摘要
本文通过分析认为.小麦产量构成因素之间不存在相互制约关系.只存在穗数、穗粒数、粒重的单向制约.这种制约关系原则上也适用于其他作物.此外·根据对穗数、穗粒数和粒重受制因素的综合分析.提出了协调产量构成因素结构的途径与措施.
According to the analysis in the paper,there is no interactive relationship between yield combinational factors of winter wheat. There is only one -way interact among ear numbers, grain numbers and grain weight. This kind of interactive relationship fits for other crops in principle. Moreover.based on muti-analysis of restricted factor to ear numbers,grain numbers and grain weight,the way and measures for coodinating composition of yield combinational factors were presented.
