摘要
通过对比分析不施肥与配合施肥条件下小麦的产量与产量结构,结果表明:配合施肥可以极显著提高小麦单位面积穗数、穗粒数和千粒重,三者共同作用致使小麦产量极显著提高。配合施肥条件下,生物量极显著提高,而对收获指数影响不显著。不同品种具有不同的收获指数,且收获指数与株高呈极显著负相关。
Comparing the yield with yield structure of winter wheat under fertilization or no, it showed that spikes per hectare, grains per spike and kilo -grain weight increased extremely remarkably under fertilization, which affected together and made for the yield increasing. Under fertilization, the biomass increased extremely remarkably, however harvest index was affected unremarkably. The different varieties had different harvest index, and the harvest index had extremely remarkably contrary correlation with plant height.
