摘　　要：调查剑麻主产区土壤理化性质、叶片养分含量和剑麻化肥施用等情况,发现我国剑麻主产区麻园土壤碱解氮含量适中,有效磷含量偏高,速效钾含量较高,土壤交换性钙、镁含量偏低;剑麻叶片全N、全K含量偏高,全Ca、全Mg含量偏低;化肥施用量大、化肥利用率低、化肥施用成本高。认为剑麻施肥应以减N稳P减K,补Ca补Mg为原则,以化肥为主,有机肥为辅。This study investigated the current situation of the physical and chemical properties of soil,nutrient content of leaves,and fertilizer application of sisal in the main sisal producing areas.It is found that the content of the alkali hydrolyzable nitrogen of soil is moderate,the content of the available phosphorus is higher,the content of available potassium is high,and the content of the exchangeable calcium and magnesium in the soil is lower;The content of the total N and K in sisal leaves are higher,while the content of the total Ca and Mg are lower;The applicative amount of fertilization is large,the utilizable rate of fertilizer is low,and the applicative cost of fertilizer is high.We should follow the guideline of reducing N,stabilizing P,declining K,supplementing Ca and Mg,with the fertilizers as the mainstay and the organic fertilizers as a supplement.
