Songjiang County, Jing Village, Zhang Jing Jing Bazi Bridge production team in 1990 to test the Shanghai Academy of Agricultural Crops selected low-erucic acid rapeseed new varieties to obtain high yield Youyou Qing. The team of 25 contractors planted 43.39 mu, average mu 151.59kg, an increase of 39.51% over 1989, compared with the same Shuangluo production team planting the same crop of oil Huizhou 50 average yield 19.85%, mu yield first in the township. First, timely early sowing, nurturing strong seedlings leave enough seedling, timely early sowing, improve the quality of sowing and management is to cultivate strong seedling foundation. In view of the characteristics of Shenyou genus Brassica napus, it was planted on September 20, 1989. The ratio of seedling to field was 1: 5.5, and the seeding rate per acre was 0.5 ~ 0.75kg. Ammonium and superphosphate each 31kg; after emergence and time seedlings and topdressing Miao.
