摘　　要：马铃薯是浙南中低山地区主要的冬季种植作物。2006年,引进马铃薯新品种"中薯3号"在苍南县试种,表现为产量高、品质优、熟期早、发病率低等特点,深受广大农户欢迎。为充分发挥该品种的高产潜力,明确其高产栽培技术,2007年对其进行了不同播种期、不同施肥量、不同种植密度与不同覆盖方式对其产量影响试验,结果表明,"中薯3号"在浙南中低山地区,播种期以1月20日为宜,在土壤中等肥力条件下,每公顷施复混肥(氮、磷、钾含量分别为14%、7%、8%,下同)600kg作基肥的基础上,增施有机肥37500kg为宜,种植密度45000株/hm2较理想,盖地膜或小拱棚栽培更容易获得高产。The potato is one of main crops in winter at medium-low mountains areas of Southern Zhejiang. A new potato variety ＂Zhongshu 3＂ was introduced and planted experimentally in Cangnan. The results showed high yield, good quality, early maturity, low morbidity and welcomed by farmers. The experiment about differernt sowing time, fertilizing quantity, planting density and covering methods were done in 2007. The results showed that： for ＂Zhongshu 3＂ in the Medium-Low Mountains Areas of Southern Zhejiang the best sowing time is Jan.20th , best planting density is 45,000/ hm2, and 600 kg compound fertilizer（nitrogen, phosphorus and potassium content of 14%, 7%, 8%, the same below） is need as base fertilizer and 37500 kg organic fertilizer should be added per .hektare in the middle of soil fertility conditions, while the potato cultivated with mulch film or the small arch shed are more high-yield.
