The varieties cultivated in greenhouses are mostly early-maturing varieties, which creates time conditions for watermelons to recolonize. According to the experiment, after the current picking of watermelon, the old vine can be grown after cutting off the old vine 7-10. The second pod can be harvested in 40-45 days, yielding about 1,000 kilograms per mu. The benefit is considerable. 1, cultivate new vines The melon should be cut again for the vine to be harvested. After harvesting, the old vine should be cut 30-35cm away from the root, and the latent buds after using the base leafhopper should germinate after germination or remain at the base of the old vine. 2 robust new vines, the rest cut off. In this way, the position of the melons is low and the vines grow rapidly and vigorously. The watermelon has a fast maturation, a large melon, and a high yield. It is 500-600 kg higher than the other methods. 2. High-yield measures (1) Protect the root system. In the management process of fertilizing, watering, and weeding of the former gourd, we must carefully and carefully protect the root system so that the root system is not damaged, and it can grow normally and robustly. (2) fertilizer and water management. The former pods were applied with a single available nitrogen fertilizer 3 days before harvest, generally 15-20g urea per plant. The watermelons are watered promptly after harvest to promote the growth of new vines, expand the leaf area, and create conditions for the melons. When the plants have 80% of them sitting, apply fertilizer once more, generally applying 10 kg of potassium sulfate, 10 kg of potassium dihydrogen phosphate, 5 kg of urea or 500 kg of fully-fertilized organic fertilizer, and 20 kg of compound fertilizer. (3) Clearing the garden and preventing the disease, after harvesting the melons, clean the field weeds, rotten melons, diseased plants, residual leaves, and leftover melons in a timely manner, and spray 2-3 500 times of carbendazim or 600 consecutive times. Betacrotoxin and 0.2% urea prevent disease. The old melons that are cut off must be transported out of the field in time and the melon fields should be cleaned up. (4) New twigs, generally using a method to leave a melon, because the plants cut to old vines, new vines strong, fast, and many results. In order not to affect the normal growth of the melons, the rapid expansion of the melons and their early maturation will be cut off. (5) Other management is like conventional cultivation.
