摘　　要： 通过选点取样对剑麻营养元素的测定,利用数理统计分析的方法,分析养分间、养分与经济性状间的相关关系。得出以下结论:增施N、P、Zn将导致剑麻叶片产量、单叶纤维重、单叶重、纤维产量的显著或极显著提高;增施Ca、Si虽可促进单叶重显著提高,但将导致纤维率的显著下降,增施K将导致纤维率的显著下降,因此,应注意麻田的合理施肥。 By evaluating the nutrient content of low, mid and high yielding sisal hemp planting soils and its role to sisal hemp agronomical characters statistically, the following observations couldbe drawn. If more N, P, Zn were added to the field of sisal hemp, the leaf yield, single leaf fibre weight, single leaf weight and fibre yield would increase notably or extremely notably. If more Ca, SiO2 were added, though it could increase the weight of single leaf remarkably, it would cause remarkable decline of fibre rate. If K was added, the fibre rate would decrease strikingly. Therefore attention should be paid to rational application of fertilizers to the field of sisal hemp.
