Pumpkin is widely planted in our country, there are many varieties of pumpkin, pumpkin is eaten in a variety of ways, and it can also be used as green fodder for livestock and poultry. Of course, the more pumpkins you plant, the better, and the following management tips should be paid attention to in the management process, which can be more conducive to the pumpkin fruits.
1. Fertilization is less nitrogen, more phosphorus and potassium, pumpkin has a strong ability to resist diseases and pests, developed roots, strong stems and vines, thick leaves, once too much fertilizer and water, especially too much nitrogen fertilizer, it is easy to cause excess nutrition, resulting in the appearance of growth, and then causing reproductive growth lag, resulting in less flowering and less melon. Stop using nitrogen fertilizer when topdressing, apply phosphorus and potassium fertilizer appropriately, and at the same time, you can slow down the upward transport of nutrients and promote reproductive growth by pressing branches and vines and spraying plant growth inhibitors.
2. Reasonable pressing vine pruning to remove old leaves, during the growth of pumpkin, once there is growth, pumpkin seedlings form too large shade, the worse the field microclimate. The appearance of old leaves in pumpkin seedlings will also consume a lot of nutrients, and it is necessary to thin the old leaves from time to time to reduce nutrient consumption. At the same time of management, cut off part of the old leaves, remove the side vines in the axils of the male flower leaves, properly control the vegetative growth, turn to reproductive growth, and promote more flowering.
3, pumpkin side branches to go or stay, pumpkin according to the strength of growth to decide how to prune, to leave side branches, according to the actual situation of the operation, the planting is relatively sparse, the growth potential is weak, the side branches are relatively less pumpkin, you can remove the main vine top center, appropriately leave the side branches as fruiting branch culture, through the supplement of fertilizer, promote the growth of side branches and flowering and fruiting. When fertilizing, it is more conducive to the growth of pumpkin and more fruits.
4, pumpkin topping management, some pumpkin varieties melon characteristics is that the main vine is not as good as the sub-vine melon, therefore, for the large pumpkin with lush seedlings, it is necessary to remove the growth point of the vine in a timely manner, under normal circumstances, the main vine is about 1 meter 8 to two meters, the top growth point of the main pumpkin vine is removed, and the pumpkin side branches are promoted, which is conducive to increasing the number of pumpkins and increasing the yield of pumpkin.
5. Assist pollination and prevent melons;In order to improve the fruit setting rate of pumpkin, it is very necessary to carry out artificial assisted pollination, the female flowers of pumpkin and the male flowers are opened separately, in sunny days, the temperature is more suitable, there are insects can help pumpkin to complete pollination, but in case of continuous rainy weather, the activity of insects is affected, and it will also bring inconvenience to pumpkin self-pollination, and the use of artificial pollination can significantly improve the pumpkin setting rate. The method is to pluck the male flowers of the pumpkin when they are in bloom and buckle them directly to the flowers of the female flowers, so that they can help complete pollination. After successful pollination of pumpkin, the ovary of the female flower will expand rapidly, just after pollination, if it encounters rain beating, it is very likely to cause the female flower to appear melon, and the flower, in order to prevent the rain from beating, all the female flowers that are not covered by pumpkin leaves, should be covered with leaves, or other mulch, gently cover the female flowers that have just been pollinated, do not hurt the female flowers, even if it rains some time, it will not affect the normal growth of the female flowers, so as to improve the melon setting rate of pumpkin.
6, to prevent snail damage, pumpkin summer growth if it encounters more humid climatic conditions, easy to breed snails, snails like to gnaw pumpkin flowers and fruits, when the female flowers are harmed by snails, and easy to cause damage to detach, can be found after the snail, in the evening around the field sprinkled with tetraacetaldehyde, there is a better role in the prevention and control of snails. Well, that's all for the sharing of this chapter, welcome to follow, like friends who like it and then go.
