Problems solved by technology

CN 101544512A discloses a method for preparing flower soil with edible fungus chaff. In the method, the dried and pulverized edible fungus chaff is mixed with garden soil, river sand and mountain mud, and fermented at 25-35°C for 20-40 days. Flower soil is prepared, but the disclosed fermentation temperature is 25-35°C, which cannot kill pathogenic bacteria, insect eggs and grass seeds in the garden soil. Therefore, this method cannot obtain seedling soil without soil-borne diseases

Abstract

The invention relates to a manufacturing method for seedling culture soil free of soil-borne diseases. The manufacturing method includes the steps of preparing, water content adjusting, fermenting and the like. According to the manufacturing method, raw materials are easy to obtain, the processing technology is simple, conditions are moderate, harmful pathogenic microorganisms can be killed fully to obtain the seedling culture soil free of the soil-borne diseases, and influence of plant diseases and insect pests is greatly relieved, so that the growing environment of crops is improved remarkably, and the morbidity of the crops is reduced remarkably.

Description

【Technical field】 [0001] The invention belongs to the technical field of nursery stock cultivation. More specifically, the present invention relates to a method for preparing seedling soil for soilless diseases. 【Background technique】 [0002] Soil-borne diseases refer to diseases caused by pathogens surviving in the soil that attack crops from the roots or stems of crops under suitable conditions. Common soil-borne diseases include capsicum, eggplant, cucumber damping-off, blight, blight, root rot, blight (yellow) wilt; bacterial wilt of tomato and pepper; soft rot of Chinese cabbage; rape, lettuce Sclerotinia; wheat take-all; cotton blight, red rot, verticillium wilt and nematodes, etc. Once soil-borne diseases occur in the early stage of crop growth, the seedlings will die soon due to root rot or stem rot and damping, which will seriously affect crop production. When diseases occur in the late growth period of crops, the yield will be reduced by 20-30% in general years...
