Sunlight greenhouse cultivation of wax gourd in winter, 9-10 months of the seedling period, colonization period of 10-11 months. The melon melon has a longer growth period and better management during the seedling period. The pre-reproductive period is mainly in the severe cold season. The temperature and lighting are poor, and the technical difficulty is high. Various measures must be taken to increase the temperature and brightness and promote fruit setting; after March, the temperature The recovery, temperature and light conditions are suitable for the growth of wax gourd. It is necessary to strengthen the management of fertilizer and water, promote plant growth and fruit setting, and increase yield.
1, species selection. In order to use small fruit-shaped long-cylindrical melon varieties, such as Beijing bells and other early-maturing varieties.
2. Requirements for solar greenhouses. As wax gourd requires higher light temperature, energy-saving solar greenhouses with good structural and scientific insulation properties must be used. The extreme minimum temperature in the greenhouse should not be less than 6 degrees.
3, nurturing strong seedlings. The use of nutrients for mulching roots is usually about 40 days in seedling age, and 3-4 true leaves are planted. The environment of this wax gourd seedling is better, which is conducive to the cultivation of strong seedlings.
4. Site preparation. Based on the long-term growth characteristics of the wax gourd, it is necessary to finely prepare the soil and apply a large amount of high quality basal fertilizer. It is required to apply 6,000 kg of high-quality organic fertilizer per acre, and apply 40 kg of diammonium and 100 kg of superphosphate at the same time. The basal fertilizer was applied to the first half and the other half concentrated on the furrow. The colonization density is 75 cm and 40 cm. Colonization and covering with the size of the mulch, gingival sulcus is not covered with film, reserved for irrigation fertilizer.
5. Management after planting. In the initial stage of planting, we must pay attention to heat preservation to promote seedlings, combined with air release and fertilizer and water management, and promote rapid and robust seedling growth and fruiting. The period from the end of December to the beginning of March is the period when the outside temperature is the lowest. The key is to keep warm and improve lighting conditions, and combine various measures to promote fruit setting. To properly reduce watering, so as not to reduce the ground temperature, can be poured 15 times a day or so water, watering should be selected for continuous sunny morning, this time to reduce the air release, generally at noon to vent, its purpose is not cooling, but put Humidity and gas exchange. From the beginning of March, the temperature rises to strengthen the management of fertilizer and water, and increase the number and quantity of watering and fertilization. Since there is no insect pollination, artificial pollination or hormone treatment is necessary to promote fruit setting. Generally, the effect of artificial pollination is better than hormone treatment. Artificial pollination should be conducted between 9 and 10 am. Select the male flower that blooms on the day, remove the petals, and apply the pollen on the anther to the stigma of the female genus that was opened on the day of pollination. A male flower can give two or so female flowers. If males are not enough, use 50-100 mg/L of 2.4-D to add 20 mg/L of GA to smear torus and stigma.
