摘　　要：本文研究了席草施肥对土壤电导率（ＥＣ）的影响。结果表明：划分为１次基施和５次追施的各累积施肥量与其相对应的ＥＣ呈极显著的线性回归关系（ｒ≥０．８８４２，ｎ＝１１）；肥料用量影响了主要生育时期ＥＣ值的升降幅度和鲜草产量；鲜草产量与成熟期前后的ＥＣ值呈极显著的指数回归关系（ｒ＝－０．８４７１，ｎ＝２０）。It was studied that effect of dressing fertilizer to so soil electrical conductiveity(EC)on rush in thispaper .The results showed that results showed that relationship between every accumulative dressing fertilizer rations after which weredivided into a basal dressing and 5 times top drersing and corresponding soil EC had all very significant linear re-gression(r≥0. 8842,n=11).And fertilizer rations affected fresh stem yields and rangr of increase and de-crease of soil EC in main growth porids,And the relationship between the yields and EC in after and before of har-vest poried had very signiticant indexical regression(r =-0.8471,n=20).
