摘　　要：[目的]寻找适合苎麻施用的叶面肥。[方法]通过田间试验和室内试验研究不同叶面肥在不同时间、不同土壤喷施对苎麻生理生化特性的影响。[结果]喷施腐植酸类叶面肥可显著提高苎麻的可溶性糖、硝酸还原酶、过氧化物酶和过氧化氢酶的活性。从试验地点来看,新屋杨苎麻各参数的增幅相对较少,而牛角畈的增幅较大。从叶面肥的品种来看,丰收素施用效果优于其他两种。施用腐植酸类叶面肥能够促进作物根系生长,从而有效地利用深层土壤的养分与水分,能够促进作物茎叶生长,显著增加苎麻产量,提高产品品质,提高农民收入。[结论]叶面肥具有广阔的市场应用前景。[ Objective ] The aim was to search for the suitable foliar fertilizer for Boehmeria nivea. [ Method] The effect of different foliar fertilizers spraying in different times and on different soils on physiological and biochemical characteristics of B. nivea were studied by the field experiment and laboratory test. [ Result] Spraying humic acid foliar fertilizers could increase the activities of the soluble sugar, nitrate reduetase, peroxidase and catalase of B. nivea. From the test place, the amplitude of each parameter of B. nivea in Xinwuyang was less relatively and that in Niujiaoban was larger. From the foliar fertilizer variety, the application effect of Fengshousu was better than that of the other two varieties. Applying humic acid foliar fertilizers could promote the crop root growth and utilize the nutrient and water in the deep soil. It also could promote the crop stein and leaf growth and increase the yield and the quality of B. nivea, which could raise the income of peasant. [ Conclusion] The foliar fertilizer had broad market application prospect.
