Problems solved by technology

The method of cultivating seedlings using soil is a traditional method of raising seedlings, which brings insect sources and disease sources to greenhouse vegetable production, and also brings continuous cropping obstacles to soil cultivation and seedling cultivation. If the method of soil cultivation and seedling cultivation is continued, soil disinfection must be carried out. Disinfection will inevitably increase the cost of seedling cultivation, and it will easily cause environmental pollution, which is not conducive to the industrialization of seedling cultivation, and soilless cultivation technology has become an inevitable choice

Description

technical field [0001] The invention relates to the technical field of nutrient soil, in particular to a special nutrient soil for vegetable greenhouses and a preparation method thereof. Background technique [0002] Nutrient soil for seedling cultivation is a high-quality soil or soilless cultivation nutrient soil prepared by using organic and inorganic materials and microbial preparations according to the needs of seedling growth. The method of cultivating seedlings using soil is a traditional method of raising seedlings, which brings insect sources and disease sources to greenhouse vegetable production, and also brings continuous cropping obstacles to soil cultivation and seedling cultivation. If the method of soil cultivation and seedling cultivation is continued, soil disinfection must be carried out. Disinfection will inevitably increase the cost of seedling cultivation, and it will easily cause environmental pollution, and it is not conducive to the industrialization ...
