Cabbage planting has been dominated by traditional spring cabbage and autumn cabbage for many years. Due to the centralized listing, the price of vegetables is low and the income of growers is not good. From July to September each year, the market is lacking in cabbage and the price is high. At present, it is suitable for summer cultivation. There are not many varieties of cabbage that can be listed in July-September, but it is very heat-resistant and moisture-resistant, resistant to soft rot, strong in sclerotinia, and has good early maturity and good quality. It is an anti-season production of cabbage. The ideal variety. In recent years, the area of ​​open vegetables in Qinghai Province has increased year by year, but the variety of vegetables is small, the market information is insufficiently connected, and the benefits are unstable. For example, the cultivation of Zhonggan 11 and 8398 cabbage varieties has a long growth period, and the climate factors have great influence. Cracking causes a decrease in commerciality. Planting Xingtai's Shun's Cabbage Variety and 8132 Cabbage Variety, which can be marketed more than 50 days after planting, provide summer and autumn vegetable off-season with good benefits. It has become an effective way to increase the income of vegetable growers in flood towns in Ledu District, Haidong City. Especially the quality is excellent, can be raw, sweet taste, and the market price is higher.
