摘要
本试验结果表明,灌溉处理对于改善木薯的一些农艺性状具有良好的促进作用。在木薯苗期和块根形成期,各种灌溉方式对木薯的株高和茎径明显高于对照,木薯进入块根膨大后期株高和茎径逐渐停止生长,其中微灌对木薯的株高的影响比其它灌溉处理的效果显著,而对茎径的生长效果显著则是滴灌。木薯生长率在苗期和块根形成期增较快,进入块根膨大期就逐渐停止生长。
The experiment results show that the irrigation treatment for improving a number of agronomic traits of cassava plays an important role in promoting. In the cassava root formation stage, irrigation of the cassava plant height and stem diameter is significantly higher than the antitheses, and entry to root enlargement period of plant height and stem diameter gradually stop growing, in which micro-irrigation on plant height of cassava heighter than other irrigation treatment, while the growth of stem diameter marked effect is the drip irrigation. Cassava growth rate in the seedling and root formation stage increased rapidly, into the root enlargement view to gradually stop growing.
