How to water the vegetable greenhouse in winter to produce a bumper harvest?

In a greenhouse with a closed environment, when the humidity of the air increases, the disease is very likely to occur and spread. In addition to the autumn and winter seasons, the temperature is low, and low temperature freezing may occur. Therefore, today's Xiaobian will be in the watering technology, what time do you want!

 

　　 1. How to water?

 

Under the membrane, under the membrane, if there are conditions, under-film percolation can be carried out. This can effectively prevent the evaporation of moisture on the ground, reduce the humidity of the air in the greenhouse, and prevent the occurrence of diseases.

 

　　 2. When is watering?

 

The watering is best chosen in the morning on a sunny day; at this time, the water temperature is close to the ground temperature, and the root system is less stimulated and easy to adapt after watering. At the same time, the ground temperature recovers quickly so that there is enough time to remove moisture from the greenhouse. Watering in the afternoon will suddenly change the ground temperature, thus affecting the physiological functions of the root system. It is not advisable to water in the afternoon, evening or rain or snow.

 

　　 3. How much water is poured?

 

In winter, the amount of water in the greenhouse should be determined according to the weather and the growth of the plants. It is not suitable for flooding.

 

Because this will significantly reduce the ground temperature, hinder the absorption of nutrients by the roots, and affect the normal growth; the second is that it is easy to increase the humidity of the air in the greenhouse, causing disease.

 

　　 4. What should I pay attention to after watering?

 

On the day of watering, if you want to restore the ground temperature as soon as possible, you should close the greenhouse and increase the temperature inside the shed to promote the temperature. After the temperature rises, it is necessary to timely ventilate and dehumidify, so that the indoor air temperature is kept within a suitable range to facilitate the robust growth of the plants.

 

Watering vegetables in greenhouses should pay attention to large, medium and small, and greenhouse watering is more stressful: it depends on the sky, but also on the ground, but also on the situation. Only in this way can we guarantee a bumper harvest.
