摘要
利用中国科学院最新研制的稀土农用光作为补光光源,研究其不同波长和不同补光时间对番茄幼苗生长及开花的影响。结果表明:相比于对照组和普通LED补光处理,450 nm、650 nm和450 nm+650 nm组合3种稀土农用光源均提高了壮苗指数,补充450 nm+650 nm波长组合光6 h更利于形成优质壮苗,3种光源的壮苗指数均随补光时间的延长而提高;补光在一定程度上使番茄的始花节位升高,同时番茄的始花期也相应延迟。
Using rare earth agricultural light,invented by Chinese Academy of Sciences recently,as experimental light,the effects of the different wave length lights and different light time had been investigated on the tomato growth and flowering.The results showed that,compared with the control group and the ordinary LED light treatment,seedling index of the treatments with 450 nm、650 nm and 450 nm ＋650 nm rare earth agricultural lights were increased,adding blue and red light 6 h were more conducive to the formation of high quality seedling and the seedling index was increased with the increasing light time;the initial floral node with filling light was raised,meanwhile,the initial flowering time of tomato was also delayed.
