When the main vine has 3-5 leaves, it should be topped. Both main vines and sunny vines can produce melons. Generally speaking, the production is mainly sun-dried vines and melons. Multi-vine pruning is adopted, that is, when the seedling has 4-5 true leaves, 4 true leaves are left for the main vine to core, and 3-4 strong main vines are selected after the secondary vine is elongated.

When it grows to 5-6 true leaves, the secondary vines should be re-cored, leaving 3-4 male vines in the whole plant. After the female flower appears on the rattan, leave 1-2 leaves before the flower to remove the core, and all other branches should be removed at the same time. Generally, 3-4 melons should be left in the whole plant.

Generally, melons bear fruit by vines and sun vines, but the main vines are difficult to bear fruit, so the main vines hit 3-5 leaves at most. If the 3-4 leaves of the vine have not yet borne fruit, they must be topped again, so that it can develop sun vines until the sun vines bear fruit. This is a mandatory topping method. In short, topping is for the result. Beat the fruit until it hangs.

It is advisable to leave 5-6 fruits per melon. In other words, one vine and two fruits. After the fruit is successfully hung, leave 5-6 nutritious leaves before the fruit, which needs topping. With those leaves, photosynthesis can also provide nutrition. In order not to lose, try to support the fruit, be sure to top it more to avoid nutrient loss of branches and vines. This is the biggest management difference between melon and watermelon.

Matters needing attention in melon seedling management:

1, temperature management In the stage from sowing to emergence, high temperature management should be done well to promote the growth of melon seedlings and reduce the nutrient consumption of melon seeds. It is advisable to control the temperature at 30 ~ 35℃ during the day and at 18 ~ 20℃ at night to ensure that the seedlings are neat and complete.

2. Pay attention to ventilation after emergence, do a good job in low temperature management, avoid excessive growth of seedlings, and also prevent the emergence of high seedlings. The temperature is generally controlled at 13 ~ 22℃. Before planting, in order to promote the growth of seedlings, the temperature must be increased to promote the differentiation of flower buds and the robust growth of seedlings, and the temperature should be controlled at 18 ~ 25℃.

3. Light management The light is weak in winter and spring, so it is necessary to use a transparent film when raising seedlings and keep the film clean, so as to improve the photosynthesis of seedlings and promote their growth. After the emergence of melon, the straw curtain must be uncovered on time to keep enough light as far as possible. If the seedlings have insufficient light, they should be shaded in time.

4. On cloudy days, in order to ensure the growth of melon seedlings, it is necessary to uncover the curtain reasonably to see the light, and the root water absorption and leaf transpiration water consumption of seedlings are unbalanced, which is prone to acute wilting. In this case, it is necessary to shade the seedlings, and when the seedlings return to normal, they will not wither when they see the light again.
