How to disinfect strawberry?

Strawberry soil disinfection is an important technical measure to ensure that strawberries increase production and income. In July and August, the hot and sunny weather is an opportunity for soil disinfection of strawberry plantations (especially continuous cropping areas). According to the actual situation of the city, several soil disinfection methods are introduced for reference by strawberry growers.

First, the use of solar thermal soil disinfection method

Operation technology:

Before the disinfection, the plots were cleared and the former was a rice field. After the rice was harvested, the rice straw was chopped and returned to the field. Then the mu is applied to 2,000 tons of decomposed bar fertilizer or 500 kilograms of chicken manure plus 100 kg of cake fertilizer and 50 kg of slaked lime. After spreading, the field is filled with a certain water layer (half of the clod).

Then cover it with agricultural film and use the energy generated from the decomposition of high temperature and organic fertilizer to disinfect the soil. Coverage time for agricultural film is more than 20 days. The longer the coverage, the better the effect. After removing the film, the water in the field was allowed to dry naturally, and then 50 kg of compound fertilizer and 50 kg of phosphate fertilizer were applied to the acre to make it dry.

Second, cotton or lime nitrogen soil disinfection method

The dosage of 20 mu for each mu used for the disinfection of soils with cotton bactericides and 40 kg per mu for soil disinfection with Rongbao (lime nitrogen) chemicals.

Operation technology:

Clean up the plots, apply enough base fertilizer and base fertilizer, evenly apply the cotton or Rongbao (lime nitrogen) agent to plow the soil, or use the sowing machine to open the ditch, and use the cotton or Rongbao (lime nitrogen) agent Ditch the line, the excess agent evenly spread in the field, in order to ensure that the pesticide is evenly distributed in the soil 15-20 cm when the machine is open; if the soil is too dry, the ground can be sprinkled with water to maintain a certain degree of soil moisture. And cover the agricultural film with closed field for about 10 days. After uncovering the film, we will make soil or vent loose soil. At the same time, we must carry out a full irrigation of the garden to accelerate the volatilization of the medicine. After 5 days, we can plant strawberries, so as to avoid Injured seedlings.
