Cultivation points
1. Sowing and raising seedlings: Candied seeds can be planted in Guangzhou from December to September of the following year. Seeds soaked in seed germination or transplanted after seeding, and the temperature in early spring is relatively low. Small-scale sheds and other cold-proof measures should be adopted to raise seedlings.
2. Site preparation and site selection: It is best to choose a loam soil that is not a melon crop, has good drainage, and is rich in organic matter, and has a 1.8-meter wide ditch. It is better to go north-south and east-west.
3, transplanting seedling colonization: When the melon seedlings grow to 2-3 true leaves can be transplanted, colonization specifications for the 0.7--0.9 meters, a single line plant.
4, fertilizer and water management: winter melon needs a large amount of fertilizer, should be enough base fertilizer, Mushi organic fertilizer 1500-2000 kg, 30 kg of peanut bran, calcium superphosphate 30 kg, after every 7-10 days after planting a thin application of nitrogen fertilizer, knot When the weight of melon melons reaches 4--5 kilograms, topdressing should be repeated, 40-50 kilograms of compound fertilizer can be applied to Mushi and 60-80 kilograms of peanut bran. The melon fertilization should be applied thinly, before light and heavy, with a reasonable mix of nitrogen, phosphorus and potassium. After the melon vines are put on the shelf, the water requirement is gradually increased. Attention should be paid to frequent watering and keeping the soil moist. Care should be taken during the rain to remove stagnant water in order to prevent water accumulation.
5, the whole vines pressure vines: the main vine pods, should be removed in time vine side, all the side vines before removal of fruit. Put the main vines in the circle of the plant spacing before the shelves, pressure vines once every 3-4 times, a total pressure of 3-4 times, promote the formation of adventitious roots, to around the 16-18 Festival when the introduction of vines. The scaffolding method includes the scaffolding method and the dZi dragon-root method. In Guangzhou, the dZi dragon-root method is used, and 3 or 4 bamboo rafts are used to form a drum frame. A bamboo raft on the horizontal plane is used as a dragon root. When the wax gourd grows to 3--4 kilograms, the cucurbit handle is covered with hemp rope and tied to the dragon root of the drum frame. About 15 knots after the melons were topping.
6, stay melon: generally in the 25-32 section, the main vines in the first 3 - 4 female flowers to stay melon is the most ideal. In case of bad weather during fruit set, artificial pollination should be conducted early in the morning to increase the fruit setting rate, and the fruit setting rate can also be improved by using anti-dropping agents. The selected juvenile melon should be cylindrical, uniform in size, wide and flat in shoulder, top in pure circle, full of hair and shiny. After selecting the good melon, the remaining baby should be removed promptly.
7. Pest control: The main diseases are wilt disease, epidemic disease and anthrax, which can be controlled by using 800 times of chlorothalonil, 500-800 times of thiophanate, and 3000 times of No.1 Greenhenge. The main pest is Thrips, which occurs most severely from late July to September at a temperature of 25-30°C. Prevention and control should be sprayed in a timely manner 1000 times Bataan, double 400-800 times insecticide, 20% Kang Fu more than 6000-10000 times EC, 5% efficient large hero 2,500 to 3000 times the liquid, spraying every 5-7 days One time, the medicine should be used alternately.
8. Harvest: Generally about 60 days after the fruit is set, the epidermis is bright and can be harvested when it is dark green. If the harvesting is too late, the nutrients of the fruits will be transformed, affecting the quality of food and timely harvesting.
