How to properly water greenhouse vegetables? Planting vegetables in the greenhouse, watering can be said to be one of the most important links, especially in the winter, more watering, prone to rotten roots or frost damage, less watering, and can not meet the demand for water for vegetable growth. Therefore, it is very necessary to master the correct watering method. Next, the method of correct watering of greenhouse vegetables brought by Xiaobian.
Watering the greenhouse should take the following four countermeasures:
First, low temperature shallow water
Especially in the winter with low temperature, because the vegetables in the greenhouse are evaporated slowly, the water demand is not large. Therefore, watering in a small amount is not required to be watered every day, and the watering time is longer. When watering, do not flood the water, and choose the watering method of watering or spraying, so as to avoid the roots of vegetables because of the low temperature. Hui Nong Network Xiaobian reminds here that since water is added during the watering, it will cause the humidity in the shed to increase. Therefore, proper ventilation and cooling should be carried out to prevent the occurrence of diseases. The ventilation time should be selected in the temperature comparison. High noon is most suitable.
Second, the watering time is appropriate
The temperature in winter is low, so when watering, it is best to choose watering around noon, preferably after 10 am and before 3 pm, because the temperature in the greenhouse is relatively high, after watering The side effects are relatively small. Never water in the morning or in the evening, because the temperature in the greenhouse is relatively low at this time, which is caused by watering the vegetables. It is best to use well water for watering, because the temperature of the well water in winter is relatively high, which can effectively reduce the physiological stimulation of watering on vegetables.
The third is to see the days of flexible watering
When watering, watering according to the weather conditions, if it is sunny, the water evaporates quickly, so it can be watered more; the water evaporation in the cloudy day is not big, so it can be watered or not watered; Prevent the freezing of vegetables; if the weather is sunny and sunny, reduce the amount of watering, and the interval of watering can be lengthened appropriately; if the weather turns from cloudy to sunny, increase the amount of watering slowly, and the interval between waterings should be Shortened.
Fourth, watering should be focused
Since the temperature in various places inside the greenhouse is different, there are all differences when watering. For places close to the south and near heat sources such as stoves and flue, due to the large amount of soil moisture evaporation, the amount of water can be increased, while the temperature on both sides of the greenhouse is lower on the east and west, and the sunshine time is shorter, so the amount of water is watered. Can be less.
