Management of flowering and fruiting period of Pumpkin

Pumpkin flowering and fruiting is from reproductive growth to vegetative growth, which is the key to determine the yield. In order to improve fruit setting, it is necessary to prevent falling flowers, but also to sparse their own flowers and decide to keep flowers. After the fruit, the fruit should also be thinned to ensure the growth of high-quality fruit and stay in the right position. So we have very important work to do during the flowering and fruiting period.

1. Fertilizer control and water control

Pumpkin does not need to be watered except in case of drought, except that pumpkin is watered with fixed root water when planting and slow seedling water when slowing down seedlings. Fertilization is mainly after the fruit, mainly phosphorus and potassium, basically no nitrogen fertilizer, the plant grows vigorously in the fruiting period, the application of nitrogen fertilizer is easy to break the balance of vegetative reproductive growth. Topdressing is about 50 jin of compound fertilizer per mu.

Second, regulating growth

The main reason is that when the fruit amount reaches the standard, the terminal bud growth point on the vine will be removed after the result is stable, and the core will be removed to prevent the vine from continuing to grow and bear fruit, resulting in the retention of fruit nutrition is not enough and fall off. In the prosperous growth, the excess branches should be removed before the fruit, and the unfruitful branches should be removed to avoid wasting nutrition. Remove the old leaves to prevent diseases and insect pests, ventilation and light.

III. Artificial pollination

In order to ensure the development and fruit of adzuki bean and prevent natural pollination from being not in place, pollen can be collected manually and then pollinated artificially when there is no wind in the sunny evening. Meticulous collection and tool pollination can be carried out, or male flowers can be pollinated directly to female flowers in the right weather. In the future, we can observe the results and then decide whether to make up for it or not.

IV. Prevention of diseases

The main diseases in flowering and fruiting period are aphids and red spiders. Aphids harm a variety of vegetable crops. Adult piercing and sucking leaves may cause the leaves not to produce normal light and function to produce nutrients to provide fruit, larvae can eat the fruit to cause damage, like red spiders mainly prick and suck juice harm. Therefore, if you want to prevent it first, you should use medicine to control it as soon as you find it. General use of imidacloprid, acaricide to control, a variety of pesticides can be used alternately to prevent drug resistance.

The flowering and fruiting period of pumpkin is the most important period in the whole growth period, and it is easy to have many problems, so we should use some methods to adjust the growth balance of pumpkin to ensure the yield.
