1. Variety selection The varieties of good bitter gourd suitable for greenhouse cultivation include: Sichuan Changbai bitter gourd, Hunan Blue Mountain bitter gourd, Jiangxi Yangzizhou bitter gourd, Ji'an white bitter gourd and so on.
Second, nurture strong seedlings
In mid-January, greenhouse electric nursery nursery, nutrition 钵 钵 root protection. Bitter gourd seeds have shell-like hard shell, need to use boiling water or warm water red seeds, stir until not hot, placed at room temperature (about 25 °C) soak for 24 to 28 hours, remove, wash, wrap, at 30 °C? The germination was carried out for 7 to 10 days under 35°C conditions. Every 667 square meters (1 acre) of greenhouse need about 200 grams of seed.
Third, colonization
When there are 4-5 leaves in the middle and late February, they are planted on a sorghum 1.2 meters wide in Liangou, planted one row with a spacing of 0.5 meters and planted 1,100 plants per 667 square meters.
IV. Management after planting
1, greenhouse control temperature and humidity after planting closed seedling greenhouse temperature to promote the slow Miao. The antifreeze should be warmed before the end of March and be properly ventilated during the day. Before the end of April, pay attention to insulation at night and pay attention to ventilation and humidity during the day. After May, ventilation and cooling were the main factors. Ventilation began when the temperature reached 30°C in the afternoon and stopped when the temperature in the afternoon shed fell to 25°C. In June, the greenhouse undercover membrane was removed and the roof membrane was kept rainproof.
2, fertilizer and water management bitter gourd hi fat and wet, under the condition of adequate water and fertilizer yield, good quality, based on the application of base fertilizer, fertilizer and water management must also be strengthened. Although the bitter gourd is resistant to fertilizer, but the seedling stage has weak fertility, a little thicker fertilizer will burn the seedlings, how to prevent and treat the brown spot on the bitter gourd? Therefore, it is necessary to pay attention to lighter weight and higher weight. After transplanting, 10% diluted manure water can be used in the seedling stage, and 1 to 2 heavy fertilizers are applied during the vigorous growing stage and flowering stage of the stems and leaves, and 25 to 30 kilograms of compound fertilizer is applied every 667 square meters. Once harvested, topdressing once with a mixture of 0.2% urea and 0.3% potassium dihydrogen phosphate. The characteristics of water management are: After the seedlings grow slowly, they can properly control the moisture and keep the soil moist. In the rainy season, drainage should be cleared in time.
3, pruning, erecting bitter gourd branching, greenhouse cultivation density, more likely to produce vine leaves too dense, poor ventilation and light, empty nutrient consumption, affecting the yield and commodity. Therefore, it is necessary to strengthen the pruning and cultivate it with a stand. When using vines and tendrils, take the trusses or arches and trapezoidal frames in time to introduce vines to the shelves. The main bitter gourd is dominated by vine vines. Side vines must be removed. Under the condition of sufficient fertilizer and water, several side vines can be left in the later period. The four advantages of the Shouguang New Rural Bitter Gourd are to increase the later yield. At the same time, old leaves and diseased leaves should be removed at any time in the middle and late stages of production to facilitate ventilation.
4. Artificially assisted pollination. Due to the low temperature of early ripening bitter gourd, open sheds, low air flow in the shed, and low insect pollination, natural pollination is difficult, so artificial pollination, and use 20-40 mg / l 2,4 D smear female pedicels or young Melon, in order to increase the fruit-bearing rate of bitter gourd, to overcome the melon, promote melon expansion, increase production.
