采用L16（44）正交试验研究香蕉有机质肥、钾肥、镁肥、硼肥不同水平间的配施效果。结果表明,在土壤有机质含量适宜、钾素和镁素含量丰富、硼素较缺乏的香蕉园,以氮（年株N 0.4 kg）、磷（P2O50.16 kg）施用量固定的条件下,香蕉年株施氯化钾1.335 kg＋硫酸镁75 g＋硼砂0.2%溶液喷1遍（不施有机肥）产量最高,其N∶P2O5∶K2O为1.0∶0.4∶2.0;年株施氯化钾1.0 kg（不施有机肥、镁肥和不喷硼）肥效最好,667 m2净利润2 559.6元,投入产出比1∶1.89,其N∶P2O5∶K2O为1.0∶0.4∶1.5。有机质肥对增产作用不大,但可改善果肉品质。在土壤镁素含量丰富的香蕉园,不宜盲目增施镁肥;在土壤硼素较缺乏的香蕉园,每年喷1遍硼砂0.2%溶液。

The paper studies effects of the mixture with different proportion of organic fertilizer,potassium fertilizer,magnesium fertilizer and boric fertilizer on Banana,using orthogonal trial of L16（44）.The result showed that in a banana plantation with suitable organic content,plentiful potassium and magnesium content and lacking boron content in soil,under the condition of N fertilized 0.4 kg and P2O5 fertilized 0.16 kg per tree per year,the output was best in case banana tree is applied 1.335 kg KCl,75 g magnesium sulfate,and sprayed by 0.2% borax solution one time（no organic fertilizer） per year,here N ∶ P2O5 ∶ K2O=1.0 ∶ 0.4 ∶ 2.0;fertilizer benefit is best in case Banana tree is applied 1.0 kg KCl per year（no organic fertilizer,no magnesium sulfate and no 0.2% borax solution）,667 m2 net profit is 2 559.6 RMB yuan,input-output ratio is 1 ∶ 1.89,and N ∶ P2O5 ∶ K2O=1.0 ∶ 0.4 ∶ 1.5.Effects of organic fertilizer on increase production is not obvious,but it is good for pulp quality.In a banana plantation with plentiful magnesium content in soil,magnesium fertilizer should not be applied blindly;In a banana plantation with lacking boron content in soil,0.2% borax solution should be applied one time per year.
