Matters needing attention in summer high temperature shed

Growing vegetables in greenhouse for more than five years, there are many germs in the soil. With the continuous improvement of multiple cropping in greenhouse, soil-borne diseases are gradually raised, and the high temperature season is a good time to prevent and control the occurrence of diseases and insect pests. Growers can get twice the result with half the effort in the process of pest control as long as they master the method of stuffing the greenhouse. But the high temperature shed also needs to pay attention to some problems, let's take a look at it.

1. It is not suitable to apply biological fertilizer.

When ploughing and bottom fertilizer is applied in front of the stew shed, it must be noted that biological bacterial fertilizer should not be applied into the vegetable greenhouse together. If biological bacterial fertilizer is applied in front of the braising shed, then the biological bacteria in the biological bacterial fertilizer will be burned to death at high temperature in the process of the high temperature braising shed. Thus can not play the original role of biological bacterial fertilizer, resulting in waste and increased planting costs.

2. Film replacement

Under normal circumstances, the film in the greenhouse is changed once a year, and farmers can prepare the fields for ploughing and apply farm manure after the spring stubble vegetables are pulled out of the garden, making use of the old film at high temperature and stuffy, although the time of raising the temperature is slow, so it is necessary to appropriately prolong the time of the stew shed in the shed. However, it does not matter that the shed lasts a little longer, because the old film should be changed, and the new film should be replaced in time after the stew shed.

3. Remove the plant

For the greenhouse with serious root nematode in the greenhouse, the plant should be moved out of the greenhouse in time before the high temperature greenhouse, so as not to harm the plant in the greenhouse, which is harmful to the growth and development of the plant. In addition, many farmers put all the fertilizer in the base fertilizer into the greenhouse, covered with biological fertilizer, which is obviously wrong. Some vegetable farmers not only cooperate with methyl bromide fumigation at high temperature, but also cooperate with methyl bromide fumigation after applying enough base fertilizer containing biological bacterial fertilizer, which is even less worthy of promotion.

4. Shed time

In the shed, we should also pay attention to the time of the shed, using the new film is to raise the temperature quickly, but the film is seriously damaged, so it is necessary to properly control the time of the stew shed, generally after dry stew, and then wet stew for half a month. For some old sheds, the stew shed time can be slightly extended, but try not to exceed 20 days.
