The pre-growing period of sheds and capsicums is just in the rainy season. Rainwater entering the shed often leads to frequent occurrence of hot pepper diseases and severe dead trees. This year, the rainy weather lasted for a long time. Many vegetable farmers poured rain into the trees because they did not close the tuyers in time, causing them to die. Some vegetable farmers had been closed because of the greenhouses. The greenhouses had high temperatures, high humidity, and nutrient consumption. Poor sex, multiple pests and diseases, the weather turned cloudy, the long time is difficult to restore normal growth of vegetables.
When reporters interviewed Cai Xincun in Baocheng Sub-district, Changle County, the farmer Sien told reporters about a good way to prevent rain. That is to open a ditch under the outlet. When encountering continuous rainfall, as long as the rainfall is not large, you do not have to hurry to close the air outlet. In this way, not only can the continuous cloudy and rainy shelters not be ventilated, the temperature inside the greenhouse can be too high, and the nutrient consumption of the plants can be excessively large. It can also help to reduce the humidity in the greenhouse, improve the stress resistance of vegetables, and reduce the adverse effects of vegetables on the cloudy days. Influencing, killing more.
Master Tian's sheds used a total of four membranes. The two commonly used are mainly near the two air outlets on both sides. Therefore, two cisterns were installed in his shed, corresponding to the outlets. Both sides of the ditch are set to a width of about 50-60 cm, a depth of 20 cm, close to the shed to the height of the shed, to avoid flooding after the ditch full of water. The outermost pepper can be planted on the slope of a high ridge. Such a water storage ditch can store rain water that falls directly into the shed and flows down from the shed film. In addition, the chillies are far away from both sides, and there is no need to worry about the fact that the two films do not drop and affect the chillies during the rain.
At the same time, Master Tian reminded that such a storage ditch is mainly for rainfall with long rainfall and little rainfall. When the rainfall is large, the air outlet must be closed, and both sides of the shelter film should be put down. Do not allow rainwater to enter the shed.
