1、http://www.tswuyuehua.net/http://www.lczxdz.com/探析不同育苗基質(zhì)對黃瓜幼苗生長的影響摘要:以腐熟中藥渣、泥炭、蛭石、珍珠巖為原料,按照不同比例復(fù)配成4種育苗基質(zhì),選取南京市蔬菜所的通用型育苗基質(zhì)作為對照,研究不同配比的育苗基質(zhì)對黃瓜苗期生長的影響。結(jié)果表明:基質(zhì)B培育的黃瓜在株高、莖粗、根長、根表面積以及壯苗指數(shù)上均顯著優(yōu)于其他配比的育苗基質(zhì),育苗效果顯著提高,可推薦作為黃瓜育苗的專用型育苗基質(zhì)。Abstract:therotteninthemedical,peat,vermiculite

6、eriously. 育苗是蔬菜栽培的重要措施,育苗基質(zhì)則是穴盤種苗生產(chǎn)的基礎(chǔ)物質(zhì),而基質(zhì)良好的理化性狀直接影響秧苗的壯弱,從而影響到蔬菜的長勢和產(chǎn)量。但是傳統(tǒng)的育苗方法,具有土傳性病害嚴重、成活率低、緩苗期長、生長發(fā)育慢等缺點[1],已無法滿足發(fā)展日益快速的農(nóng)業(yè)生產(chǎn)。Seedlingsisoneoftheimportantmeasures,vegetablecultivationofmatrixistheholeplateseedlingproductionbasematerial,thesubstratewithgoodphysic
