淮南地区冬、春季温室大棚莴苣培养技术探索 养殖学专业VIP免费

淮南地区冬、春季温室大棚莴苣培养技术探索摘要大棚莴苣栽培的产量高而稳定，一般来说大部分的大棚栽培位于江淮地区大棚生产期短且不需要任何的加温设备。莴苣是一年或者二年的生长性植物，它的本生产地是地中海沿岸喜好湿润的气候，并且莴苣是华南地区在冬季和春季最主要的蔬菜之一。一般来说篇筐可分为两个种类一种是叶用莴苣，另一种是茎用莴苣。莴苣的口味极好，而且营养非常的丰富，是人们较为喜爱的蔬菜，具有较高的经济价值。文章针对近年来，大棚莴苣种植的快速发展出现品种老化、主栽品种不突出，莴苣杭性下降、丰产性不高，导致商品质量竞争力不强等，不能适应生产的需求问题。引进适合地理、气候条件的新品种，以更新主栽品种，对促进莴苣种植产业的发展具有十分重要的现实意义本文结合理论，主要从选种、大棚修剪、定植前后准备、病虫害防治以及及时采收等方面对大棚莴苣栽培技术做了介绍，以期为广大种植户提供参考。关键词：大棚莴苣；栽培；技术AbstractTheyieldoflettucecultivationingreenhouseishighandstable.Generallyspeaking,mostofthegreenhousecultivationislocatedintheJianghuaiarea,wherethegreenhouseproductionperiodisshortandnoheatingequipmentisneeded.Lettuceisagrowingplantforoneortwoyears.ItisproducedinahumidclimatealongtheMediterraneancoast.LettuceisoneofthemostimportantvegetablesinwinterandspringinSouthChina.Generallyspeaking,thebasketcanbedividedintotwokinds,oneisleaflettuce,theotherisstemlettuce.Winterandspringnestheadcultivationhashigheconomicvalue.TocarryoutresearchonHigh-yieldCultivationTechniquesofbiologicalcharacteristicsofwinterandspringnestheadcaneffectivelyimprovethegrowthqualityofwinterandspringnestheadandbringconsiderableeconomicincometovegetablefarmers.Huainanareahasgoodnaturalconditionsforthegrowthofwinterandspringnesthead.Toensurethehighandstableyieldofwinterandspringnesthead,weshoulddoagoodjobintheselection,sowing,germinationpromotion,fertilization,wateringandpestcontrolofwinterandspringnesthead.Lettuceisafavoritevegetablewithexcellenttasteandrichnutrition.Ithashigheconomicvalue.InviewoftherapiddevelopmentoflettucecultivationinGreenhouseinrecentyears,theproblemsofagingvarieties,notprominentmaincultivars,decliningHangzhoucharacterandlowyieldoflettucehavearisen,whichleadtopoorcompetitivenessofcommodityqualityandcannotmeettheneedsofproduction.Introducingnewvarietiessuitableforgeographicalandclimaticconditionstoupdatethemainvarietiesisofgreatpracticalsignificanceforpromotingthedevelopmentoflettuceplantingindustry.Basedonthetheory,thispapermainlyintroducedthecultivationtechniquesoflettuceingreenhousefromtheaspectsofseedselection,greenhousepruning,preparationbeforeandafterplanting,pestcontrolandtimelyharvesting,inordertoprovidereferenceforfarmers.Keywords:lettuceingreenhouse;cultivation;Technology目录摘要..............................................IAbstract.........................................II引言..............................................11温室莴苣生产现状.................................12大棚莴苣栽培技术.................................32.1莴苣品种选择...................................32.2大棚修建.......................................32.3育苗...........................................32.3.1播种准备.....................................42.3.2播种.........................................42.3.3育苗管理.....................................42.4生长期管理.....................................52.4.1定植管理.....................................52.4.2植株调整.....................................62.4.3科学使...
