严重冬春干旱年型不同水分运筹方式对冬小麦产量的效应
Efficient of Irrigation Application Regime on Yield of Winter Wheat in a Typical Dry Year
摘要
Abstract
With the method of randomized block design , four wheat cultivars with 12 irrigation methods were used to study irrigation application regime in drought year of 2010-2011 .Results indicate the yield of wheat with more irrigations raised 1 200-4 200 kg/ha comparing to dry farming ,a significantly higher grain production in tille-ring and overwatering irrigation was achieved than that irrigated in spring and with more yield in tillering irrigation , while more than 3%yield of wheat was obtained with rose water but delayed water .Irrigation in tiller+jointing+anthesis+grain filling stage and overwintering +jointing+anthesis+grain filling stage during the whole growth pe-riod have the first and the second yield ,respectively .Three times irrigations in tiller/overwinter+jointing+anthesis stage can have closed to or exceed yield than that of four times watering in spring .However , unification of higher yield and higher water use efficiency was achieved with 3 times water .There was a significant difference of the re-sponses to irrigation treatment among cultivars ,a stable yield with higher yield was gained with H 4399 in dry farm-ing,JM22 and J585 had a remarkable increased yield with added water ,which show a good productivity .关键词
