不同包衣剂对直播稻苗期素质及产量的影响

Effects of Different Coating Agents on Seedling Quality and Yield of Direct Seeding Rice

通过选择市场上效果较好的包衣剂以及新推出的包衣剂,探究药剂包衣对直播稻秧苗素质及产量结构的影响。结果表明,多·咪·福美双处理可有效提高水稻出苗率、苗期根冠比及叶绿素含量,提高水稻秧苗素质,壮秧生长整齐,最终形成大穗,在同样栽培条件下,壮秧容易获得高产,即包衣剂处理可有效提高产量。

The effects of chemical coating on seedling quality and yield structure of direct-seeding rice were investigated by selecting coating agent with better effect in the market and the newly launched coating agent test.The results showed that Do-mi.Fo-mei double treatments could effectively improve the emergence rate,root-shoot ratio and chlorophyll content of rice seedlings,improve the quality of rice seedlings,grow neatly,and finally form large panicles.Under the same cultivation conditions,the strong seedlings were easy to obtain high yield,that is,the coating agent treatment could effectively increase the yield.
