| 摘 要： | 目的]探索芭蕉芋与玉米的合理套作模式,提高种植效益。方法]紫叶红花芭蕉芋200cm×60cm×50cm、230cm×60cm×50cm、250cm×60cm×50cm双行双株沟植,行间60cm×50cm双行双株套作紫糯1号玉米,以170cm×60cm双行穴植芭蕉芋、行间60cm×50cm双行双株套作玉米为对照,研究不同套作模式对芭蕉芋萌芽率、分蘖数及作物产量和经济效益的影响。结果]3种套作模式芭蕉芋的萌芽率分别为61.0%、61.0%、65.9%,均高于对照（58.9%）;收获期分蘖数分别为11.6、12.5和10.3个,分别比对照增加38.1%、48.8%、22.6%。230cm×60cm×50cm套作模式下,芭蕉芋产量为66405kg/hm2,鲜糯玉米产量为9435kg/hm2,纯收益为31650元/hm2,分别比对照增加41.8%、50.8%和87.7%。结论]230cm×60cm×50cm为芭蕉芋套作玉米的合理模式。

| Abstract: | Objective] The purpose was to explore the reasonable intercrop pattern of Canna edulis Ker and corn and enhance planting benefit.Method] A cultivar with purple leaves and red flowers of C.edulis was planted in double-row and double-plant trench planting patterns of 200 cm×60 cm×50cm,230 cm×60 cm×50 cm and 250 cm×60 cm×50 cm resp.and the corn Zinuo1 was intercropped in double-row and double-plant pattern of 60 cm×50 cm in inter-row.In the control pattern,the C.edulis was planted in hole-planting and double-row pattern of 170 cm×60 cm and the corn was intercropped in double-row and double-plant pattern of 60 cm×50 cm in inter-row.Then the influences of different intercrop patterns on the germination rate and tillering number of C.edulis and crop yield and economic benefit were researched.Result] In 3 intercrop patterns,the germination rates of C.edulis were 61.0%,61.0% and 65.9%,being higher than 58.9% of CK;their tillering numbers of harvest period were 11.6,12.5 and 10.3 resp.and being increased by 38.1%,48.8% and 22.6% resp.in comparison with CK.In the intercrop pattern of 230 cm×60 cm×50 cm,the yields of C.edulis and fresh glutinous corn were 66 405 and 9 435 kg/hm2 and the pure benefit was 31 650 yuan/hm2,which were increased by 41.8%,50.8% and 87.7% resp.Conclusion] The reasonable intercrop pattern of C.edulis and corn was 230 cm×60 cm×50 cm. |
