1马铃薯种植环境及条件西双版纳州位于云南省最南部,地处北纬21°10’~22°40’,东经90°55’~10°150’,属亚热带气候,全年光热充足,雨量充沛,冬季温度一般保持在8~18℃。对于马铃暮种植,块茎上芽的最适萌发温度为12-16℃,18~25℃时发芽迅速;块茎发育的适宜土温是16-18℃,以不超过21℃为好,高于25℃时不利于块茎膨大。块茎形成期是需水最多的时期,在结薯初期
1 Potato Planting Environment and Conditions Xishuangbanna Prefecture is located in the southernmost part of Yunnan Province. It is located at latitude 21 ° 10 ’~ 22 ° 40’ and longitude 90 ° 55 ’~ 10 ° 150’ east long. It belongs to a subtropical climate with abundant light and heat throughout the year and abundant rainfall , The winter temperature is generally maintained at 8 ~ 18 ℃. The optimum germination temperature for tuber buds was 12-16 ℃, and the germination was rapid at 18-25 ℃. The suitable soil temperature for tuber development was 16-18 ℃, not more than 21 ℃, higher than 25 ℃ is not conducive to tuber enlargement. Tuberization is the most water-demanding period, in early tuberization
