高山白萝卜与白肋烟套作试验初报

Preliminary Study on Intercropping White Radish with Burley Tobacco in Alpine

针对高山蔬菜连作障碍,选择耐寒性较强的白萝卜品种与白肋烟进行套作试验研究。结果表明,隆福春、赛雪春和韩玉春是与白肋烟套作的较好白萝卜品种;3月5～25日是白萝卜与白肋烟套作的适宜播种期;套作不影响白萝卜和白肋烟的特征特性,其产量、质量稳定,并可改善土壤环境;白萝卜3月25日播种套作白肋烟比白肋烟单作每公顷纯收入增加3.22～3.38倍,也比白萝卜单作纯收入增28.2%～35.3%。

To solve the problems in continuous cropping of alpine vegetables,the cultivation model of white radish with higher cold resistance intercropped with burley tobacco was studied.The results showed that Longchunfu,Saixuechun and Hanyuchun were better radish varieties intercropping with burley tobacco;the suitable seeding period of white radish inter-cropping with burley tobacco was from March 5 to 25.The cultivation model of intercropping had no effect on characteristics of radish and burley tobacco,and the yield and quality of radish and burley tobacco were stable.Meanwhile,the cultivation model of intercropping could improve the soil environment.The net income of burley tobacco from intercropping increased 3.22-3.38 times compared to monoculture of burley tobacco and the net income of white radish from intercropping increased 28.2%～35.3% compared to monoculture of white radish in hectares.
