Pruning technology of bitter gourd
When the bitter gourd is 40 cm high, the nylon rope is used for traction, and the vine is tied to the 2 m high wire above the middle of the planting hoe, so that the bitter gourd relies on the above result. A few days later, the vines were crawled onto the shelves, and each row of main vines was pulled in one direction. When the vine is put on the shelf, let the main vine straight up, and at the same time pay attention to let the leaves evenly distribute and make full use of the growth space.
After pruning, when the main vine climbs onto the shelf, keep 2-3 strong side vines and the main vines laterally wound onto the shelf. To ensure good ventilation and light transmission conditions and reduce nutrient consumption, the other side vines and tendrils below the shelf Can be removed all. The newly grown side vines on the shelf are preserved by the melons, and the melons, weak vines, and pests are removed in time. When two female flowers appear on one side of the vine, one of the female flowers can be removed, and the female flower with good quality of the melon can be preserved. After the first melon is finished, it can be removed properly. Each plant retains 5-6 side vines, and the main and side vines can be allowed to grow. It is not necessary to pick the heart. If the growth space is narrow, the topping can be performed after each vine is stabilized. With the extension of time, the amount of melon is getting bigger and bigger, the vegetative growth is weakened, the reproductive growth is strengthened, and the middle and late stages can no longer be pruned, but the old leaves, yellow leaves, diseased leaves and the lower part of the wire must be removed in time. No melons and vines to prevent consumption of nutrients. Of course, the top without melons, no female flowers, and sick vines should be removed in time, and the pests and diseases should be removed in time.
