种子抗旱剂对油菜生长发育与产量的影响

Effect of Seeds Resist Drought on Growth and Development and Yield in Rape

利用抗旱剂对油菜种子进行丸粒化处理,田间试验研究结果表明:不同抗旱剂处理对油菜的生长发育、农艺性状及产量形成有不同程度的影响。使用抗旱剂可在一定程度上改善油菜的经济性状和产量结构,提高油菜籽产量,尤其对改善丸粒化油菜种子的发芽率、出苗率和种子活力,增加植株高度以及降低有效分枝点高度均有显著效果,从而为种子抗旱剂的有效利用,实现油菜大面积抗旱保苗提供了一条有效途径。

Pilled rape-seed melted with seeds resist drought, the result showed that the effects of different resist drought reagent were difference on the growth and development and yield in rape. With applying seeds resist drought, the economic characters and yield can be improveed on certain extent , the emergence rate and seed vigour were raised especially ,the plant length was increased and effective branch position was reducted notably . It would offer a effective channel for the rape produce in large scale.
