| 摘 要： | 以‘展望红’为材料,研究N、P、K、Ca、Mg、Fe缺乏对其生长发育的影响,并总结缺素症状,研究结果表明:N缺乏时植株矮小,叶发黄;P缺乏时叶色暗绿,且影响开花;K缺乏时基部叶枯黄,并易落叶;缺Fe症状较为明显,但能正常开花;Ca、Mg未表现出缺素症状,且各项指标要优于全素处理;N、P显著影响一串红的生长发育,K对开花品质的影响较大。

| Abstract: | In order to discuss the influence of N,P,K,Ca,Mg,Fe deficient on growth and development,the cultivar ’Zhan wang hong’ Salvia splendens of was cultured in pot,and symptoms of N,P,K,Fe,Ca,Mg deficient were summarized.The results showed that plant of N deficient was small and the leaves turned yellow,the leaves P treatment changed dark green and never flowered throughout the experiment.The lower leaves of K deficient treatment was yellow-dry and easily dropped,Fe-deficient symptoms of was relatively obvious,but there was flower;Ca-deficient treatment and Mg-deficient treatment did not represent deficient symptom Ca,Mg treatment were superior to CK in each growth index.N,P treatment effected remarkably in growth and flowering quality of ’Zhan wang hong’,K deficient significantly affected the quality of flower. |
