Momordica charantia is a stalk vine. It has a strong ability to sprout branches and vines. It needs to be rearranged during the growth process to improve yield and quality. In general, it can be summarized as pruning and branching, which can ensure good ventilation and light transmission between plants and reduce unnecessary nutrient consumption. So how should bitter gourd be pruned?
1. Introducing vines When the bitter melon vine grows to about 40-50 cm, you need to set up or tie the rope to hang the vine, so as to draw the vine on the shelf to form the melon. You can use nylon ropes to tie the middle and lower parts of the vine. The sling is tied to a wire or scaffold about 2 meters high above the planting border. It should be noted here that when hanging the vines on the shelf, pay attention to the direction of the main vines in each row, so that the leaves are evenly distributed, can use the space to obtain more light, and at the same time properly remove less than 30 cm Part of the side vines to reduce nutrient loss.
2. Topping and topping After the main vine of bitter gourd is put on the shelf, topping and topping are needed. Choose 2~3 strong and strong side vines as the fruiting vines. The side vines should retain the first 2 leaves of the fruit after the fruiting. After discounting, the melons on the side vines should be cut off in time after harvest to promote the germination of new vines. In addition, the raw vines, disease worms, weak vines, melon vines and rainy tendrils on the stem vines should be removed in time, which can reduce the unnecessary nutrient consumption of the plants and increase the permeability to synthesize more Nutrients promote plant growth. It should also be noted that whenever two female flowers grow on the side of the vine, one should be kept full and vigorous, and the other with poor development should be removed in time.
3. Picking leaves When the bitter gourd enters a large amount of fruiting period, in order to avoid the overgrowth of the invalid stem vine leaves and affect the sitting melon and the swelling melon, the old yellow diseased leaves in the middle and lower parts of the plant, the branch of the non-melon branch, the top of the flowerless The branches of melons, as well as the fruits of diseases and insect pests and deformed fruits are all cut off. This can save nutrients and promote sitting melon and swelled melon.
