“稻杰”对水稻生长发育的影响

Effect of 'Daojie' on Growth and Development of Paddy Rice

为避免药剂用量高、长残留对环境污染严重等问题,进行试验测定新型除草剂"稻杰"的安全性。以98-131品种为试材,设置高、中、低3种不同浓度的"稻杰"和不施除草剂(CK)4个处理,研究"稻杰"对水稻杂草鲜重防效、水稻干物质积累、分蘖、产量等性状在不同浓度下的变化规律。结果表明:三种不同浓度"稻杰"之间对水稻影响无明显差异,与对照之间差异极显著,都远高于对照。说明低用量"稻杰"对水稻有很好的效果,而且可以保护环境,减少残留。

The experiment of detecting the .safety of new herbicide ＇Daojie＇ was conducted to avoid environment pollution. Taking 98-131 as experimental material,the law of effect of ＇Daojie＇ on the growth and development of paddy rice was studied under four treatments. After comparing the change of weed fresh weight,dry matter of the paddy rice,tillers and yield under the treatments,the results showed that there was no obvious differences among the treatments which applying ＇Daojie＇ ,the indexes were all higher than the CK,and there was significant different between them. Therefore,the lower concentration was best for good effect and less pollution to the environment.
