Balsam pear red handle

One is the high temperature. One of the important reasons for the red handle of young balsam pear is that the temperature in the greenhouse is too high in summer, and the high temperature can accelerate the ripening and aging of balsam pear, thus the red handle appears. If the temperature in the shed exceeds 35 ℃ for a long time, a large number of red handles will easily appear in the young balsam pear. Therefore, in summer, we must find ways to reduce the temperature in the greenhouse. Such as spraying mud on the greenhouse film, setting up a sunshade net, and so on.

Second, the strong light is direct. When the temperature is too high, excessive leaf thinning will aggravate the red handle of balsam pear. Therefore, in summer, in addition to shading measures in place, try not to remove branches and leaves, so as not to expose balsam pear to direct sunlight outside the branches and leaves.

The third is drought. Balsam pear likes to be moist, and if the shed is relatively dry, it will also promote the red handle of young balsam pear. Especially after summer, some vegetable farmers still do not remove the plastic film, and the air in the shed is dry, which aggravates the occurrence of balsam pear red handle. Therefore, in addition to watering the summer shed to prevent drought, it is also necessary to remove the plastic film in time and increase the air humidity in the shed.
