摘要
通过连续 5年双低油菜新品种苏油 1号的多点试验示范 ,明确了 3 750 kg/hm2以上的产量构成、角果群分布、群体结构、苗情动态等特征。根据苏油 1号的生育特性 ,提出了适期早播 ,培育壮苗 ;适当早栽 ,控制基础群体 ;合理化调 ,增强抗逆能力 ;科学施肥 ,确保高产需要 ;立足“三防”,控制“三害”
Experiment and demonstration of Suyou No.1 were condueted for five years. The results showed characters of yield factors, pod population distribution, population component and seedling of growth process of which exceeding 3750kg/hm 2. According to the development characteristic of Suyou No.1, the cultural technics were pointed as follows: Early seeding at appropriate period to cultivate strong seedling; praperly transplanting to control basic population; reasonable application of chemical controlling to inhance ability of unti negative factors; appropriate application of fertilizer ensure achievement of high yield productivity.
