Cultivate weeds. Generally, after the planting has been planted with osmotic water, the first cultivating is carried out when the topsoil is slightly dry and not sticky. If there is a windy day or when the soil is dry, the water can be re-irrigated once and then cultivated. The second cultivator can be carried out 10 to 15 days after the first cultivator. The cultivator should pay attention to the protection of new roots and should not be too deep. Each cultivator can be combined with a number of high-quality farmyard fertilizers: such as cake fats, all kinds of bird hair, and decomposed chicken manure and pig manure. After the scaffolding, when the melon vines grow to more than 50 cm, the roots are basically covered with the entire line, and it is generally not appropriate to plough the vines. But pay attention to timely removal of weeds. In the first cultivator, if a seedling or a weak seedling is found, it must be planted in time to preserve the seedlings. Racking and pruning. When the seedlings grow to about 20 centimeters, they need to be crawled. There are two types of scaffolding: flat scaffolding and herringbone. The flat scaffolds are well ventilated and airy, produce many fruits and produce high yields. The flat scaffolding is divided into flat scaffolding and subdivision flat scaffolding. Lianping scaffolding is generally carried out in rows of melons. A wooden stake is erected every 3 to 4 meters. The wooden stakes of the whole field are connected to a small piece of bamboo, a small wooden stick or a nylon net. The roof is about 2 meters away from the ground. About meters; divided flat scaffolding is generally every two rows of melon as a shed, shed height of 1.5 to 2 meters. Straddles must be firm to prevent the wind from collapsing and damage the melon seedlings and affect the yield. In the early period, attention should be paid to artificially tying up vines and assisting melons to get on shelves. After the bitter gourd is put on the shelf, the main vine can not leave melons below 50 cm. The female flowers should be removed to facilitate the overall development. After the main vines sit 6 to 7 melons, leave 5.6 leaves to be topped and remove the rest of them. Fertilizer management. The bitter gourd grows for a long period of time and the collection period lasts for more than 3 months. Therefore, it is necessary to ensure adequate supply of water and fertilizers, especially during the full fruit period. In case of drought, water should be poured every 7 days. Before watering, it should be combined with urea or compound fertilizer 7 to 10 kilograms per acre, in case of continuous rain, should pay attention to row of phlegm; while foliar spraying potassium dihydrogen phosphate 2-3 times. Pest Control. Diseases of bitter melon mainly include anthrax, which occurs more than in the middle and late stages. Control should be promptly removed from the residual, rotten, diseased leaves. Can also be used 50% thiophanate 800-1000 times, or 70% of chlorothalonil wettable powder 600 times daily spray control in the early stages of the disease, insect pests mainly aphids, cabbage caterpillar, available enemy emulsion emulsion 1000 to 2000 times Liquid or 40% Dimethoate 1500 times foliar spray. Timely seed collection. The fruits of a bitter gourd are mature one after another. During the prosperous period of melons, mature melons should be picked once a day; use scissors when picking them to avoid tearing them. At the same time, we must eliminate the mixed melons, choose the color and melon-shaped preserved seeds, and do the picking on the same day, take the seeds and wash them on the same day to ensure the seed germination rate.
