摘　　要：采用"3414"设计方案进行田间实验,在实验观测的基础上,建立了中肥不同生育期巴西香蕉叶面积与叶长、叶宽及长宽乘积之间的定量关系,结果表明:不同生育期,巴西香蕉叶面积与叶长、叶宽及长宽乘积最佳模型Y=ax+b,具体关系如下:在营养生长期中,叶面积与叶长、叶宽及长宽乘积间定量关系分别为:A=-2 162+54.957 L、A=-2 202.687+123.919 W、A=-76.014+0.767 P;孕蕾期及抽蕾期,叶面积与叶长、叶宽及长宽乘积间定量关系分别为:A=-6 969+90.584 L、A=-6 971+231.195 W、A=-38.177+0.778 P。经2012～2013年独立资料检验:营养生长期高、低肥叶面积的模拟值与观测值的差值标准误分别为298.098、356.456和232.127 cm2/株,孕蕾期及抽蕾期高、低肥叶面积的模拟值与观测值的差值标准误分别为1 134.310、3 584.610和1 306.924 cm2/株,检验结果表明:所建的香蕉叶面积模型可靠性均较好,具有一定的解释性和通用性,对香蕉理想株型设计、结构与功能关系研究及香蕉生长系统的可视化和数字化均有一定的参考价值。Based on field experiments, the quantitative relationships of Brazil banana between leaf area and leaf length, leaf width, leaf lengthxleaf width under different developing stages under middle fertilizer applicaton were studied. The results showed that the best model of quantitative relationship above was Y=ax＋b. At the vegetative growth period, the above relationship was A=-2 162＋54.957 L, A =-2 202.687＋123.919 W, A=-76.014＋0.767 P, respectively. And at the bud formation stage or budding stage, the above relationship was A =-6 969＋90.584 L, A=-6 971＋231.195 W, A=-38.177＋0.778 P, respectively. The test results for independent samples of 2012-2013 are satisfactory. At the vegetative growth period, the standard error of difference between simulated value and measured value of leaf area under high and low fertilizer was 298.098, 3 56.456 and 232.127 cm2/plant, respectively. Then at the bud formation stage or budding stage, the above SE of difference was 1 134.310, 3 584.610 and 1 306.924 cm2/plant, respectively. The result showed that the leaf area model of Brazil banana was interpretive and commonality. The model has certain reference value for Brazil banana＇s ideotype selection, the research of its structure-function relationship and the virtualization and digitalization of its growth system.
