The solution to the low setting rate of watermelon

Watermelon is the most popular fruit in summer, bright red flesh, delicious juice, old and small, and in watermelon planting, often sit melon rate is low, which not only affects the growth of watermelon, but also affects the yield, reducing the economic income of melon farmers. So what about the low watermelon sitting rate? How to solve it? Let's take a look.

1. Strengthen fertilizer and water management

Fertilizer and water management have certain influence on watermelon sitting rate, especially before and after flowering, watering should be controlled during flowering period, watering according to soil humidity, so as to keep soil slightly moist. To the fruit expansion period, for the rapid increase in water, then need timely irrigation. There are timely topdressing fertility, pay attention to the reasonable combination of nitrogen, phosphorus and potassium fertilizers, but also pay attention to the application of other trace elements, so as to ensure the normal growth of planting and improve the rate of sitting melon.

2. Pruning and pruning

Watermelon is a vine plant. In order to make it convenient to manage and improve the sitting rate, when the main vine grows to 120-150cm and the seed vine grows to 50cm, it needs to be pruned. Only the main vine and 2-3 strong growing sub-vines are preserved, and the rest of the sub-vines are all cut off, so as to avoid excessive consumption of nutrients, concentrate the supply of nutrients, and promote early flowering. During flowering, the seed vines sprouted before and after female flowers are slowly cut off, which can greatly improve the sitting rate.

3. Artificial pollination

Watermelon is pollinated by bees and insects, but pollination will be affected if other factors, such as low temperature, long-term rainy season and so on, lead to fewer bees and insects or weak activity. Therefore, artificial pollination is an important point for high sitting rate. When flowering, remove the male flower when it opens, remove the corolla, expose the anther, use cotton swab or toothpick to take pollen and gently smear it on the stigma of female flower, and see that the stigma turns yellow, that is, pollination is successful. In case of rainy days after pollination, protective measures should be taken to avoid pollination failure caused by rain or flower and fruit dropping.

4. Pest control

Diseases and insect pests can also affect the rate of watermelon sitting, such as common anthracnose and blight, which harm fruits and leaves, cause leaves to wither and fall when they occur, and cause plant death when they are serious. Strengthen field management, especially in high temperature and rainy season and disease onset period, drainage measures should be taken, ditch drainage should be carried out in time, diseased leaves and diseased fruits should be removed in time when disease occurs, and then pesticide control should be carried out.

The above is the solution to the low watermelon setting rate brought by the parent farming network. Spraying gibberellin solution during planting can significantly improve the watermelon fruit setting rate and sugar content. I hope it can help you.
