Adjust the sowing date Artificial pollination During the opening of the second and third female flowers of the main vine, in the sunny morning of flowering season, the male flower is taken off to strip petals and gently apply the female styling to the flowers. On rainy days, the female flowers are rain-proofed with a small plastic tube or paper bag to open the artificial pollination. . According to experiments, artificially assisted pollination can increase the rate of sitting nectar by more than 10% on a sunny day without wind, and increase the rate of squashing on a rainy day by more than 1 time. Packing When the watermelon grows to 4-5 true leaves and there is no growth, use a spatula to straighten it down 13 centimeters away from the root of the melon. The deeper the better, you can also use the spade and plow to deepen, but do not damage it. The main root, this is not to turn the soil up, but to take a look at the earth. In this way, the vegetative growth of the plant can be inhibited, the leggy and stem vines can be prevented from being slender, the fibrous roots can grow robustly, and a large root system can be formed, which is conducive to flowering and sitting on the melon. Clip root Also known as rooting water, the practice is; when the second and third female flowers of watermelon appear, two 17-cm-long wooden sticks are blown in a pan, and then the melon root points away from the ground.ç‹ ç‹ å¤¹ 夹 夹 夹 夹 夹 夹 夹 夹 夹 夹 夹 夹 夹 夹 夹. In the future, it forms a skeleton in the folder. Not only does the melon sit steadily, it also grows. Pinch Put a pinch on the stalks behind the young squash, and hear a “kappa†sound, so that the young squash can sit steadily and prevent chew. The Gualou "Kaibu behind, sitting in front of the melon" is this truth. Functional oligosaccharides refer to oligosaccharides that are difficult or impossible to be digested and absorbed by the human body and have special physiological effects on the human body. Its sweetness is generally only 30-50% of that of sucrose, and it has physiological functions such as low-calorie, anti-caries, prevention and treatment of diabetes, and improvement of intestinal colony structure. Due to the special physiological functions of functional oligosaccharides, it becomes a nutrient and health care product. A new generation of food-effect raw materials that integrate diet and therapy. It is a new functional sugar source that replaces sucrose and has a wide range of uses and application prospects. Common functional oligosaccharides include: xylo-oligosaccharides, fructooligosaccharides, galacto-oligosaccharides, isomaltose, raffinose and so on.

The watermelon cultivated in open field, according to the local climatic conditions, should be sowed ahead of time or postponed so that the melon period avoids the rainy season so as to facilitate pollination and fertilization, thereby increasing the rate of sitting.
