摘要
为摸索防倒伏新产品"劲丰"在水稻上的应用效果,进行田间试验。试验表明:在水稻破口期应用"劲丰",降低植株高度2.8cm,穗茎节、倒2节分别比对照缩短2.2cm、0.6cm,有明显的防止倒伏的效果;水稻的结实率和千粒重也有所增加,水稻增产14.37%。
In order to explore the applying effect of new lodge-resistance variety ＂Jinfeng＂ in rice, a field experiemt was c0onducted. The results showed that in rice ear sprouting period, the application of ＂Jinfeng＂ could reduce plant height by 2.8 cm; ear stem node and converse second node were shorter by 2.2 cm and 0.6 cm comparing with control group so that the variety has obvious lodge-resistance effect. The rice seed rate and thousand-grain weight were also increasing and the yield was increased by 14.37 %.
