The high yield of watermelons that you want to grow is what everyone wants. So, do you know how to increase the fruit setting rate of organic watermelons? What are its specific management methods? Let's let Xiaobian introduce it to everyone.
How can we improve the fruit setting rate of organic watermelon?
Adjust the sowing date: organic watermelon cultivated in the open field, according to the local climatic conditions, appropriate early or delayed sowing, so that the melon period avoids the rainy season, in order to facilitate pollination and fertilization, thereby increasing the rate of sitting.
Artificially assisted pollination: During the open period of the second and third female flowers of the main vine, in the sunny morning of the flowering period, the male flowers are taken and the petals are peeled off. The female flower stigma is gently applied with anthers; in the rainy days, the female flowers are covered with a small plastic tube or paper bag to protect the rain. , for artificial pollination. According to the test, the artificial assisted pollination can increase the sitting rate by more than 10% when the natural pollination is no wind on sunny days, and the sitting rate can be increased by more than one time in the rainy days.
Packing: When the organic watermelon grows to 4-5 pieces of true leaves and there is no growth of cockroaches, use a shovel to smash down 13 cm away from the melon root. The deeper the better, the deeper the shovel and the plow. But can't damage the main root. This is not to turn the soil up, but to smash the ground. In this way, the vegetative growth of the plant can be inhibited, and the slenderness and stem stalks can be prevented from being slender, and the roots can be grown vigorously, forming a large root system, which is favorable for flowering and sitting.
Jiagen: It is also called Jiagen Jushui. The practice is: when the second and third female flowers of organic watermelon appear, put two 17-cm long wooden strips in the oil pan and fry them, then one finger away from the ground. In a high place, the clip is clipped to the extent that the melon root is flat but the grain is constantly suitable. In the future, a shackle is formed in the folder, and the melon is not only stable but also grows large.
Squeeze the stem: squeeze the stalk on the back of the young melon and hear a "click", so that the young melon can sit stably and prevent the melon. It is this truth that melons are "after the head, sitting in front of me."
The above is the improvement method of the organic watermelon fruit rate introduced by Xiaobian for everyone. Do you understand? I hope that the Xiaobian article will help everyone to grow watermelon better.
