Small watermelon climb cultivation

Early spring cultivation of small watermelon, there are generally two kinds of cultivation methods of stand cultivation and climbing cultivation. The shelf-grown melon yield is high, and the commodity is good, but the management requirements are fine; while the cultivation of the melons cultivated on the ground is slightly lower, the commodity is less, but the management is more labor-saving, both have their own advantages. The cultivation techniques of small watermelons are now described as follows: Species selection. As a gift-type high-grade small watermelon, it requires single fruit weight 1 to 2 kg, skin thickness 0.5 cm or less, beautiful pattern, soluble solids content of 11% or more, no seeds or less seeds, meat tender and refreshing, red peony or jaundice, easy Fruit set, suitable for greenhouse cultivation. Available varieties are early spring red jade, Xiang Yu ice crystal, Xiang Yu Huang Meiren, Xiang Yuhua beauty, Hong Xiaoyu. Cultivation methods. Whether it is a stand cultivation or climbing cultivation, it is best to use greenhouse facilities. The advantages of greenhouse cultivation: One can mention the morning market and extend the autumn supply period. Two can shelter the rain. Watermelon is most afraid of rain. After rain cultivation, the small environment is greatly improved, the fruit setting rate is significantly improved, the inner quality is improved, and the appearance becomes more beautiful. Three can reduce the spread of pests and harm. After the greenhouse is fully covered (in the high temperature season, the skirt film can be used as an insect net), it is isolated from the outside world, and the external pests are difficult to pass in and occur. Even if they occur, spraying the medicine can maintain the efficacy for a long time and produce no pollution in the fruit. There is a certain meaning on it. Sowing date, planting. Generally, the nursery will begin in Changsha in February. Nursery should be covered in multiple layers in greenhouses or greenhouses. Electric wires, light bulbs, or other heat sources are used as protective measures to open in time when the cold wave comes. The land where watermelons are to be cultivated should be land that has never been cultivated for many years (more than 6 years in paddy fields). Applying basic fertilizer before planting, the basic fertilizer is based on delayed organic fertilizer, such as 100 to 200 kg per acre of vegetable cake, 100 to 200 tons per mu after composting, and organic fertilizer is the best for potassium sulfate compound fertilizer. Each mu of 50 to 100 kg, the amount of application should be based on the situation of the land and fertilizer type and ratio of comprehensive consideration, in principle, the fertilizer is applied once, in the future generally no longer fertilize or little fertilization. The method of application is concentration of acupoints or strips applied to planting points and planting trenches. Top dressing is usually done with foliar fertilizer or combined irrigation. Film full coverage, film placed under a plastic tube or hose, every 0.5 to 1 meter to open a small hole, to prepare for later irrigation and fertilization, its advantage is that water and fertilizer does not stick leaf stem, immobile film to help insulation. The planting density is 500-600 plants per acre, and two rows are planted in the greenhouse. The size of the greenhouse is usually 5 meters (20-30 meters). The general colonization period was early in March, sunny days transplanting, a small arch shed after transplanting, three membrane coverage. Plant management. During the seedling stage, heat preservation promotes the growth of the seedlings. In the seedling stage, the water is poured into the soil in sunny days to promote growth. The adult plants can be fed through plastic pipes or hoses. Under normal circumstances, no pruning is necessary. Only when the leaf surface index (sum of blade area: land area) is greater than 2.0, proper pruning can be performed. After each batch of melons was picked, foliar fertilizers were sprayed and thin fertilizers were applied together with irrigation to ensure the growth and development of the next batch of fruits. Small fruit type watermelon has strong performance in continuous fruit setting. As long as the plant maintains a good condition, it can continue to produce results 4 to 5 times until November. One of the reasons is that the small fruit type watermelon is light and each fruit needs nutrients. Relatively few, the average number of fruit per plant is 5 to 10, according to 4 to 5 batches of fruit. Fruit management. The most important part of fruit management is fruit setting and seed removal. The cultivation of small fruit seedless watermelons requires less cultivation due to the need for high temperature and low fruit setting rate. The majority of cultivated watermelons are seeded small watermelons. However, seed consumption is inconvenient, quality is reduced, and the value is not high. Therefore, seed removal is a key technology for this type of cultivation. At present, the method used is to spray the young squash on the day before or on the day of the opening of the female flower. The first effect is that after spraying, the watermelon will be seedless, and on the other hand, it will be seedless. Promoting fruit setting, accelerating the growth and development of young melons, overcoming the phenomenon of low temperatures and rainy weather, melons and other phenomena, sweetening, improving quality, mentioning the morning market, and improving commodity value. Pest control. Relative to open-growing watermelon, greenhouse cultivation of watermelon pests and diseases due to membrane isolation occurs less, prevention and control is also easier. It is mainly prevention. After each spraying, it is sealed, so that the efficacy can be sustained and the control effect is better.
