| 摘 要： | 选用不同品质类型(强筋、中-强筋、中-弱筋和弱筋)的7个小麦品种作为供试材料,在攀西地区安宁河流域的西昌市进行了2种氮肥水平的田间试验。结果表明,不同小麦品种的生育期、分蘖动态及产量构成等均有明显差异,且受施氮水平的影响。增施氮肥(施氮量150 kgN/hm2与施氮量75 kgN/hm2相比)有增加小麦有效穗数和穗粒数、降低千粒重的趋势,但增加或降低的幅度在品种间有较大差异。不同品质类型小麦品种的产量对氮肥的敏感性不同,从总体上看,氮肥对强筋小麦品种的增产作用较大,对弱筋小麦品种的增产作用较小。

| Abstract: | Panxi region was a special ecological region and located in the bonded block of Sichuan basin and YunGui plateau and QingZhang plateau.Field experiment involving two nitrogen fertilizer levels and seven different-quality wheat varieties was accomplished in Xichang county of Paxi region in 2005～2006.The results indicated that the growing season and tillering dynamics and yield composition of different wheat varieties had obvious difference and were influenced by the nitrogen fertilizer levels.Adding nitrogen fertilizer(compared the 150 kgN/hm2 applied rates with 75 kgN/hm2) had the tendency to increasing effect ears,grains per ear and decrease thousand-grain weight,but its increase or decrease variation amplitude of varieties was large.The sensibility of yield to nitrogen fertilizer was different along with different-quality varieties.On the whole,the function of increase in yield of nitrogen fertilizer on strong bran gluten wheat was large but on weak bran gluten wheat was small. |
