1. After removing the male and female melon vines, the buds should be continuously plucked and the appropriate number of male flowers should be removed. The loofah usually only has one main vine per plant, and the other side branches and buds should be removed at any time. Loofah is the same as the male and female flowers, and the number of male flowers is large. In order to reduce the consumption of nutrients, more than 70% of the male flower buds can be removed in time. When going to the male buds, be careful to touch the female buds on the same node.
2, Yougua go to the inferior melon, each loofah in the different melon period only choose to stay in the melon 1 to 2, the juveniles that choose to keep the high-quality melon should be up and down, the strip straight, the stalk is thick and not slender, at the same time In the first few sections of the selected melon, a young melon is reserved to compete for nutrients. When the selected high-quality melon is long enough to not break, remove the front melon. The melons that are under the knot cannot be left on the top of the rack, and should be laid down in time. If the melon type has a bow shape, it must be straightened manually (a small stone can be hung on the flower bud).
3. The rational application of fertilization and topdressing plays an important role in the fruit setting and filling expansion of loofah. The application time, frequency and dosage of top dressing depends on the growth of loofah and the amount of melon: when the diameter of the first stage is more than 4cm It is necessary to apply the first top dressing, about 3 kg of pure nitrogen per mu (about 7 kg of urea); after 10 days, apply 4-5 kg ​​of pure nitrogen (about 10 kg of urea) to promote the expansion and enrichment of loofah. Afterwards, it will be applied once every 15 days, each time using 4 to 5 kg of pure nitrogen (about 10 kg of urea)
Note: The fertilization method should be mainly applied by pouring, and it should be applied alternately around 50cm of the base of the stem to prevent the near root from being damaged.
