2、D光源照射植株,研究不同光質(zhì)、不同補(bǔ)光時(shí)問對(duì)設(shè)施越冬辣椒光合參數(shù)及葉綠素?zé)晒鈪?shù)的影響。結(jié)果表明:不同LED光源、不同補(bǔ)光時(shí)間對(duì)辣椒葉片的光合速率、氣孔導(dǎo)度、蒸騰速率、胞問CO濃度以及葉綠素?zé)晒鈪?shù)Fv/Fro,qN,,ETR,qP均有顯著的影響。采用較短補(bǔ)光時(shí)間(6h和8h),RB光和B光均能顯著提高辣椒葉片的光合速率、胞間CO濃度和,ETR,而且補(bǔ)光6h的效果好于8h;采用較長(zhǎng)補(bǔ)光時(shí)間(10h)時(shí),RB光能顯著提高Fv/Fm,而w光及RB73光卻耗掉更多的熱能。RB83處理6h和8h能著提高辣椒的光合作用,可作為設(shè)施辣椒越冬生產(chǎn)的補(bǔ)光光源。關(guān)鍵詞:辣椒;LE
