2、产量相关性状的影响,为福建龙岩红芽芋高产栽培提供科学依据。以福建龙岩红芽芋为材料,采用不同肥料配施、种植密度、覆盖方式、品种比较和芋膨大期观察试验。基肥(有•机肥500kg/667m2)+屮期(有机肥500kg/667m2)冇利于获得高产,综合品质最好;密度(40cmx60cm)产量最高;地膜覆盖町明显提高植株高度、叶宽、叶长、成叶数、茎慕粗度、了芋与孙芋重量;红芽芋子芋重量和产量在芋膨大屮期(7月14H)具有明显的快速增长现象;适当增加株高和茎叶产量有利于母芋产量的增加,母芋产量的增加有利于子芋个数与产量、孙芋个数与产量的增加,从而获得较高的产量。因
3、此,采用综合栽培技术可显著提高龙岩红芽芋产量和品质。关键词:红芽芋;产最性状;栽培技术;相关通径中图分类号:S632.3文献标识码:AAffectsofDifferentCultivationTechniqueMeasuresonYield-relatedTraitsofRedSproutClocasiaescalentainLongyanFujianLaiYonghong(XinluoDistrictSeedAdministrationStation,LongyanFujian364000)Abstract:Todiscusstheeffectsof
