Key Technologies for High-yield Cultivation of Chinese Cabbage in Open Field in Autumn
In order to promote high-quality and efficient production of Chinese cabbage in open field in autumn,based on the production situation of 67 production entities in the'2023 Autumn Open Field Chinese Cabbage High Yield Challenge'activity in Beijing,the experiences for high yield were summarized and analyzed.The selection of high-yield and stable variety is a prerequisite for high yield.Timely sowing,raising seedling and transplantation are basics for high yield.Planting density,yield rate and individual plant weight are the three elements of yield composition.Management of water and fertilizer is the guarantee for achieving high yield,and the application of light-simplified technologies is the key for efficient production.At the same time,the following key technological points are discussed and proposed in order to provide reference for the production of Chinese cabbage in open fields in autumn,'Beijingxin No.3''Jinhuangmei''217 1''Wudongcai'and'Lüyou No.3'can be selected for winter storage.The suitable sowing date for direct sowing production method is from August 5th to 12th and the appropriate time for transplanting mothod of seedlings is in late August.Large plant varieties are suitable for planting 3 000-3 500 plants per 667 m2,while small plant varieties are suitable for planting around 7 000 plants per 667 m2.
