celebrity style jewelry wholesale The use of greenhouses such as greenhouses and other protective watermelons has now formed a large scale in Shanghai, Zhejiang, Shandong, Beijing and other places. In recent years, in the southern provinces, especially the Yangtze River Basin, it has also begun to introduce, research and promote, and has produced good economic and social benefits. For example, the common "early spring red jade" watermelon on the market is sold in most large and medium cities across the country, which is favored by consumers. The use of greenhouse cultivation grooves in the early spring is a good way to create income and increase efficiency.

Construction of greenhouses. The first role of watermelon cultivation in the southern greenhouse is rainproof, followed by heat preservation. Watermelon is most afraid of too much rain, and the south, especially in spring and summer, has many rainwater, which causes the watermelon production in the area to be unstable. The use of greenhouses to cover rain -proof cultivation can better solve this problem. The plastic greenhouse should be built on the land that is high, easy to drain, sunshine, and suitable for planting watermelon. It is better to use rice fields and have not grown melon for many years. Generally, it is appropriate to set up 7-8 meters width, 25 to 30 meters long, and 2 to 2.5 meters high. Bamboo sheds, cement sheds or steel sheds can be used. This kind of cultivation form is large, and the land selection is the key. Generally, the same location should be planted for only 1 year. The next year should be replaced with a suitable plant for many years without planting. performance.

variety selection. Watermelon cultivation in early spring should choose high -end varieties to achieve the purpose of high -end, high -quality, and high benefits. At present, the most widely used varieties in production are early spring red jade. Other varieties include early, Xiaolan, Xin Jinlan, Xiuli, Xiuya, Bingjing, Hua Mei, Red Xiaoyu, Huang Xiaoyu and so on.

Early seedlings are the basis of this technology. Generally, seedlings should be carried out from January to February before and after the Spring Festival. The nutritional bowl is concentrated in the seedling of seedlings, with multi -layer coverage, and should have insulation and freezing facilities, such as geothermal lines and high -power light bulbs to facilitate germination and sowing, produce seedlings as soon as possible, and reduce the chance of freezing damage. From January to March, the temperature of the Yangtze River Basin is relatively low, and there are often cold flows. When the watermelon seedlings are raised, the seedlings are most likely to cause freezing damage to the seedling stage, especially for planting to the seedling stage. It is dangerous in 1 to 2 days below 10 degrees. Or use heating protection facilities. In addition, the drying of the seedbed and nutritional soil as much as possible is also an effective measure to improve the ability of cold resistance. In order to promote the growth of seedlings, pouring fertilizer water must be carried out on a sunny day. After 1 to 2 days after pouring, the nutritional soil becomes dry, which facilitates the ability of the plant to resist cold and disease.

covered. Early spring cultivation is generally covered with 3 layers, namely greenhouses, small arch sheds, and ground membranes. The geosterite is fully covered, and its advantage is that the preservation performance is enhanced, not long weeds, watermelon vine leaves and fruits do not stick to the soil, fat water perfume subfamily, reduce the infection of pests and improve the appearance of the fruit.

The fertilization. Due to the full coverage of the ground membrane and the relative difficulty of topdressing, sufficient base fertilizer must be applied before planting. Bida fertilizer is suitable for delayed fertilizer such as cake fertilizer, livestock fertilizer, soil miscellaneous fertilizer, potassium sulfate compound fertilizer, etc., but it must be fermented, and the rapid efficiency is applied. Watering and topdressing uses subfamily drip irrigation, that is, the drip irrigation pipe is set up at 50 cm in the front of the cover film. After the fertilizer is fermented, soaked, and filtered, drip irrigation is conducive to protecting watermelon vine leaves and fruits. After each picking a batch of melons, pursue it in time to facilitate continuous fruit.

plant and fruit management. When the plant is as long as 1 meter, a whole pruning is performed to ensure 2 to 3 fruits per plant at a time. Generally, the whole branch of the afternoon is selected to avoid breaking and damaging the vine leaves, which is conducive to wound healing and reducing disease infection. In the early spring, due to low temperature and less insects, it is difficult to sit in melon. Measures such as artificial pollination and bees can be used to promote the fruits. In order to improve economic benefits, you can also sit on the market with low -saving. Defensive melon and cracks are removed in time. Small watermelon is generally good quality. Eight mature has high quality. Especially in high temperature season, it can be mature for more than 20 days after sitting. For long -distance transportation, carton packaging should be used to avoid cracks.
