Humidity in winter sheds is high, especially when it comes to continuous yin weather, which can easily cause the infection and outbreak of vegetable diseases. Recently, the reporter saw Wang Zaiming in the shed of Sunji Street in Shouguang City. He noticed that there were few condensations in his cucumber shed, few diseases in the plants, and almost no spots on the leaves.

When a reporter asked how to control the humidity in the shed, Master Wang said that “increasing or reducing the combination†was a measure he had taken in recent years to reduce the humidity in the shed.
Master Wang said: "The reduction is to reduce the amount of evaporation on the ground. This includes sampans and sheds. He puts sawdust, wheat straw, etc. to absorb moisture on the mulch, and these sawdust and straw can be In the following year, it will be turned into soil for organic fertilizer, and wet soil can be used to reduce the evaporation of water by means of a cover film or film, or a film can be hung on the front wire, and a flow tank can be placed under it to make the water left on the film flow out. Outside the shed, increase the temperature and reduce humidity, cucumber can still grow normally at a high temperature of 35°C, so under the premise of not affecting the normal growth of crops, the temperature in the shed can be appropriately increased to 35°C during the day and can be put in the shed. The water vapor evaporates into the air as quickly as possible, after which ventilation can reduce the humidity in the shelter more effectively."
Reporter: "You say 'increasing or reducing the combination' is indeed an effective measure to reduce the humidity in the greenhouse. If you can change 'one increase and one decrease' to 'two increase and two decrease', the effect will be better."
Master Wang suddenly came to an interest and quickly said, “You listened.†“Reduce†also reduces film condensation. This requires the selection of a high-quality non-drip film, including a film after the vent. Discovered through the operation, The pesticide synergist 'Jiexiaoli' or bean flour evenly sprayed on the film can effectively reduce the amount of film condensation on the film.'Increase' should be divided into times of ventilation, increase ventilation time and reduce humidity. Next, early opening and late closing, sub-ventilation, extended ventilation time. Not only can discharge moisture inside the shed, but also allow carbon dioxide to enter the shed early to facilitate photosynthesis."
Master Wang said with great pleasure after hearing: "After changing 'one increase and one decrease' to 'Two increase and two decrease,' the humidity in the greenhouse can be reduced more effectively and the incidence of diseases can be reduced."
The temperature-controlled pumpkin gourd has a long way to go. The Qingzhou Dengong Supermarket is in Chungchun. Qingliu City, Gaoliu Town, has more vegetable growers. Because the greenhouses are new greenhouses, the vegetable growers have already installed straw curtains. The temperature will be maintained at about 18°C, while the zucchini is cool and the high temperatures will cause the zucchini to prosper. However, many vegetable farmers now think that the zucchini has not only grown up but has grown slowly. What causes the poor growth of the zucchini?
For this reason, the author went to the vegetable shed to investigate. The original vegetable grower controlled the length of the zucchini, but in the evening, he did not put the straw curtain. Since there are more cloudy days, the temperature of the outside night falls below zero, and the vegetable farmers do not put grass in the evening. In the case of curtains, the temperature in the shed will be lower than 10°C, which will cause a significant decrease in the temperature of the ground and inhibit the growth of the root system of the zucchini, so that the root system of the zucchini can not absorb enough nutrients and cause the growth of the squash to become weaker and weaker. In order to control the growth of the squash, the vegetable farmers achieved the goal by lowering the temperature inside the shed. However, there is a certain degree of cooling. For the squash, neither the prosperous growth nor the flowering fruit setting is maintained at 20-25. °C, the most appropriate temperature at night is 12-15 °C.
Therefore, the control of the length of the squash by reducing the temperature of the shed should be well controlled. If the temperature in the shed is too low, it can lead to poor growth of the squash, and the vegetable grower can adopt the method of placing grass curtains at night or putting the woven straws only two-thirds. Reduce the temperature of the greenhouse and create a suitable temperature environment for the growth of zucchini.
