种植密度对香蕉生长及产量的影响

以"巴西"香蕉为材料，研究种植密度对香蕉生长及产量的影响。结果表明不同密度下茎高、茎周、绿叶数、叶面积相对增长率拐点值各不相同;不同密度下茎高、茎周、叶长、叶宽、果指数、果穗轴直径、果指长度之间无显著差异，而吸芽数随种植密度的增加而减少;单株产量随密度的增加而减小;单位面积（公顷）产量以种植密度3125株（1.6m>2.0m）最高，为89687.5kg，同时单位面积产量随种植密度的增加而增加，差异极显著。

Effects of Planting Densities on the Growth and Yield of Banana

China Abstract Banana variety"Brazil"usa spp.)was panted in various densities to observe theireffects on is grow th and productivity.Results show ed that the plantheight, pseudostem diameter,leaf number, and the relative growth rate of leaf area varied under different planting densities. But the plant height, pseudostem dimeter, leaf length, laf width, num berof fuit fingers percluster,fuitstak diameter and the length of fuit fingers were notsinificanty diffrentunder differentplanting densities.However, this variety was bow in num ber of suckers per plant and yield perplant, butvery significantly higher in yield perhectare under high panting densitis.The highestyield was89 687.5kghaathe plant ing density of3125 plant1.6m>2.0m).
