俗话说:“命根相连”。棉花移栽后缓苗,其根本原因在于损伤根系以及其它因素的影响,使根系吸收机能破坏,水分循环失去平衡。因此只有尽量减少根系损伤,同时采取能促新根迅速伸长、恢复根系吸收机能的综合措施,才能有效地减轻缓苗过程。1.培育壮苗,严格锻炼,是减轻缓苗争早发的基础各地实践证明,壮苗成活率高,缓苗轻,
As the saying goes: “lifeblood connected ”. Hibiscus seedlings after transplanting cotton, the root cause is damaged roots and other factors, so that the destruction of the root absorption function, the water cycle out of balance. Therefore, only to minimize root damage, while taking to promote rapid root elongation and restore root absorption function of comprehensive measures to effectively reduce the Huanmiao process. 1. Nurturing strong seedlings, strict exercise, is to reduce the slow onset of early onset of mitigation around the proven practice, strong seedling survival rate, Huanmiao light,
