1. Topdressing and watering. After planting and living, combined with watering, chasing the decomposed farmyard manure, promoting the roots to tie down and cultivate strong seedlings. A second top dressing is carried out when the plant grows to a height of 30 cm. Later, with the increase of temperature, the growth of the plant was accelerated. When the first batch of female flowers was opened, the human excrement was applied once. After the first batch of fruit is harvested, 20 kg of compound fertilizer is applied per acre, and then fertilized once every 7-10 days. Foliar spray can be applied to the leaves before flowering. In the growth process of bitter gourd, a large amount of water is needed. In the case of no fruit, it should be poured once every 5-7 days.
2. Cultivate weeding. Combine weeding at the seedling stage and shallow cultivating twice. Cultivate 2-3 times during the subsequent growth period. If there are weeds, you can remove them by hand.
3. Rack the whole vine. When the vine grows to a height of 50-70 cm, each side of the plant is inserted into a bamboo stalk of about 2 meters in length, and each of them is placed on an adult-shaped frame, and the bitter melon is fixed on the bamboo raft to prevent the vines from intertwining each other. When bitter gourd begins to pump vines, it should be combined with the characteristics of the variety, and the side vines should be removed or selected. The main vines should be removed from the side vines, and the side vines should be removed below 1 meter. In the middle and late stages of plant growth and development, the plants should be removed. The old yellow leaves in the lower part are used for ventilation and light transmission.
4. Disease prevention and treatment. The diseases of bitter gourd mainly include blight, powdery mildew and downy mildew. In the early stage of wilt disease, new high-fat membrane can be sprayed with 70% thiophanate-methyl wettable powder; when powdery mildew or downy mildew occurs, it can be sprayed with new high-fat membrane and 15% powder rusting 200-300 times.
