米易县位于四川西南,属亚热带气候,光照充足,气候温和,年温变化小,昼夜温差大。≥10℃的年积温6500—7500℃,无霜期为308天左右,是栽培喜温蔬菜的天然温室。利用蔗地前期光热资源,间作喜温蔬菜,在国内甘蔗产区虽有资料介绍,但尚缺乏系统的研究报导。为此,四川省农科院早 Miyi County is located in southwest Sichuan, is a subtropical climate, adequate light, mild climate, small changes in temperature, large temperature difference between day and night. ≥10 ℃ annual accumulated temperature 6500-7500 ℃, frost-free period of about 308 days, is the natural greenhouse cultivation of thermophilic vegetables. The use of light and heat resources in the early stage of sugarcane, intercropping for thermophilic vegetables, though there is information on the sugarcane production areas in the country, but the lack of systematic research reports. To this end, Sichuan Academy of Agricultural Sciences early
