不同冬小麦品种产量性状及水分生产率比较研究

在新疆绿洲灌溉农业区,实现农作物节水高产,筛选节水农作物品种是非常重要的.选择11个小麦品种(系),在全生育期灌三水的条件下,对其产量性状、水分生产率进行研究,结果表明:不同小麦品种生物量、产置及产量构成、水分生产率有差异.产量在6 467.69～8 755.68 ks/hm2,水分生产率在1.16～1.58 kg/m2,超过对照品种有5个,其中:9907、烟农19和93-9等品种(系)的综合性状表现好,产量较对照品种增产18.4;、17.7;和12.5;,达到了5;显著水平,水分利用率比对照品种提高19.7;、18.2;和12.9;.

Comparative Study on Yield Traits of Different Varieties of Winter Wheat and of Water Productivity

It is specially considered in water- saving high yield of agricultural crops,selecting and screening water- saving crops varieties on agricultural region in oasis of Xinjiang.The yield traits,water production of 11 selected wheat varieties were analyzed under irrigation Sanshui in the whole growth period.The results demonstrated that there were difference between the biolass,yield,production structure and water production of different wheat varieties.The yield was 6 467.69-8 755.68 kg/hm~2,the water productivicty was between 1.16 - 1.58 kg/ m~3.There were five varieties whose yield and water productivity were more than that of CK.Among them,the overall performance of 9 907,tobacco growers 19 and 93-9 varieties(lines) were excellent.Their yield was increased by 18.4%,17.7%and 12.5%compared with CK,which reached 5%significant lwvel.The water use efficiency was increased by 19.7%,18.2%and 12.9%compared with the control variety.
