Covered post management

With the advent of cold air, the sheds and greenhouses have been covered with films. After the film is covered with vegetables, it enters a critical period of growth. The management of this period is particularly important.

Coating time

Cover film should be selected in the morning on a sunny day to avoid the rainy weather, especially the windy weather. If there is a strong wind above Class 3, the laminating work must be postponed. When the film is to be covered, it is necessary to leave enough space for the additional insulation device according to the situation.

Film selection

After the newly purchased greenhouse membrane is covered, it is necessary to intensify the ventilation so as not to harm the crops with harmful gases that are volatilized from the plastic membrane. If the temperature is not very low at night, consider day and night ventilation. For sheds with odor after coating and abnormal crop leaves, look for the cause in time. If it is caused by the quality of the shed film, remove the shed film as soon as possible. The old film must be thoroughly cleaned before use. Otherwise, the dust on the film will affect its light transmission and thus affect the photosynthesis of the crop. Prolonged lack of light or a sudden drop in light intensity can cause plant leaves to yellow, fall, and drop.

Strengthen management

The mulching of greenhouses has changed the microclimate of crop growth in a short period of time. Therefore, appropriate measures should be taken during this period to slow down the changes in light, temperature, and humidity and make the crops have a new environment. Gradually adapt to the process and then enter the day-to-day management of a solar greenhouse or plastic greenhouse.

To reduce the number of irrigation water in places where conditions permit, change irrigation methods and avoid flooding. After the watering, it is necessary to strengthen the ventilation and light transmission to avoid the diseases caused by excessive humidity.

After the prevention and treatment of the diseased worms, the temperature and humidity in the sheds will suddenly increase, and the latent pathogens or eggs may cause harm, so it is necessary to prevent and control them as soon as possible. Even minor diseases or insect pests must be taken seriously because high-temperature, high-humidity environments can spread rapidly, and pests and diseases must be controlled early in the disease. The diseased plants should be brought out of the shed to be destroyed or buried in order to cut off the source of infection and lay a good foundation for the post-management of the shed.

To prevent the occurrence of gas damage, it is necessary to select a sufficiently mature organic fertilizer. Fertilizers should not use fertilizers with high volatility and must be buried deeply. Because in the environment of the greenhouse, any unfavorable gas will cause harm to the growth of the crop.
