【摘要】 对香蕉群体质量评价指标的研究结果表明,为培育香蕉高产、优质群体,应从协调源、库、流关系入手进行栽培管理,即抽蕾期群体应具有适宜的叶面积指数,采收期需维持一定的绿叶数和绿叶总面积,形成最大的产量源,从而提高抽蕾后光合生产量;提高倒数第3～7叶在群体叶面积指数中的比例,增加总果指数及单果重,培育大果穗,扩大库容量,从而增加结实期光合积累量;增加假茎粗度,提高果茎比,增加穗柄粗度,控制一定穗柄长度,协调源、库关系,维持光合产物运转流畅。更多还原

【Abstract】 The evaluation of population quality indices in banana showed that the cultivation of high yield and quality population in banana should coordinate the relationships among the source,sink and flow.During the period of bud emergence the leaf area index of the population should be suitable,and during the period of harvest the number and area of green leaves should be maintained to form the biggest yield source and improve the photosynthetic production after the period of bud emergence.The ratio of the reciprocal 3～7 leaves in the population leaf area index should be increased,the total numbers and weight of banana fingers should be increased to breed big fruit bunches and increase the sink capacity to increase the photosynthetic accumulation of population during ripening period.The pseudostem girth and peduncle girth,the ratio of fruit and stem should be increased and the peduncle length should be controlled to coordinate of source,sink and flow.更多还原
