在一定条件下,油菜的合理群体结构,即构成产量诸因素主要受种植密度的影响。作者于1986—1987年在本所试验农场进行试验,供试品种为821(B.napus)。本研究在运用显著性检验和通径分析的基础上,借助电子计算机,采用数学方法,对密度与产量和产量构成因素建立其相应的数学模型,并进行定性、定量分析,为油菜合理密植提供一定依据。
Under certain conditions, the rational population structure of rapeseed, that is, the factors that make up the yield, is mainly affected by the planting density. The author in 1986-1987 on our test farm to test the test varieties is 821 (B.napus). Based on the test of significance and the path analysis, this study established mathematical models of density, yield and yield components by means of computer and mathematical method, and conducted qualitative and quantitative analysis to provide rational and close planting of rape Some basis.
