Talking about the four conditions for watering the crops in the greenhouse
The so-called modern greenhouses add some temperature, light, and humidity that can control plant growth parameters on the basis of traditional greenhouses to achieve a very good demand environment for plant growth, so that plants can reach very high yields. Growing water for crops is indispensable. Only reasonable watering can ensure the healthy growth of greenhouse crops and improve products. Next, the editor will share with you the four conditions for watering the crops in the greenhouse.
Watering of greenhouses needs to:
1. Watering flexibly according to the weather: we must grasp the principle of "appropriate watering on sunny days and avoid watering on windy and snowy days" according to the weather conditions. When the weather turns from sunny to cloudy, the water volume needs to be gradually reduced. The time can be lengthened appropriately. If it is from cloudy to sunny, the amount of water can be changed from small to large, and the interval time can be changed from long to short;
2. Watering should be focused: The temperature difference of various parts of the greenhouse is still relatively large, so the amount of watering is also to be used. The south of the greenhouse and near the heat source such as the stove and flue have a large amount of soil moisture evaporation. The amount of watering can also be appropriately increased. The temperature on the east and west sides of the greenhouse and the north is low, the sunshine time is short, and the amount of watering can be appropriately reduced;
3. Shallow water should not be too large: When the temperature is low, the crops in the shed will be slow and the water demand will be relatively reduced. Therefore, the watering volume should be small. Remember who to flood it. Watering or spraying should be appropriate. Roots of crops. In the first two days after watering, it is easier to cause humidity in the greenhouse. Therefore, reasonable ventilation and cooling are required to induce diseases. The ventilation is appropriate when the temperature is relatively high at noon;
4. Watering time should be appropriate: Watering of greenhouses should be arranged around noon. During this period, the temperature in the sheds is relatively high, and the side effects after watering are relatively small. Watering in the early morning and evening should be avoided to prevent the vegetables from freezing.
