In the winter greenhouse, the zucchini should be properly picked during the melon period, and the measures should be taken to ensure the growth and high yield.
As the plants continue to grow, the leaves gradually increase, which tends to cause depression in the field, poor ventilation and light transmission, and the lower leaves are difficult to see light for photosynthesis. Especially in the deep winter season, the temperature in the shed is low, the humidity is high, and there are many pathogens. In addition, the lower leaves are easily broken and broken after spraying, picking melons, etc., which easily lead to disease. Therefore, it is necessary to improve the ventilation and light transmission of the zucchini.
The leaf picking should be based on the growth of the plant. If the growth is strong, the leaves should be picked more, and the weak ones should be picked less to ensure that the ventilation and light transmission in the field is good. In order to avoid the stalks are difficult to heal after injury, it is recommended that the vegetable farmers only go to the leaves without going to the handle. Because the petiole is thick and brittle, the leaves are removed from the base, and the stem is prone to large wounds, which are not easy to heal, and the leaves can be removed all or most, which can cause the petiole to dry out more quickly. In addition, it should be noted that it is best to have several consecutive sunny days when removing the leaves, so that the environment inside the shed is relatively dry and not susceptible to disease. After picking the leaves, the vegetable farmers can spray streptomycin 4000 times solution or Garonong 600 times solution to prevent disease infection in advance.
Excessive female flowers must be removed early to reduce nutritional competition and promote sitting. The amount of female flowers to be removed should be determined according to the growth of the melons. The weaker should first remove the root melon, and then leave a female flower every three quarters; the melon can grow strong and leave the root melon, but it should be harvested early, and then leave a female flower every two or so.
