花卉植物种子播种手册很多花友手中的花卉种子大多是分享来的或者是在市场购买来的但在花谈上的花友多数是业余种殖并非都是搞专业园艺。所以大家只要掌握播种温度、出芽时间和种子发芽需光性这三个要素就可以了在这三个要素中特别要注意前两项。提高花卉种子出苗率是一项技术性很强的工作要想提高花卉种子的出苗率应先了解影响出苗率的原因以便合理进行处置。现在我来大致解释这三个要素内容。种子播种温度:种子的发芽除必须有一定水分条件外还必须具备一定的温度才行。温度太高或太低都会影响种子出苗率尤其会引起种子霉烂、腐烂现象的发生大大降低了种子的发芽率和成苗率。所以大家要对播种温度严格把握,我国地域辽阔各地区的气温相差也大,花友们在参加分享或购买种子时一定要根据自己所在地的气象条件而定,不可盲目播种种子出芽时间:各种花卉植物的种子萌芽时间是有差异的而我们要做的是如何打破种子休眠时间,有些花卉如流苏、芍药等的种子具有胚根和胚轴双休眠的特性即其胚根需要通过至个月或更长时间℃至℃的高温阶段才能打破休眠。如我去年给大家分享的进口石榴种子必需在度以上和天左右时间才能打破种子的休眠但很多花友拿到种子马上就开始播种,结果用了二个多月还没有唤醒种子三个要素中和很重要请大家务必把握好。。发芽需光性:光照可增加土壤的温度诱发种子发芽尤其对种子穿破种皮出根露芽更为重要。它不但影响种子的出苗率也直接关系到能否长出好苗、壮苗。因此从播种到移苗阶段应是一个从阴暗到弱光再到自然光照的过程应根据播种、发芽、出苗的不同阶段尽量满足花卉生长对光照的需要。在手册中标明的覆土就是覆盖土壤至厘米左右。覆薄土就是覆盖土壤厘米左右稍盖土就是覆盖土壤厘米左右不敏感就是种子出芽时对光照强度的反应不强烈,光弱不会引起苗木的徒长嫌光如韭菜、苋菜、番茄、它们在光下萌发不好,而在黑暗中反而发芽很好,这类种子称喜暗而需光就是种子出芽后一定要有良好的光照强度,否则会引起苗木的徒长花谈ID:草萌芽花毛茛香雪球度周发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性不敏感嫌光度天度约一周不敏感度天嫌光天天需光发芽光性度天不敏感度天需光度天需光草萌芽发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性嫌光度一周左右度约二周度天嫌光度天不敏感发芽光性度天需光度天稍覆土度天不敏感福禄考度嫌光美女樱嫌光康乃馨石竹天满天星剪秋罗羽叶甘蓝花亚麻草萌芽发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性不敏感度天度天度天不敏感度天需覆薄土发芽光性度天需光度天不敏感度天不敏感角堇度嫌光三色堇嫌光古代稀月见草天补血草勿忘我洋桔梗风铃草草萌芽发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性需光度天度天度天不敏感度天不敏感发芽光性度天不敏感度天不敏感度天嫌光金鱼草度需光香豌豆需覆薄土羽扇豆四季秋海棠天蒲包花旱金莲六倍利蛇鞭菊左右草萌芽发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性需光度天度天度天不敏感度左右天发芽光性度天嫌光度天度左右天西洋报春度需光四季报春需光翠菊雏菊天多花报春轮锋菊金盏菊矢车菊需光需光嫌光草萌芽发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性度天度天度天不敏感度天发芽光性度天需光度天嫌光度天金光菊度松果菊需光黑心菊五色菊天红晶菊瓜叶菊大滨菊仙客来需光需光需光需光草萌芽发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性度天度天度天不敏感月初发芽迅速发芽光性度天需光度天稍覆土度天向日葵度大丽花稍覆土地肤雁来红鸡冠花千日红紫茉莉太阳花需光覆土cm覆土天嫌光草萌芽发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性度天度天度天度天发芽光性度天需光度天度天醉蝶花度覆土含羞草凤仙花朝天椒一周左右银边翠黄秋葵马络葵蜀葵覆薄土不敏感覆薄土覆土需光覆薄土草萌芽发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性度以上天度天度天不敏感度天发芽光性度天需光度天度天长春花度一串红需光毛地黄波斯菊天红花天人菊麦杆菊孔雀草需光略覆土需光略覆土需光草萌芽发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性发芽光性度以上天度天度天度天发芽光性度天度天度天葫芦度石榴需光牵牛玩具南瓜天薰衣草绸缎花金盏菊茑萝略覆土略覆土略覆土略覆土略覆土覆土覆土草萌芽花卉植物种子播种手册pdfapdf页面apdf页面apdf页面apdf页面apdf页面apdf页面apdf页面apdf页面apdf页面apdf页面<<ASCIIEncodePagesfalseAllowTransparencyfalseAutoPositionEPSFilestrueAutoRotatePagesAllBindingLeftCalGrayProfile(DotGain)CalRGBProfile(sRGBIEC)CalCMYKProfile(USWebCoatedSWOPv)sRGBProfile(sRGBIEC)CannotEmbedFontPolicyWarningCompatibilityLevelCompressObjectsTagsCompressPagestrueConvertImagesToIndexedtruePassThroughJPEGImagestrueCreateJDFFilefalseCreateJobTicketfalseDefaultRenderingIntentDefaultDetectBlendstrueDetectCurvesColorConversionStrategyLeaveColorUnchangedDoThumbnailsfalseEmbedAllFontstrueEmbedOpenTypefalseParseICCProfilesInCommentstrueEmbedJobOptionstrueDSCReportingLevelEmitDSCWarningsfalseEndPageImageMemoryLockDistillerParamsfalseMaxSubsetPctOptimizetrueOPMParseDSCCommentstrueParseDSCCommentsForDocInfotruePreserveCopyPagetruePreserveDICMYKValuestruePreserveEPSInfotruePreserveFlatnesstruePreserveHalftoneInfofalsePreserveOPICommentsfalsePreserveOverprintSettingstrueStartPageSubsetFontstrueTransferFunctionInfoApplyUCRandBGInfoPreserveUseProloguefalseColorSettingsFile()AlwaysEmbedtrueNeverEmbedtrueAntiAliasColorImagesfalseCropColorImagestrueColorImageMinResolutionColorImageMinResolutionPolicyOKDownsampleColorImagestrueColorImageDownsampleTypeBicubicColorImageResolutionColorImageDepthColorImageMinDownsampleDepthColorImageDownsampleThresholdEncodeColorImagestrueColorImageFilterDCTEncodeAutoFilterColorImagestrueColorImageAutoFilterStrategyJPEGColorACSImageDict<<QFactorHSamplesVSamples>>ColorImageDict<<QFactorHSamplesVSamples>>JPEGColorACSImageDict<<TileWidthTileHeightQuality>>JPEGColorImageDict<<TileWidthTileHeightQuality>>AntiAliasGrayImagesfalseCropGrayImagestrueGrayImageMinResolutionGrayImageMinResolutionPolicyOKDownsampleGrayImagestrueGrayImageDownsampleTypeBicubicGrayImageResolutionGrayImageDepthGrayImageMinDownsampleDepthGrayImageDownsampleThresholdEncodeGrayImagestrueGrayImageFilterDCTEncodeAutoFilterGrayImagestrueGrayImageAutoFilterStrategyJPEGGrayACSImageDict<<QFactorHSamplesVSamples>>GrayImageDict<<QFactorHSamplesVSamples>>JPEGGrayACSImageDict<<TileWidthTileHeightQuality>>JPEGGrayImageDict<<TileWidthTileHeightQuality>>AntiAliasMonoImagesfalseCropMonoImagestrueMonoImageMinResolutionMonoImageMinResolutionPolicyOKDownsampleMonoImagestrueMonoImageDownsampleTypeBicubicMonoImageResolutionMonoImageDepthMonoImageDownsampleThresholdEncodeMonoImagestrueMonoImageFilterCCITTFaxEncodeMonoImageDict<<K>>AllowPSXObjectsfalseCheckComplianceNonePDFXaCheckfalsePDFXCheckfalsePDFXCompliantPDFOnlyfalsePDFXNoTrimBoxErrortruePDFXTrimBoxToMediaBoxOffsetPDFXSetBleedBoxToMediaBoxtruePDFXBleedBoxToTrimBoxOffsetPDFXOutputIntentProfile()PDFXOutputConditionIdentifier()PDFXOutputCondition()PDFXRegistryName()PDFXTrappedFalseDescription<<CHS<FEFFfffdebbbebabefaefafccacfffdbcaddcfaefeefffcfeeecafadcfbefa>CHT<FEFFffebadfeefaacbfefefcafcffeafadcceacaefeefffcfeeecafadcfbfdfefaacbef>DAN<FEFFecceecffdfbdecbcbeeccbfbceeeefdfbdebeeefccfefee>DEU<FEFFeeecceeadccefefdfbdeecfeeefbbfdbeeffdeeaedfeeccdfbdebfeeedfefefffeee>ESP<FEFFcfefefdefffedfecedfffdeffeeefdefffefcfefeffe>FRA<FEFFcaffeeefdeffedfeceddeecfdeeeeeafefcefefecee>ITA<FEFFcaadfafefdefedcedeffbfefdeffeffeffefee>JPN<FEFFadcceafabffefcbffeebceabfddcdecbafccddeafbfeeffdebfcdbeeadbafc
