如何清除沙糖桔果园的竹仔头?内容摘要:
2、属于禾本科植物的属性,用灭活性 10草甘膦喷施于新抽发的竹鞭上,药剂活性物质被吸收后传导到竹头根系上,阻碍根系蛋白的合成,在一定程度上有抑制效果,使用浓度建议在 2000 毫升对水 30 公斤。 如果在上述配种加入 7220 毫升,估计效果会更好。 此外,用灭生性 20百草枯(克无踪)200 毫升对水 50 公斤,在竹鞭长出约高25 厘米时喷施破坏其光合作用,使竹头根系在缺少光合产物支持的情况下受抑制。 但百草枯没有灭活根系的能力,只能破坏植物叶绿素的合成。 因此需要经过反复数次施药,才能逐步使竹头根系最终因缺失营养而枯死。 但喷药时要注意不要使药液飘移到果树树冠,以免造成不必要的损失,请参考。 专利查询。如何清除沙糖桔果园的竹仔头?
