摘要
通过研究不同钾肥施用量对山槐苗木生长的影响,表明钾肥对山槐苗木生长有很大的促进作用,能明显地提高幼苗的苗高、地径、主根长、侧根数和生物量等指标,特别是对根系的促进作用最大。不同钾肥施肥量对山槐苗木生长的影响存在显著性效应,在施用15 g/m2钾肥时,山槐各项生长指标表现最优,苗木质量最好。
This paper studied the effect of different potassium fertilizer application on the seedling growth of M. amurensis.The results showed that potassium had a great role in promoting the growth of M. amurensis. seedling index,they can significantly improve the seedling height,ground diameter,root length,lateral root number and biomass,especially for the root. Effects of different fertilization on the growth of seedlings had significant effect. When using 15 g / m2 potassium fertilizer,the growth index was the best,and the seedling quality was the best.
