The regenerating cultivation of watermelon, that is, using the old plant regeneration technology, results in the second time the watermelon. In this way, it not only solves the problem of replanting watermelon or the difficulty of raising young seedlings in the autumn, but also adjusts the watermelon in the city. Practice has proved that the reclaimed watermelon can generally be harvested in about 50 days. The yield and quality are comparable to that of the head loquat watermelon, but the economic benefits are doubled. The operating points are:
The best watermelon varieties suitable for regenerating cultivation include Xinhongbao, Japan Jushi and Xinzheng Hybrid No.5 and No.9. When the heads of cucumbers are stable, timely application of organic manure as the main fertilizer supplements the expansion of the melon fertilizer, timely watering in case of drought, to meet the nutritional needs of the head lice and young larvae, and second, to lay a foundation for the regeneration of new vines. basis. At the same time, we must pay attention to the first 7-10 days before harvest, with 1500 kg of decomposed manure, 50 kg of compound fertilizer and 50 kg of cake fertilizer. The holes are applied to the plants and are conducive to sprouting.
After harvesting the head loquat watermelon, all fields are cut and vines are immediately cut, leaving about 10 cm of old vines at the base of the old plant. When the plant's base regenerates sprouts, it can be combined with clear gardens to carry out cultivator weeding and leave 3 robust and fresh vines per plant. When most of the new vines grow to more than 30 centimeters, 15 acres of urea, 25 kg of phosphate fertilizer and appropriate amount of cake fertilizer are poured into the soil to promote the regeneration of new vines and robust growth. In order to prevent the regenerated plants from growing in length, one or two chlormequats can be sprayed on the growth of the plant, and a 0.2% potassium dihydrogen phosphate solution is sprayed every 10 days. At the same time, watering and drought resistance, artificial pollination, pruning, prevention and control are performed. The work of pests and other methods is basically the same as that of the head. After the young melons have settled, a few drops of vegetable oil are added to the rhizomes of each melon to improve the fruit quality. After about 50 days, it is harvested and listed.
