剑麻不仅能耐长期干旱,而且能在瘠地生长。因此,人们常以为它是一种很粗放的作物。然而,剑麻大面积栽培既需充足和分布均匀的雨量,又需能使植株速生高产的肥力。剑麻的最适年雨量为1,250—1,750毫米,但持水力良好的厚层土壤有助于弥补雨量的不足。在较干旱条件下,新叶抽生缓慢并可能呈间歇性生长,使生命周期延长。
Sisal is not only resistant to long-term drought, but also grows in barren land. Therefore, people often think it is a very thick crop. However, large-area sisal cultivation requires adequate and well-distributed rainfall as well as the fertility needed to make plants faster and more productive. The optimum annual rainfall for sisal is 1,250-1,750 mm, but a thick, well-hydrated soil helps to make up for the lack of rainfall. In more dry conditions, new leaflets are slow to breathe and may intermittently grow, prolonging the life cycle.
