摘 要:通过对春小麦生物性状指标、与水肥之间关系、指标间的关系、决定生长状况的主成份进行分析,得出水肥对春麦陇春8139增产的宏观机制;陇春8139春小麦各生物性状之间发育协调;反映其生产状况的主要因子变量为产量、耗水、穗粒数、千粒重。在生产中进行品比、估产、测产可通过Fi的考察得到。即F1决定的群体生长状况,穗粒数反映成穗状况的F2,千粒重反映灌浆情况的F3。This paper dealed with relationship between the spring wheat's biology characters, and these characters' tie with water and fertilizer, also the main factors which decided statue of spring wheat. Through analysis, we could understand why and how water and fertilizer affecting the yield, biology yield. We got that there were coordination tie among these characters, also got several main factors that could decide the growth statue of spring wheat. These are fallowing: yield, water consume, eargrains, weight of thousand grains. In practice, we can inspect Fi to get the data of yield, and moral characters of spring wheats. F is about the overall status. F2 is about completing ears that decided by ear grains. F3 reflects on filling extent decided by grain weight.
