调查结果表明,我国植麻区的土壤肥力大都较低,不能满足剑麻高产的需要。要获高产,需大量施肥。现有麻田的营养水平差异较大:氮变化在0.45～1.73%之间,平均0.83%;磷变化在0.04～0.37%之间,平均0.13%;钾0.16～3.36%,平均1.73%;钙0.90～5.49%,平均2.81%;镁0.13～1.78%,平均0.71%。并有缺钾、缺硼和缺镁等营养失调症出现。建议推广营养诊断法指导施肥。

The survey results show that the soil fertility of our plantation area is mostly low, can not meet the needs of high yield sisal. To get high yield, need a lot of fertilizer. The available nutrient levels of Matian are quite different: the variation of nitrogen is between 0.45 and 1.73% with an average of 0.83%; the variation of phosphorus is between 0.04 and 0.37% with an average of 0.13%; potassium 0.16 ~ 3.36% with an average of 1.73%; Ca 0.90 ~ 5.49%, an average of 2.81%; magnesium 0.13 ~ 1.78%, an average of 0.71%. And potassium deficiency, lack of boron and magnesium and other nutritional disorders appear. Recommended to promote nutrition diagnosis guidance fertilization.
