Prevent tomato hollows from pouring “warm†water
In greenhouses, tomatoes are prone to external enlargement and hollow fruit with less meat, which not only directly affects yield, but also greatly reduces the quality and taste of tomatoes.
The direct cause of the hollow of the tomatoes is that the temperature of watering in the greenhouse is lower than 7°C. Under low temperature conditions, the roots of the tomatoes are cold-shrinked, the vitality of the roots is reduced, and the water absorption is poor. At this time, the tomatoes are in an expanding stage and the short-term lack of water cannot. Satisfying physiological needs leads to local meat loss. Although the ground temperature rose later, the roots recovered water, but the hollow part of the expanded fruit could no longer be enriched. Therefore, the temperature of the tomatoes in winter watered greenhouses must be raised to above 10°C in advance. Temporary storage of water can be used in the corner of the greenhouse to enhance temperature.
In addition, in order to prevent plants from being affected by freezing injury during the winter, water should be taken in a timely manner to prevent freezing and enhance the cold resistance of tomatoes. During the fruit development period, the appropriate quantity of Guozhuang Tiling capsule is added by spraying foliar fertilizer to regulate the vegetative growth of plants to reproductive growth, increase the amount of nutrient transport, increase the speed of fruit enlargement, preserve the fruits, and produce high-quality tomatoes. . When used, it is generally best to spray 1 time before flowering, young fruit, and fruit enlargement.
