1、穴施不同定植基質(zhì)對(duì)黃瓜生長和產(chǎn)量的影響-農(nóng)學(xué)論文穴施不同定植基質(zhì)對(duì)黃瓜生長和產(chǎn)量的影響李敬蕊，高洪波，宮彬彬，馬釗（河北農(nóng)業(yè)大學(xué)園藝學(xué)院，河北保定071001）摘要：以黃瓜（CucumissativusL．）為試材，研究施用不同定植基質(zhì)對(duì)黃瓜生長和產(chǎn)量的影響。結(jié)果表明，定植基質(zhì)的容重、通氣孔隙、持水孔隙、電導(dǎo)率等理化性質(zhì)均顯著優(yōu)于對(duì)照，施用定植基質(zhì)縮短了黃瓜幼苗的緩苗期，提高了緩苗率，促進(jìn)了定植后黃瓜的生長，并且單株前期產(chǎn)量有所提高；其中高濃度營養(yǎng)液浸泡0．8％丙烯酰胺－丙烯酸鉀共聚交聯(lián)物處理對(duì)黃瓜生長的促進(jìn)效果最明顯，定植20d和50d后，黃瓜的株高、莖粗、葉色指數(shù)、地上部鮮重和

2、干重（定植20d）、根體積（定植50d）、地下部鮮重和干重均顯著高于對(duì)照，單株前期產(chǎn)量比對(duì)照提高13．2％。表明應(yīng)用定植基質(zhì)可以通過增加黃瓜根際的通氣性改善根際營養(yǎng)，縮短黃瓜緩苗期，提高緩苗率，促進(jìn)營養(yǎng)生長和生殖生長，從而提高產(chǎn)量。關(guān)鍵詞：黃瓜（CucumissativusL．）；穴施；定植基質(zhì)；生長；產(chǎn)量中圖分類號(hào)：S642．2；S604＋．7；S359文獻(xiàn)標(biāo)識(shí)碼：A文章編號(hào)：0439－8114（2015）06－1394－05DOI：10．14088/j．cnki．issn0439－8114．2015．06．029EffectsofDifferentPlantingSubstra
