文档介绍：苎麻低位分枝扦插苗生长发育特性研究摘要以高产优质苎麻品种中苎一号为材料,研究了扦插苗打顶处理对苎麻低位分枝苗生长发育特性的影响。结果表明:嫩梢扦插打顶处理可明显增加根系干重和根系体积,减少主茎高度和主茎干重,增加主茎粗度、单株叶片数和叶面积;同时可影响分枝的生长发育,培育出相对较低最低分枝位、最高分枝位和较短分枝位长,促进分枝数、分枝平均长度和分枝干重明显增加。就扦插苗打顶时间而言,扦插时打顶处理明显要优于插后1周打顶处理。本文来源于网络,本站发布的论文均是优质论文,供学****和研究使用,文中立场与本网站无关,版权和著作权归原作者所有,如有不愿意被转载的情况,请通知我们删除已转载的信息,如果需要分享,请保留本段说明。关键词苎麻;低位分枝扦插苗;-5739(2010)17-0047-03 StudyontheCharacteristicsofGrowthandDevelopmengofCuttingPlantforLowBranchesinRamie HEZai-xin1,2MENGGui-yuan1,3SUNHuan-liang1*ZHOUQing-ming1HEYong1 (1CollegeofAgriculture,HunanAgricultureUniversity,ChangshaHunan410128;2HuaihuaVocationalTechnologyCollege;3HunanInstituteofHumanities,ScienceandTechnology) AbstractWithhighqualityramievarietiesZhonhgzhuNo1asmaterial,,reducedmainstemheightandmainstemdryweight,andincreasedthedegreeofthemainstemdiameter,,thedecapitationtreatmentcouldinducegrowthanddevelopmentofbranchingcharacteristics,nurturerelativelylowminimumbranchingbit,theshorthighestbranchbitandbranchbitslength,andpromotesignificantlytheincreaseofbranchesnumber,,thecuttingswhe
