【摘要】 以冬小麦陕农981为材料,采用单因素随机区组设计,研究了不同时期喷施叶面肥绿色奇素对陕农 981灌浆期旗叶光合特性、籽粒灌浆特性和产量的影响。结果表明：绿色奇素能够提高小麦灌浆期旗叶的光合速率和籽粒平均灌浆速率,分别较对照提高14．58%～25．68%和0．09%～4．27%；增加籽粒干物质的积累量,较对照增加0．99%～4．56%；对株高和产量有不同程度的影响：不同时期喷施对株高的影响大小依次为开花期＞拔节期＞灌浆期＞分蘖期＞返青期；对产量的影响大小依次是拔节期＞灌浆期＞开花期＞分蘖期＞返青期,分别比对照提高13．2%、11．57％、8．8％、8．1％和2．2％。更多还原

【Abstract】 Based on randomized block design for single factor,the effect of Jin Nuofeng on the flag leaves physiological characters,grain grouting characters and yield of the winter wheat Shaannong 981 was studied. The result showed that spraying Lvse Qisu on winter wheat in different stage increased the flag leaves photosyn- thesis rate and grain grouting rate by 14.58%～25.68%,0.09%～4.27%,respectively,and enhance grain dry matter accumulation in grain by 0.99%～4.56% compared with CK;the effects of wheat height and yield on spraying in different stage were different.The best spraying period was in jointing stage,the next was in the milk stage,which rise by 13.2% and 11.57% more than that of CK,respectively.更多还原
