不同种植模式对芭蕉芋产量的影响

Study on the Effect of Different Cropping Patterns on the Yield of Banana Dasheen

[目的]比较2种种植模式对芭蕉芋生长和产量的影响。[方法]以6个地方和省外芭蕉芋品种为试材，采用行栽和窝栽种植模式进行小区比较试验，观察各品种的生长情况。[结果]与窝栽种植相比，行栽种植下，芭蕉芋的株高、分蘖数、茎节数和叶片大小等性状好，产量可增加4501．0～16132．5kg／hm2，增幅在1．9％一21．9％。在2种种植模式下，云南富源县的红花和贵州安龙县的黄花2个品种的产量未达到显著差异；云南富源县的黄花和贵州兴义县的黄花2个品种的产量达到显著差异；云南富源县的红花和贵州兴义县的红花（CK）2个品种的产量达到极显著差异。[结论]行栽的种植模式较窝栽有利于芭蕉芋的萌发和分蘖，有利于改善土壤的通透条件及理化性质，从而增加芭蕉芋的产量。

[Objective] The aim was to compare the effects of 2 cropping patterns on the growth and yield of banana dasheen. [Method] With 6 banana dasheen varieties in local places and from other provinces as tested materials, the plot comparative test was carried out by using crop- ping patterns of row planting and hole planting to observe the growth status of each variety. [ Result ] Compared with hole planting, the characters of plant height, tiller number, eustipes number and leaf size etc. of banana dasheen were good in row-planting, the yield could be raised by 4 501.0 - 16 132.5 kg/hm2 with the increasing amplitude between 1.9% and 21.9%. Under 2 cropping patterns, the yields of 2 varieties of Honghua in Fuyuan County, Yunnan and Huanghua in Anlong County, Guizhou didn＇ t reach to significant difference ; the yields of 2 varieties of Huanghua in Fuyuan, Yunnan and Huanghua in Anlong, Guizhou were up to obvious difference ; the yields of 2 varieties of Honghua in Fuyuan, Yunnan and Honghua （CK） in Anlong, Guizhou were up to extremely significant difference. [ Conclusion] Compared with holeplanting, the cropping pattern of row-planting was in favor of germination and tiller of banana dasheen, and was beneficial to the improvement of permeating conditions and physicochemical properties of soil, so as to increase banana dasheen yield.
