摘　　要：为研究减施化肥、增施有机肥对渭北旱地小麦生长及品质的作用效果,以国审旱地小麦新品种渭麦9号为研究对象,以尿素、缓控释氮肥、有机肥不同种类氮肥单施或配施设置6种不同处理,以不施肥为对照,比较不同处理对渭麦9号生长的影响。结果表明,缓控释氮肥减量70%即97.2kg/hm^(2)、有机肥减量30%即420kg/hm^(2)对产量提高的效果最为显著,单施有机肥能够提高小麦容重。渭北旱塬土壤中有机质长期缺乏,小麦产量及品质提升较难,因而在旱地小麦施肥中加入有机肥意义重大。In order to study the effect of reducing fertilizer application and increasing organic fertilizer application on the growth and quality of wheat in Weibei dryland,a new wheat variety‘Weimai 9’was selected as the research object.Six different treatments were set up with urea,slow-release nitrogen fertilizer,and organic fertilizer with differ⁃ent types of nitrogen fertilizer applied alone or in combination.The effect of no fertilizer application on the growth of Weimai 9 was compared with that of no fertilizer application.The results showed that 70%reduction of slow-release nitrogen fertilizer(97.2kg/hm^(2))and 30%reduction of organic fertilizer(420kg/hm^(2))had the most significant effect on yield improvement.Single application of organic fertilizer could improve wheat bulk density.Due to the long-term lack of organic matter in the soil of Weibei dryland,it is difficult to improve the yield and quality of wheat.Therefore,it is of great significance to add organic fertilizer to the fertilization of wheat in dryland.
