After the end of the shack, the following three points should be grasped.

Replenishing biological bacteria in time after high temperature suffocation

After high temperature, no matter whether it is harmful bacteria or beneficial bacteria, it is killed a lot, and the soil is in the “blank” stage. Many vegetable farmers feel that the effect of high temperature suffocation is not good, and the disease is even worse than that before the shack. The reason is that the beneficial bacteria are not replenished in time. Once the pathogens are introduced first, the inhibitory effect of the beneficial bacteria is lacking, and the pathogens will be faster and more violent. Breeding, causing the disease to become heavier after the shed. The biological bacterial fertilizer is evenly applied to the colonization hole at a dosage of 80-120 kg per mu before planting the plant to protect the rhizosphere environment and enhance the disease resistance of the plant.

Do not plant vegetables immediately after peeling off the film

Because the soil is accompanied by organic fertilizers such as farmyard manure, a large amount of ammonia gas is produced in the process of high-temperature fermentation. Therefore, vegetables should be planted 5 to 7 days after the film is ventilated to prevent gas damage.

Be careful of re-introduction of pests and diseases after shacking

After a period of high temperature suffocation, the pathogens in the shed have been basically killed. There are fewer pathogens in the shed, and it does not mean that vegetables will not get sick. Seedlings, farm tools, shoes, etc. may bring the pathogens back into the shed.

When the high temperature is shackled, it is necessary to put the commonly used tools such as vegetable baskets, hoses, shovel, shovel, rotary tiller, and work clothes and work shoes into and out of the shed into a shed and boring; work in the shed The clothes and shoes are preferably used exclusively, and the sheds should be replaced; the seedlings should be soil-free, and the nursery soil must be disinfected to prevent or reduce the re-invasion of foreign germs and nematodes.
