In the winter off-season, the use of mulching, plastic sheds, artificial pollination, and other means of cultivation are the main reasons. In March of the following year, they can be marketed. The following points should be made in cultivation:
1. Select soil and soil preparation: choose to shelter from the sun to facilitate irrigation, soil fertility loose, sandy soil with high organic matter content.
2. Variety selection: Select white hull and long conical cultivars with prominent surface nodularity, thick stalks, and low branching nodes, with higher yield and better quality.
3. Seed germination: Momordica charantia seeds are tanned for 3~4 hours before germination, then soaked in warm water at 50°C for 10 minutes and added with a new high-fat film dressing (mixed with seed coating agent) to repel insects in the ground and isolate virus infection. Does not affect the germination and swelling function, strengthen the respiratory intensity, and increase the seed germination rate.
4. Pre-emergence management: High temperature and humidity must be maintained before emergence. Spray 600-800 times of new high-fat membrane to spray the soil surface. This can protect water from evaporation, sun protection, drought, insulation and frost protection, and prevent soil compaction. And isolation of pests and diseases, improve the emergence rate.
5. Fertilizer and water management: Generally, 2500 kg of bitter gourd is produced per mu, and the amount of pure nitrogen is 18 kg per mu. The ratio of nitrogen, phosphorus and potassium is 1.0:1.3:2.1. The basal fertilizer was applied at the time of sorghum, accounting for 60%, topdressing for 40%, and applied two to three times after squashing. And spraying strong guillotine to thicken the guati, to strengthen the directional delivery of nutrients, promote the rapid development of melons, melons, beautiful, juicy and tasty; growth cycle does not fall, not melon, no crack melon, no malformation melon.
6. Pest control: Diseases of balsam pear planted off-season are more serious than those planted in the normal season. Insect pests mainly prevent aphids and powdery mildew. We can use the imidacloprid 600-800 times or Sinko 800-1000 times liquid + new high fat film for prevention and treatment. In general, after spraying, bitter gourd is sprayed. Afterwards, it can be sprayed once a month according to the seedling situation. According to past planting experience, a total of 2-3 sprays can be applied.
