Abstract

The invention relates to the technical field of vegetable planting, in particular to a culture medium for soilless culture, which comprises the following components in parts by weight: 10-20 parts ofriver sand, 20-30 parts of plant ash, 1-5 parts of gabbro, 10-20 parts of Wali wormcast, 8-12 parts of mushroom residues, 1-2 parts of brewer's grain and 1-2 parts of bark powder. The pH value of theculture medium is 6.5-6.8, and the volume weight of the culture medium is less than 0.7g / cm<3>; According to the culture medium for soilless culture of vegetables, the Wali wormcast is added and has rich humic acid and a large number of beneficial microbial bacteria, 18 amino acids and various trace elements, and nutrients needed by plant growth can be provided. Beneficial active bacteria are contained, so that the fertilizer efficiency is slowly released and the fertilizer is continuously supplied. Wormcast is an organic matrix, the cation replacement capacity is high, and the buffering capacity, namely the acid-base property change alleviating capacity, of wormcast is high.

Description

technical field [0001] The invention relates to the technical field of vegetable planting, in particular to a culture substrate for soilless cultivation. Background technique [0002] Soilless cultivation refers to the fact that most of the root system grows in the nutrient solution layer, and only provides water, nutrients, and oxygen through the nutrient solution, which is different from the vegetables cultivated under the traditional soil cultivation form. Soilless cultivation has a short growth cycle and is rich in various vitamins and minerals necessary for the human body. [0003] Matrix cultivation is the main form of soilless cultivation, accounting for more than 90% of the total area of ​​soilless cultivation. There are many methods of matrix cultivation. At present in China, the trough and bag cultivation of composite substrates are the main forms. Rock wool cultivation is used in some agricultural industries. There are also applications in science and technology ...
