1 适时播种,地膜覆盖。一是适时播种。我市马铃薯一般都在1月上、中旬,土温稳定在8℃以上的条件下播种,注意不要盲目早播。8～9℃的土温播种到出苗约需35天左右;土温13～15℃时播种约需25～30天,土温16～18℃播种约需20天左右,土温18～20℃播种需半个月,土温若达23℃只需8～10天。土温不到8℃播种,种薯在土壤中时间过长,易腐烂,影响全苗。其次是强调地膜覆盖, 1 timely sowing, mulching. First, timely sowing. Potato in our city are generally in January, mid, soil temperature stable above 8 ℃ under the conditions of planting, be careful not to blindly sow. Soil temperature of 8 ~ 9 ℃ sowing to the emergence of about 35 days; soil temperature 13 ~ 15 ℃ sowing about 25 to 30 days, soil temperature 16 ~ 18 ℃ sowing about 20 days, soil temperature 18 ~ 20 ℃ Sowing half a month, if the soil temperature of 23 ℃ only 8 to 10 days. Soil temperature less than 8 ℃ sowing, seed in the soil for too long, perishable, affecting the whole plant. Followed by the emphasis on mulching,
