| Abstract: | To establish high-yield direct-seeding cultivating technique of a rape cultivar Zhongshuang 9, a quadratic rotational regression design was used to study the effects of cultivating techniques on biological performance before winter and seed yield. A suitable cultivating technique for high yield (more than 3 000kg/hm~2) rapeseed production was developed. The correlation between plant biological indexes before winter and seed yield was discussed. |
