Kind of late winter melon has good economic benefits
The late melon generally has a yield of more than 4,000 kilograms per mu, which is suitable for fresh storage after the fall and has a higher market efficiency. However, because the growth period is in the high temperature and high humidity season, the contradiction between the supply of water and fertilizer and the growth and development are aggravated, especially the pruning or not, which is the key to the high yield of melon products. 1 The field selection of wax gourd should not be planted continuously in the same land, nor should it be planted on low-lying land. More fertile and neutral soils should be chosen for cultivation. Late winter melons are generally sown in June-July, and about 200 grams per mu are used. 2 Transplanting when the age of the winter melons reached 30 days, and when they grow two leaves and one heart, choose the root system developed, the thick section of the stem is short, the thick and thick leaves, and the seedlings without damage are transplanted. Generally only the main vine, acres planted 800 - 900, leaving two vines cultivated, acres planted 400 - 500. 3 Reasonably top-dressing the late winter gourd's top dressing principle is “pre-light, heavy-duty, and late-supplementâ€. After the seedlings are planted and lived, they recover about 100% of 20% human excreta. When the melon grows to 4-5 kg, the points are reclaimed from the excrement of urine 4-5 kg ​​or urea 0.10 kg; when the melon grows to 15- At 20 kilograms, acupuncture points to recover human excreta 5--6 kg or urea 0.20 kg. If the leaf color fades afterwards, fertilizer can be applied to 2--3 kilograms of human excrement per litter. The cultivators were cultivated once when the melons grew to 1 meter in length. 4 Pruning and pruning is an effective measure to increase output, control slenderness, and ensure consistent size of melons. Usually leaves the main vine cultivation, when it grows to 20--24 leaves, began to stay in the melon, the former melon should be removed; leave the main vice vine cultivation, the main vine to stay in the same position; the side of the vine can not be less In 10 leaves, all the branches of the young larvae were cut off to facilitate the growth of nutrients for the growth of the young larvae. 5 Artificial pollination assisted pollination can increase fruit setting rate. Select the male flower that has just opened in the morning to remove the corolla and gently apply the anther to the female styling head. 6 The main diseases and pests of Pesticide Night Papaya are damping-off disease, blight disease, epidemic disease and aphid and mite. Resistance to phlegm can be controlled by 75% chlorothalonil 1000 times solution or 70% dexamethasone WP 1000 times solution; 50% carbendazim 500 times solution or 900 times 20% chlormethestin can be used to prevent fusarium wilt Liquid control; Epidemic disease can be used 75% chlorothalonil 600 times or 50% methemosulfide wettable powder 600 times sprayed leaves or irrigation roots, per plant irrigation 0.30 - 0.50 liters, irrigation 10 days or so, even prevention 2 - 3 times the effect is good; anti-worm can be used 40% dimethoate 800 - 1000 times or 90% crystal trichlorfon 1000 times. For control of earthworms, 50% phoxim 1000 times liquid or 1000 times liquid trichlorfon root can be used. China Agricultural Network Editor
