How to disinfect the strawberry field?

How to disinfect the land where strawberries are grown? Please guide the soil disinfection treatment of strawberry orchard is an important technical measure to ensure the increase of strawberry production and income. The sunny, hot and hot weather in July and August is a favorable time for soil disinfection in strawberry growing areas (especially in continuous cropping areas). According to the actual situation of our city, several methods of soil disinfection are introduced for strawberry growers' reference. First, the use of solar energy high temperature soil disinfection operation technology: before disinfection, first clean up the field, the previous crop is the rice field, after the rice harvest, the rice stalk chopped back to the field. Then 2000 kg of rotten manure or 500kg of chicken manure was applied per mu, plus 100kg of cake fertilizer and 50kg of cooked lime. After ploughing, the field was irrigated with a certain water layer (half of the soil). Then the soil was closed covered with agricultural film, and the soil was disinfected using the energy produced by high temperature in summer and decomposition of organic fertilizer. The mulching time of agricultural film should be more than 20 days, and the longer the mulching time is, the better the effect is. After the film was removed, the field water was naturally absorbed by the soil, and then 50 kg of compound fertilizer and 50 kg of phosphate fertilizer were sprinkled to make a bed. Second, the soil disinfection dosage of Mianlong or Rongbao (lime nitrogen) soil disinfection is 20 kg per mu, and the soil disinfection dosage of Rongbao (lime nitrogen) is 40 kg per mu. Operation techniques: clean up the field, apply sufficient rotten base fertilizer and base fertilizer, evenly apply Mianlong or Rongbao (lime nitrogen) to plough the soil; or use board sowing machinery to open ditches, use Mianlong or Rongbao (lime nitrogen) as ditching lines, and the excess chemicals can be evenly spread over the fields to ensure that the chemicals are evenly distributed in 15-20 centimeters of the soil during mechanical ditching. If the soil is too dry, you can properly sprinkle and water the ground to maintain a certain soil moisture; that is, cover the closed garden with agricultural film for about 10 days, prepare the bed or loosen the border surface after opening the film, and at the same time, carry out a comprehensive irrigation to the garden to speed up the chemical volatilization, and wait 5 days before planting strawberries to avoid injury to the seedlings.
