How to topping management in loofah planting
Topping is an important task in the management of loofah and has a direct relationship with the yield of loofah. Usually when the main loofah vine has 13-15 leaves and the plant height is about 160 cm, the melon will be retained and topped, and then 1 melon will be topped for every 3 leaves. Under normal circumstances, this is feasible, but it is not suitable for loofah that grows weakly after planting.
The weakly growing loofah is topped according to the usual method, it is easy to appear "empty melon" phenomenon after harvesting 3-4 melons, and after the 3-4 melons are harvested, the stems become thin and weak, which is not conducive to the normal sitting of the loofah. melon. Therefore, for the loofah with weak growth, it is better to pick the core and raise the vines early in the empty seedling period to make the vines thicker, enhance the ability of the loofah to grow continuously, and prevent the "empty gourd" phenomenon. The author recommends topping when the main loofah vine has 11-12 leaves and the vegetative growth is vigorous, breaking the traditional practice of leaving the melon before topping, and consciously promoting the development of the vine. At this time, after topping, the side shoots germinate slowly, and the vines are thick due to sufficient nutrient accumulation. After the side shoots germinate, the melon can begin to retain. One melon is left for every 2 leaves, and the "empty melon" phenomenon will no longer appear.
Loofah topping technology
In the production of loofah, the traditional topping method is to leave the melon topping when the main vine has 13-15 leaves, and then leave the melon first and then topping. With this topping method, generally after 3-4 loofahs are harvested, the stalks are weak and the vegetative growth is poor. Some vegetable growers use the method of "raising vines with empty trees" to ensure the balance between vegetative growth and reproductive growth; some vegetable growers use the method of leaving a melon every 5 leaves to raise vines. But these two methods are not advisable, because neither can make the loofah gourd continuously fruiting during the fruiting period, resulting in a decrease in the yield of loofah gourd.
A vegetable farmer changed the topping method of loofah, topping in advance, topping first and then retaining the melon, and achieved high yield. He starts hanging the vine when the main vine has 7-8 leaves, and when the main vine has 11-12 leaves and the vegetative growth is relatively vigorous, he starts to topple the vine. At this time, the sprouting speed of the side branches slows down. The main vine is thick due to the sufficient nutrient accumulation. After the side branches germinate, the melon can be left. At this time, one melon can be left for every two leaves. With the phenomenon of empty trees and stubble, the yield of loofah is naturally high.
