The golden bell bitter gourd has been welcomed by the Hong Kong market because of its characteristics of wide shoulder, thick flesh, crisp texture, sweet taste, green skin, and storage and transportation. Therefore, the economic benefits of planting golden bell bitter gourd are high, and the general mu gain can reach 4000-5000 yuan and the highest can reach 10,000 yuan. High-efficiency cultivation experience is as follows: First, grasp the best sowing time Bitter gourd is warm and cold, but the bell bitter gourd is more cold-resistant than other bitter gourds, and the heat-resistance is poor. In different places, only the best sowing time can be obtained to obtain higher quality. The output, better prices. The best sowing date for Zhanjiang and Maoming is from December to January of the following year, the harvesting period is from March to April; the best sowing time in Yangjiang, Kaiping, Gaoming and Guangzhou is from January to February, and the harvesting period is from April to May. The best sowing time in Qingyuan and Shaoguan is from May to July and the harvest is from August to September. Second, master the best cultivation density around the environment, climate, different cultivation practices, the best cultivation density is not the same. In the Maoming area in early spring, the golden bell bitter gourd was planted. Since the temperature was still relatively low at that time, the melon seedlings grew slowly. Only increasing the planting density and trying to leave the main vine seeds in order to obtain higher yield and better quality, the optimum planting density was 2000-2200 per acre, about 500 grams per mu. Even in winter planting in Hainan Province, the temperature is relatively high. Melon vines grow fast. The optimum planting density is about 1500 plants/mu. The main vine and a side vine can be maintained. The amount of mu for use is about 350 grams. Planting seasons in Guangzhou, North Guangdong and other places have higher temperatures and melon vines grow faster. The optimum planting density is 1000-1200 strains, and the amount of used acres is about 250-300 grams. When the temperature is higher, the planting density is thinner, which not only saves the cost of seed, but also helps melon seedlings grow and reduce pests and diseases. Third, take appropriate protective measures during low temperature 1, mulching film coverage. In Zhanjiang, Maoming, Guangzhou, and other places in order to catch up with the early market, get a good price, often early to plant golden bell bitter gourd. In order to avoid freezing or freezing of the seedlings, it is best to use a nutrition cup seedling and cover it with a plastic film, so that the seedlings have a certain ability to resist cold. When the temperature begins to rise, they are moved to the field for planting. 2, the use of gibberellin to stimulate male flowers open. The golden bell bitter gourd is a strong female bitter gourd. The main vines rarely open male flowers. When the temperature is low, there are not many male flowers in the side. Therefore, in the low temperature season, male flowers were found to be very rare, affecting normal pollination, can be sprayed once with gibberellin at 50ppm (0.5g/kg water) at the early flowering stage, and can effectively promote the opening of male flowers. 3, skillfully picking side vines. When the bitter gourd planting density is high, all side vines should be removed in order to facilitate ventilation and light transmission and reduce diseases. However, if all the side vines are removed, the amount of male flowers is insufficient and it is difficult to pollinate. In severe cases, the output will be greatly affected. influences. Therefore, it is not necessary to remove the lateral vines or the lateral vines from the base after 7 days of isolation. The amount of male flowers is insufficient and it is difficult to pollinate. In severe cases, the yield will be greatly affected. Therefore, you can use a 7-day transpiration of the lateral vine or picking side vines when not plucked from the base, retain about 20 cm 2-3 sections side vines, to ensure that there is enough male to pollination. In addition, strengthening the management of fertilizers and water, strengthening prevention and treatment of disease, timely harvesting, and careful packaging and transportation are all necessary to improve the yield and quality of the golden bell bitter gourd.
