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”等关键栽培技术
Through the multi-point experiment and demonstration of a new five-year double-low rapeseed new oil variety Suyou 1, the characteristics of the yield components, the population distribution of corydalis, the population structure and the seedling dynamics of 3 750 kg / hm2 were clarified. According to the reproductive characteristics of Suyou 1, we put forward the early sowing date and cultivate the strong seedlings, properly planted and control the basic groups, rationalize the regulation and enhance the resilience, and scientific fertilization to ensure high yield. Based on the “three defenses”, control “Three pests” and other key cultivation techniques
