摘要
为探索研究水稻节水、省工、高产栽培的新技术,以中作59为供试品种,研究了解膜、黑膜、白膜3种水稻种膜栽培方式与传统水稻栽培比较,对水稻产量、生育性状、光合特性、品质及土壤养分的影响。结果表明,种膜栽培的产量以黑膜和白膜较高,解膜次之,比对照可以提高产量7.7%～24.0%,缩短生育期5～7天,地上部光合积累量增加;种膜栽培对稻米品质影响不显著。水稻种膜栽培可以节水、省工,还具有减少杂草、病虫害、提高肥料利用效率的作用。
The effect of different seed-film cultivation was studied on grain yield,vegetative growth,photosynthetic characteristics and grain quality in rice using japonica rice ＂Zhongzuo59＂ as material with four treatments：a（white plastic seed-film）,b（black plastic seed-film）,c（decomposable seed-film）and d（normal cultivation）.The result indicated that seed-film cultivation could save water,save laborite could increase grain yield 7.7%-24.0%,increase photosynthetic rate and above ground dry weight,and decrease growth dates 5-7days respectively by normal cultivation.In addition,there were no significant differences in grain quality with four treatments.Seed-film cultivation could reduce the production of the grass.The stripe virus of rice in seed-film cultivation was significantly lower than normal cultivation.The seed-film cultivation also increased the ratio of the fertilizer using.
