移栽油菜产量是由单位面积内有效油菜株数、每株有效角果数、每角粒数和千粒重构成的,历年油菜丰产方、高产田的生产实践结果表明,油菜高产群体不仅要有足够的个体数量为基础,同时要提高群体内各个体的质量。高产油菜群体质量的核心是角果群质量(角果的数量和质量)。如何调整主轴与分枝的构成,使角果群组成结构更趋合理并保持后期良好的受光姿态;如何协调源库关系,使前中期积累的营养生长优势转化为生殖生长优势,提高油菜花
Transplanting rapeseed yield per unit area is the number of effective rapeseed, the number of effective pods per plant, per horn and grain weight per 1000 formed, past rapeseed yield, high yield field production practice results show that rapeseed yield group not only have enough The number of individuals, based on the same time, to improve the quality of the individual groups. At the core of high-yielding canola populations is the population of the caper population (quantity and quality of the pods). How to adjust the composition of the main axis and the branches to make the structure of the horn group more reasonable and maintain a good light-receiving attitude in the late stage; how to coordinate the relation between source and sink so that the advantages of vegetative growth accumulated in the middle and middle stages can be transformed into the advantages of reproductive growth and rape
