油菜产量与结角层时空结构关系的研究

通过对江苏省20多个油菜试验、示范点十多年时间积累的1100多套系统资料的分析整理，研究了油菜群体状态下产量与结角层四维时空结构的关系。明确了结角层厚度与结角层密度是油菜重要的群体质量形态指标，也是综合性经济指标。结角层厚度主要受第一有效分枝着生位置和主轴、一次分枝的长度两个因素影响，结角层密度主要受群体中主轴及一、二次分枝的数量和分枝上角果着生密度三个因素影响。提出了高产群体质量结角层厚度与结角层密度的量化指标，提出了油菜优化群体质量超高产栽培的基本原理：充分利用冬前的太阳能，适当增加物质投入；关键措施：适期早播早栽，适当降低密度，适量增加肥料。

Research on Relation of Rape Seed Output and Angle Fruit Floor Space-time Structure

Through testing more than 20 pieces of rape in Jiangsu Province, demonstration pilot project, the analysis of more than 1100 sets of systematic materials accumulated in time is put in order in more than ten years, have studied the output and relation of structure between one layer of four-dimensional space-time of angle fruit under colony's state of the rape. Define horn fruit layers of thickness and horn fruit layers of density rape important colony quality index; it is the comprehensive economic indicator too. Horn fruit layers of thickness catch position, main shaft and one length two influence of factor of branch first effective branch mainly, horn fruit layers of density receive colony main shaft and one - two branch count, branch grow neat degree and branch upper horn fruit born density 3 pieces of influence mainly. Propose fertile colony corner fruit layers of thickness and horn fruit layers of quality index of density; Have proposed the basic principle of the optimization colony's quality of ultra fertile culture: The solar energy before fully utilizing winter, increase material input properly; Key measure: Right one sows imposing early, reduce the density properly, increase the fertilizer in right amount.
