Method for improving strawberry continuous cropping soil

Abstract

The invention discloses a method for improving strawberry continuous cropping soil. The method comprises the following steps of after the last crop is harvested, selecting continuous sunny weather, pulling out all plants with roots, performing pulverizing, turning into soil together with 25% pyraclostrobin emulsifiable concentrate, performing deep ploughing for 40-50 cm, covering with a plastic film for 2-3 days, and exposing in the sun for 2-3 days; 10-15 days before strawberry planting, applying 1-3kg of composite microbial inoculants per mu, performing deep ploughing for 40-50 cm, standingfor 5-6 days, properly applying organic fertilizer and Nashi 778 induction liquid per mu, and performing fine ploughing; and after beginning of spring, removing residual dead leaves and diseased or infected plants, applying glycan polypeptide biological potassium during intertillage, and after strawberries are harvested, applying green manure and a composite microbial agent between strawberry planting rows. According to the method, the granular structure of the strawberry continuous cropping soil can be effectively improved, pathogenic bacteria in the soil are removed, nutrient elements of thesoil are activated, the soil nutrient and fertilizer utilization rate is increased, and the yield and quality of the strawberries can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improvement method for strawberry continuous cropping. Background technique [0002] Due to the high moving cost of strawberry greenhouse facilities, the long annual production and use period (greenhouse strawberry is about 9 months from planting to the end of harvesting), coupled with limited cultivated land, it is difficult to rotate crops, and continuous cropping in facilities is very common, which causes soil pollution. The pathogenic bacteria and insect eggs in the shed have accumulated year after year, and some soil-borne diseases and insect pests such as Verticillium wilt and anthracnose have occurred year after year, and the disease has become more and more serious. Poor growth and development, mortality rate up to 30%, yield drop of 20%-50%, brought huge losses to strawberry production, seriously threatened the sustainable development of strawberry produc...

Poor growth and development, mortality rate up to 30%, yield drop of 20%-50%, brought huge losses to strawberry production, seriously threatened the sustainable development of strawberry production in facilities, and became a bottleneck problem restricting the development of strawberry production in some areas
