【摘要】 研究结果表明，高产田冬小麦结实小穗数、每穗小花数、穗粒数、单株成穗数、单株产量等与基本苗呈负相关。通过数学模拟建立了高产田小麦穗长、结实小穗数、每穗小花数、穗粒数、单株成穗数、单株产量等与基本苗的模拟方程。作者还对经济系数与基本苗的关系，冬小麦个体经济性状的评价以及最适基本苗的确定方法等进行了研究。更多还原

【Abstract】 Research results indicate that the correlation between the economic characters ofindividual plants like number of spikelets,number of florets per spike,number of kernelsper spike,population number per plant,yield per plant,etc,and the basic Seedlings is nega-tive.By means of mathematical models,model equations are established between the eco-nomic charesters like the length of spike,number of spikelets,number of florets per spike,number of kernels per spike,population number per plant,yield per plant,ect.and the basicSeedlings.The relationship between the economic coefficient and the basic seedlings,the e-valauation of the individual plant’s economic chtlracters of winter wheat and the method todetermine the fittest basic seedling,etc.are also studied in this paper.更多还原
