Water Management measures of Tomato in greenhouse

The first inflorescence blossoms, on the basis of watering enough planting water after planting, control watering at slow seedling stage and after slow seedling, and do not water easily until the first ear flower blossoms, so as to prevent flourishing and falling flowers, and less watering in case of drought, so as to promote flowering, fruit setting and prevent falling flowers.

From the first inflorescence to the third inflorescence, watering should be strictly controlled to promote the root system to develop into the deep soil. Unless the growing point wilts at noon, small water can be irrigated along the trench. If there is too much water during this period, the plant is easy to grow and flourish, resulting in falling flowers and not easy to set fruit.

When the third inflorescence blossoms, the first ear fruit enters the expansion period, at this time begins to water, the amount of water should be sufficient, but also do not flood irrigation, to water under the film. Sufficient water can not only ensure the normal growth of stems and leaves, but also promote the development of fruit and promote the expansion of fruit.

Severe cold season (mid-late December to early February): in this stage, the temperature is low, the light is weak, plant growth and fruit growth are slow, so watering must be properly controlled.

The warming stage after the middle of February: the temperature gradually increased, the growth of plants and fruits accelerated, and the water demand also increased gradually. it is necessary to choose sunny morning watering, gradually increase the watering times, and water once about 15-20 days in spring. however, it is necessary to grasp the principle of "watering the fruit without watering the flowers" so as not to reduce the fruit-setting rate.
