采用裂区试验设计,以人工创造的播前不同底墒为主处理,不同施肥量为副处理,研究了陇东旱塬地区底墒和施肥对旱地冬小麦产量、水分利用效率、主要农艺性状和关键生育期光合作用的影响.结果表明,随着播前底墒的增加,旱地冬小麦的产量、水分利用效率显著增加,主要农艺性状和光合作用同步增进,其中产量、WUE、千粒重、容重在中等施肥量时达到最大值,高施肥量时有所下降,但仍高于不施肥处理.
採用裂區試驗設計,以人工創造的播前不同底墑為主處理,不同施肥量為副處理,研究瞭隴東旱塬地區底墑和施肥對旱地鼕小麥產量、水分利用效率、主要農藝性狀和關鍵生育期光閤作用的影響.結果錶明,隨著播前底墑的增加,旱地鼕小麥的產量、水分利用效率顯著增加,主要農藝性狀和光閤作用同步增進,其中產量、WUE、韆粒重、容重在中等施肥量時達到最大值,高施肥量時有所下降,但仍高于不施肥處理.

A split plot experiment was conducted to study the effect of SW and fertilization on dryland winter wheat yield, water use efficiency (WUE), main agronomic characters and photosynthesis in key growth stage was studied with which taking different manufactured soil water at planting stage (SW) as main treatment, different fertilization level as assistant treatment In east Gansu rainfed highland. The results showed that the agricultural traits and Photosynthetic increased simultaneously with the increasing of SW,the yield and WUE increased significantly which the yield, WUE, 1000 seed weight and volume weight acquired maximum when fertilization quantity was moderate. It was decreased when fertilization quantity was the highest, but still higher than Low fertilization quantity.
