在油菜(B.napus)产量构成因素中,单位面积上角果数对单位面积产量影响最大,但每果粒数和粒重也有一定影响。本文是对增加单位面积上角果数,以及增加每果粒数和粒重等问题的初步分析,并在文中提出了相应的栽培技术措施。 Among the components of B. napus production, the number of fruit per unit area had the greatest effect on the yield per unit area, but the number of per fruit and the grain weight also had some effects. This article is a preliminary analysis of the problem of increasing the number of pods per unit area and increasing the number of pods and grain weight per unit area, and put forward corresponding cultivation techniques and measures in the paper.
