The latest solution to the low setting rate of watermelons

Watermelon is the most popular fruit in summer, with bright red flesh, delicious and juicy, suitable for all ages, but when watermelon is planted, the setting rate is often low, which not only affects the growth of watermelon, but also affects the yield and reduces the economic income of melon farmers. So what if the watermelon sitting rate is low? What should we do about it? Let's take a look.

1. Strengthen the management of fertilizer and water

Fertilizer and water management has a certain impact on the setting rate of watermelon, especially before and after flowering, it is very important to control watering, watering according to the soil dry humidity, so as to keep the soil slightly moist. When it comes to the fruit expansion period, the moisture content increases sharply, so it needs to be irrigated in time. There is also timely topdressing fertility, pay attention to the reasonable collocation of nitrogen, phosphorus and potassium fertilizer, 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 melon setting.

2. Pruning and pruning

Watermelon is a vine plant, in order to facilitate its management and improve the setting rate, pruning and pruning is needed when the main vine grows to 120-150cm and the seed vine grows to 50cm. Only the main vine and 2-3 strong sub-vines are preserved, and the rest of the sub-vines are all cut off, which can avoid excessive consumption of nutrients, concentrate the supply of nutrients and promote them to blossom and bear fruit earlier. During flowering, the seed vines sprouting before and after the female flowers are slowly cut off, which can greatly improve the melon setting rate.

3. Artificial pollination

Watermelons are pollinated by bees and insects, but pollination will be affected if there are few or weak activity of bees and insects due to other factors, such as low temperature and long rainy season. Therefore, the use of artificial pollination is an important point of high melon setting rate. During flowering, remove the male flower when it blooms, remove the Corolla, expose the anther, gently apply pollen to the female flower stigma with cotton swabs or toothpicks, and pollinate successfully when the stigma turns yellow. In case of overcast and rainy days after pollination, protective measures should be taken to avoid Rain Water causing pollination failure or causing flower or fruit drop.

4. Pest control

Diseases and insect pests can also affect the setting rate of watermelons, such as anthracnose and Fusarium wilt, which harm fruits and leaves, cause leaves to wither and fall, and seriously lead to plant death. To strengthen field management, especially in the high temperature and rainy season, when the disease occurs, drainage measures should be taken, ditches should be opened in time for drainage, diseased leaves and fruits should be removed in time, and then chemical control should be sprayed.

The above is the solution to the low watermelon setting rate brought by the pro-agricultural network. Spraying gibberellin solution during planting can significantly improve the fruit-setting rate and sugar content of watermelon. I hope it can help you, more agricultural knowledge, please pay attention to the pro-agricultural network.
