Soilless culture method for vegetables

Abstract

The invention provides a soilless culture method for vegetables. According to the soilless culture method, (1) a seedling culture medium comprises 10-20 parts of bagasse, 15-30 parts of tea leaf residues and 3-4 parts of a composite fermentation material, wherein the composite fermentation material is obtained from pine nut shells, chestnut shells, chaff and cottonseed hulls in a mixed, decomposedand fermented mode; (2) the thickness of the seedling culture medium is 15-20cm; steps of sowing vegetable seeds, covering a mixture of the seedling culture medium and bran ash, and spraying wet arecarried out; (3) a seedling culture medium comprises 5-15 parts of bagasse, 5-10 parts of tea leaf residues, 10-20 parts of beet pulp, 5-8 parts of a composite fermentation material and 10-20 parts ofexpanded perlite; and (4) vegetable seedling field planting is carried out, and thickness of the seedling culture medium is 20-30 cm. By means of the cultivation method, the physicochemical propertyof the medium can be effectively kept, accumulation of germs and eggs in the medium is restrained, the stable high seedling rate of vegetable seedlings and the high survival rate of vegetable transplanting are guaranteed, the germ infection rate is reduced, and continuous, stable and high-quality production of soilless cultivation of vegetables is achieved.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a method for soilless cultivation of vegetables. Background technique [0002] With the advancement of science and technology, soilless cultivation technology is widely used in the development of facility agriculture and modern agriculture. Vegetable soilless cultivation technology is also gradually developing in the direction of large-scale production, intelligent management and high economic benefits. [0003] However, in the existing soilless cultivation process of vegetables, with the use of the cultivation substrate, especially in the case of continuous cropping, due to the influence of the external environment, irrigation and fertilization management, it is easy to reduce the quality of the substrate and cause the accumulation of germs and bacteria. Insect eggs, which lead to large-scale infection of vegetable roots, especially in the process of seedling culti...

Problems solved by technology

[0003] However, in the existing soilless cultivation process of vegetables, with the use of the cultivation substrate, especially in the case of continuous cropping, due to the influence of the external environment, irrigation and fertilization management, etc., it is easy to reduce the quality of the substrate and cause the accumulation of germs and bacteria. Insect eggs, which lead to large-scale infection of vegetable roots, especially in the process of seedling cultivation, the disease resistance of vegetable seedlings is prone to decrease, the germination rate and seedling rate are low, the slow seedling time after planting is prolonged, and the transplanted seedlings grow Therefore, it is necessary to find a soilless vegetable cultivation method that is scientific and reasonable, has a high survival rate and stable growth, so as to achieve a stable high seedling rate and a stable growth rate of vegetable seedlings. High survival rate of vegetable transplanting, reduce the infection rate of pathogens, and promote the sustainable and stable high-quality production of vegetable soilless cultivation
