1. Fertilizer treatment: Immediately after planting, the planting water should be poured immediately. After the planting, the seedling water should be poured in one week. After that, the seedlings should be sown. After 10 days, you will be able to grow the seedlings with water and fertilizer, and then water once every 6-7 days. In the flowering period, it is necessary to properly seedling the seedlings, and to cultivate and keep the sorghum. After the first melon is seated, watering and promoting it. During the fruiting period, it is advisable to pour water once every 5-7 days. Bitter gourd seedlings are not resistant to fertilizer, and topdressing should be thin. After the start of the melon, the fertilizer should be continuously fed, and the water should be combined and watered once every 10-15 days. Each time, 10 kg of urea or 15-20 kg of compound fertilizer should be used. At the peak of the results, 2-3 times of superphosphate should be added, 10-20 kg each time to prevent premature aging and delay the harvesting period. If the topdressing is insufficient during the fruiting period, the plant grows weakly, the side branches are thin, the leaves are yellowish, the melons are few, the melons are small, the yield is low, the quality is worse, and the bitterness is thickened.
2, the frame pruning: bitter melon stalks, it is necessary to frame the vines in real time, so as not to be damaged by the wind, because the female flowers of the bitter gourd side vines are produced later, the base side vines should be removed to show the superiority of the main vine results. Otherwise, the side vine grows prosperously, which not only squanders the nutrients of the plant, but also leads to madness, causing signs such as melon and premature aging. Generally, when the main vine grows to 50-70 cm, the whole vine is started, and all the side vines are removed from the base, leaving only the main vines on the shelf. After the main vine is put on the shelf, if there is no female flower on the side vine, the side vine will be removed from the base. If there is a female flower, the melon should be picked up in real time. In the late growth stage, in order to transmit light through the wind, the old leaves, diseased leaves, yellow leaves and tiny side branches should be removed in real time.
