不同灌水处理对强筋小麦新麦19产量及品质的影响
Effects of irrigation on yield and quality of high-gluten wheat Xinmai 19
摘要
Abstract
A field trial was conducted during 2009-2010 at the experimental station of Xinxiang Academy of Agri-cultural Sciences and Gaocun Village in Huixian City ,Henan Province to verify the effects of irrigation on yield ,dry mat-ter accumulation amount (DMAA) ,dry matter distribution ratio (DMDR) ,water use efficiency (WUE) ,and quality of high-gluten wheat .The trial was implemented by using randomized block design with three replications .Five treatments of irrigation were included :pre-sowing water + jointing water + flowering water (T1 ) ,pre-sowing water + jointing water (T2 ) ,pre-sowing water + winter water + booting water (T3 ) ,winter water + booting water (T4 ) ,and winter water + pre-jointing water+ flowering water + filling water (CK ) .The results showed that the irrigation treatments af-fected significantly grain yield ,DMAA ,DMDR ,WUE and quality characters of Xinmai 19 at both sites .The yield of T1 was the highest ,which increased by 5% in average at the two sites compared with CK .The DMAA ,DMDR ,WUE ,ir-rigation WUE and precipitation WUE of T1 were wholly higher than those of CK .The WUE of T2 was the highest ,which increased by more than 6% compared with CK .When irrigated twice or more during the whole growth period ,the grain quality tended to be worse with the increase of irrigation frequency .There was little difference of grain quality between ir-rigation once and no irrigation after anthesis ,both of whose grain quality was prior to that of irrigation twice after anthe-sis .In comprehensive view of yield ,quality and WUE ,T1 was the best irrigation mode for high-gluten wheat production in northern Henan Province .关键词
