摘要： 为了研究冬小麦在小播量条件下的产量和品质表现,20012003年在北京安排了两个年度的秋播试验。参试品种有DS1号、临抗1号、冀麦30、鲁麦21和京411,京411是对照品种,播种量是22.5kg/hm2。2001-2002年度,参试品种中临抗1号的最高产量达到6652 5kg/hm2;2002-2003年度中,京411、鲁麦21、临抗1号、DS1号、冀麦30的平均产量分别达到8537 6,7403 7,7353 75,6836 25,6169 8kg/hm2,品种的品质也较好。试验中,这些品种有正常的生育表现,较强的分蘖能力,旺盛的生理活动。在产量结构中,这些品种的单株穗数较多。

Abstract: In order to study effects of yield and quality under conditions of precision seeding of little sowing amount for the winter wheat,the autumn-sown experiments in two years were conducted during 2001 —2003 in Beijing. DS No. 1, Linkang No. 1, Jimai No. 30, Lumai No. 21 and Jing 411 belongs to experimental varieties. Jing 411 is contrast variety. Sowing amount is 22. 5 kg /ha. The best yield of Linkang No. 1 among experimen- tal varieties comes to 6 652. 5 kg/ha during 2001 —2002. The average yield of Jing 411,Lumai No. 21,Linkang No. 1,DS No. 1 and Jimai No. 30 comes to 8 537. 6,7 403. 7,7 353. 75,6 836. 25 and 6 169. 8 kg/ha respective- ly in 2002-2003. Experimental varieties have better quality too. These varieties have a normal expressions of growth and development,stronger ability of tiller, vigorous physiological actions. The number of spike per plant among yield structure more than one of general varieties.
