A method for repairing and utilizing vegetable soilless culture substrate

Abstract

The invention discloses a method for repairing and utilizing soilless cultivation substrates of vegetables, which comprises the following steps: 1) preparing raw materials such as corn stalks, cow dung, organic fertilizers, and biological bacterial fertilizers; In the process, open a "V"-shaped ditch with a length of 9m, a depth of 20cm, and a width of 20cm on the surface of the old substrate; 3) Fill the bagged corn stalks into the opened ditch; 4) Cover the fermented cow dung on the corn stalks; 5) Mix organic fertilizer and biological bacterial fertilizer, and sprinkle it on the cow dung; 6) Backfill the old substrate in the substrate tank, level the surface of the substrate, with a thickness of 12-18cm; 7) Lay drip irrigation, and wet the substrate with clean water After planting vegetables, enter normal production management. In the process of vegetable growth, biological bacterial fertilizer can produce microorganisms, decompose cow dung, and the straw at the bottom can produce carbon dioxide, which is gradually fermented and matured, increasing organic matter, improving the rigidity of the substrate, beneficially improving the vegetable rhizosphere environment, and promoting vegetable crops. grow.

Description

technical field [0001] The invention relates to the field of soilless cultivation of vegetables, in particular to a method for repairing and utilizing a substrate for soilless cultivation of vegetables. Background technique [0002] Since 2001, Suzhou District has introduced organic ecological soilless cultivation technology from the Chinese Academy of Agricultural Sciences in the production of solar greenhouses. At present, it has built the largest soilless cultivation production base in the country, with a promotion area of ​​15,000 mu. Vegetable production in the Gobi solar greenhouse has developed rapidly and has become one of the advantageous industries for increasing agricultural efficiency and increasing farmers' income. However, due to the high one-time input cost of the substrate, the organic content of the substrate will decrease after many years of planting, which is not conducive to the normal growth of vegetables. It is necessary to supplement a part of organic ...
