Greenhouse regeneration watermelon cultivation techniques
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. The cultivation of new mango cultivars should be followed by cranberry regeneration. After harvesting the head lice, cut the old vines 30-35cm from the roots, use the latent buds of the base leafhoppers, germinate, or vines. The base stays 1-2 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 to prevent disease. After harvesting, the melons were cleaned in time, field weeds, rotten melons, diseased plants, residual leaves, and leftover melons were sprayed, and sprayed 2-3 times with 500 times carbendazim or 600 times chlorothalonil and 0.2% urea. To prevent diseases. 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) Fresh pruning. Usually a method of leaving a melon, because the plant to cut the old vine, the new mango 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.
