摘 要: | [目的]为了探讨小麦孕穗期不同追肥方式对籽粒产量和产量性状的影响。[方法]以西农9871为材料,于2009~2010年度陕西三原县在小麦孕穗期进行了5种追肥方式在小麦上的试验。[结果]土壤追施尿素的产量最高为9.4 t/hm2,比不追肥(CK)增产36.2%,叶面喷施旺得丰和叶面喷施磷酸二氢钾分别比CK增产18.8%和11.6%。[结论]在小麦孕穗期土壤追施尿素、叶面喷施旺得丰和叶面喷施磷酸二氢钾均可明显增加每穗粒数、小穗数和千粒重,进而提高籽粒产量,而叶面喷施尿素并不能明显提高产量。

Abstract: | [Objective]The research aimed to study the effects of fertilizer application in wheat booting stage on characteristics of grain yield.[Method] Xinong9871 was taken as material.The field trail of five different ways in wheat booting stage in Sanyuan County,Shaanxi Province in 2009-2010 was conducted.[Result]The yield of topdressing urea was the highest of 9.4 t/hm2,which was increased by 36.2% compared with no top application(CK).Compared with CK,the yields of foliar spraying Wangdefeng and foliar spraying potassium dihydrogen phosphate increased by 18.8% and 11.6%,respectively.[Conclusion] In wheat booting stage soil topdressing urea,foliar spraying Wangdefeng and foliar spraying potassium dihydrogen phosphate could significantly increase grain number per panicle,spikelet number per spike and 1000-grain weight,so further improve grain yield.And foliar spraying urea didn't significantly increase grain yield. |
