不同生育阶段灌水处理对谷子生长发育的调控效应
Effects of irrigation on growth and development of foxtail millet at different growth stages
摘要
Abstract
In Dunhuang city where annual rainfall is about 39mm ,effects of irrigation at different growth stages on main morphological characteristics and yield of foxtail millet were studied .Additionally ,gray correlative degree analyses were employed to study the correlations between main morphological characteristics and yield .The result showed that treatment with irrigation three times at jointing ,heading and filling stages shortened the growth period by 5 .4 days ,in-creased plant height ,length of panicle ,panicle weight per plant ,seed weight per plant ,straw weight per plant ,and yield per 667m2 by 51 .1 cm ,1 .2 cm ,14 .2 ,12 .3 ,3 .1 g ,225 .85 kg than no irrigation ,respectively .Yield by no ir-rigation treatment during the growth period was only 105 .78 kg·666 .7m - 2 .However ,treatments with irrigation three times at jointing ,heading and filling stages ,irrigation two times at heading and filling stages and only irrigation once at heading stage caused high yields of 339 .91 ,331 .6 kg·666 .7m - 2 and 288 .31 kg·666 .7m - 2 ,respectively .The results demonstrated that irrigation at the heading stage of foxtail millet is most effective .There were close correlations between seed weight per plant ,panicle weight per plant ,length of panicle and yield by gray correlative degree analysis .关键词
