摘要
在应用有机基质育秧的前提下,比较了旱育秧、半旱育秧、水育秧、湿润育秧4种方式对机插秧苗素质的影响。结果表明:旱育秧和半旱育秧秧苗的不定根数、平均不定根长、最长根长、根鲜质重和干质重等根系指标要好于水育秧和湿润育秧,且白根率高,根系吸收面积和活力也好于水育秧和湿润育秧,其叶面积较大,叶绿素含量高,苗高15～20cm,茎基部较宽,根系盘结力强,比水育秧和湿润育秧更符合机插秧苗的要求。
Under the prerequisite that grown seedlings with organic matrix , choose Si Dao No.1 and Wu Yu Jing No.3, have compared dry-raised seedling , half dry-raised seedling , water raise rice seedings , moist raise rice seedings 4 kinds of way for machine transplant rice seedlings the influence of sprout quality. The results showed that dry-raised seedling and half dry-raised seedling the indefinite thoroughly several, in average indefinite thoroughly long, longest thoroughly long, thoroughly fresh weight of rice shoot with the root departments such as dry weight index were on good terms in water-raised seedling with moist-raised seedling , and in vain root rate was absorption area high thoroughly with vigour was also better than water raise rice seedings with moist raise rice seedings , theirs product of face of blade were greater , chlorophyl content were high , seedling height 15-20 cm, theirs strong that stem base department coil than wide, root department to close, than water-raised seedling with moist-raised seedling was more suitable machine transplant rice seedlings the requirement of sprout.
