Method for repairing soil for strawberry cultivation

Abstract

The invention discloses a method for repairing soil for strawberry cultivation. The method comprises following steps: 1. after the current crop is harvested, 700-800 kg per mu of organic compost, straw and wheat straw are evenly laid on the soil surface of the greenhouse; at the same time, the cyanamide calcium is uniformly applied on the surface of the greenhouse soil in an amount of 30-40 kg permu; rotary tillage by a rotary tiller is performed to uniformly mix the above materials with the soil; 2. covering the surface of the furrow with a transparent old plastic film to seal the soil; 3. closing the greenhouse and filling the furrow with water to make water penetrates the whole surface and make the soil wet for a week; 4. continuing to close the greenhouse for 20 to 25 days; 5. after the greenhouse is closed, the old film covering the surface layer of the soil is removed, and the microbial agent is added. The invention kills the pathogens in the soil by calcium cyanamide, and thensupplements certain organic fertilizers to make the soil suitable for strawberry growth, thereby ensuring sustainable cultivation of strawberries and ensuring strawberry yield.

Description

technical field [0001] The invention relates to a soil restoration method for strawberry cultivation, which is applied in the technical field of strawberry cultivation. Background technique [0002] Strawberry is a perennial herb.

Problems solved by technology

There are many growers who cultivate strawberries in the market. As strawberries are perennial plants, the annual production and use period is long, causing long-term accumulation of pathogenic bacteria and insect eggs in the soil in strawberry greenhouses, and soil acidification and nutrient imbalance appear one after another. Therefore, if you want to grow strawberries Continuous cultivation of strawberries in greenhouses requires restoration of the cultivation soil to ensure the yield of strawberries, but there is no good restoration method on the market at present
