摘要
平衡施肥能改善重茬大豆幼苗的生理性状 ,使大豆主根长增加 ,侧根数增多 ,根系活力增强 ,总根长增加、叶面积增大、叶绿素含量增加、光合作用增强 ,大豆地上、地下部干重显著增加 。
Balanced fertilizer applicaton can adjust physiological properties of continuous cropping soybean seedling,causing its main root leugth,branch-root number,total root length,content of chlorophyll inereased,activity of root system and photosynthesis strengthened,and its dry weight of shoot and root increased significantly.The effect of fertilizer of combination of NPK and micro-element is the best.
