1980—1981年度,笔者曾在浙江省农业科学院试验场进行甘蓝型油菜生育特性的观察。试验田土壤为小粉土,肥力中等,前作水稻。供试品种计有特早熟的315油菜、早熟的浙油7号,中熟的九二油菜和480油菜、迟熟的三高油菜和武_2×九二选系等6个品种(系),分早(9月27日)、中(10月7日)、晚(10月17日)三期直播;顺序排列,不设重复,小区面积1厘,行距1尺,株距0.5尺。油菜定苗后每小区各选定5株,定期测定主茎叶片生长情况,按时取样考察单株叶面积、单株干重及其他性状,记载各品种的生育期和抗逆性。最后进行
In 1980-1981, the author observed the growth characteristics of Brassica napus in the test field of Zhejiang Academy of Agricultural Sciences. The soil in the experimental field is small silt, medium fertility, before rice. There were 6 cultivars (lines), including 315 pre-ripening rape, precocious Zhejiang oil 7, medium mature 92 rape and 480 rape, late ripening San Rape and Wu2 × 92 election, , As early as (September 27), mid (October 7), late (October 17) three broadcast; order, without duplication, the plot area of 1 centimeter, 1 foot spacing, spacing 0.5 feet. Rapeseed Dingmiao each district after the selection of 5, regular measurement of the growth of the main stem leaves, leaf samples were taken to observe the plant area, dry weight per plant and other traits, record the varieties of the growth period and stress resistance.
