If necessary, pour small water under the membrane to avoid lowering the temperature.
Increase the amount of water after the weather warms to meet the fruit growth and development. Tomatoes grown in greenhouses in early spring should be watered in time to meet their water requirements.
Third, according to growing water. The plant is dark green, with shiny, green and flat leaves and stretched heart and leaves. It is a uniform and appropriate expression of water. Such as the heart leaves are not shrinking, dark green leaves, sunny days with mild leaf sagging for the lack of water performance, to timely supply of water.

The results of early colonization is smaller, the amount of leaf evapotranspiration is small, the number of fruit is also small, ventilation is also small, usually 7 to 10 days pouring a water, (the amount of water should be small). Later, with the growth and development of the plants, the number of fruits increases, the ventilation volume increases, and the amount of transpiration increases. The number of watering intervals and the amount of watering should be shortened to keep the soil dry and wet (mainly wet). The water can be poured for 5 to 7 days. The soil should be kept moist during the harvest period to increase the fruit weight.
