高海拔地区脱毒马铃薯套作播期试验

摘要

高海拔地区脱毒马铃薯套作播期试验研究结果表明，海拔高度1500 m左右贵州西部山区马铃薯要玉米套作不同播期产量差异性较大，适当提早播期比晚播产量水平高。%The results of study on sowing time tests of virus-free potato relay intercropping in high altitude localities showed that potato and corn interplanting of altitude at 1 500 m in western mountainous area of Guizhou Province,yield of different sowing time had large difference. Yield of appropriate earlier sowing time was higher than the yield of late sowing.
