvious advantages such as cleanliness, high yield, and strong adaptability. Therefore, soilless cultivation technology has also gained popularity in my country in recent years. Rapid development. Soilless cultivation can generally be divided into two types: substrate-free cultivation and substrate cultivation. The success of soilless culture production depends to a large extent on whether the formulation of the nutrient substrate is suitable and whether the nutrient management during the plant growth process can meet the requirements of different growth stages. [0003] At present, soilless culture substrates are mainly divided into two categories: ...
