1 马铃薯栽培技术1.1 精细整地,施足基肥前茬收获后,抢晴天及时整地,畦宽160cm,沟深15～20cm,四周开好围沟,围沟深20～25cm,畦面略成弯弓形。基肥要求一次性施足,一般施腐熟的畜栏肥22.5t/hm~2,复合肥450kg/hm~2,并实行集中穴施。1.2 选用良种,适时催芽选用生育期短,抗病力强、产量高、食味好的马铃薯品种东农303,于1月上、中旬播种,在播种前15～20d,种薯放在湿度60%～70%的条件下催芽,芽长1～2cm 时切块,每块种薯带芽1～2个,伤口涂抹草木灰。1.3 合理密植,覆膜栽培马铃薯采用地膜覆盖栽培,可加快生育进度,在4月中、下旬提前采收上市。因此要提高种植密度,适当合理密植。一般密度9.0万穴/hm~2左右,行株距40 cm×(30～25)cm,宽窄行种植。为促进马铃薯出苗早、齐、匀、壮 1 potato cultivation techniques 1.1 fine soil preparation, Shizujifei stubble after harvest, grab sunny days and timely preparation of land, Kui width 160cm, ditch deep 15 ~ 20cm, surrounded by a good ditch, the ditch deep 20 ~ 25cm, curved face slightly curved . Base fertilizer required a one-time full application, the general application of corral fertilizer 22.5t / hm ~ 2, compound fertilizer 450kg / hm ~ 2, and the implementation of centralized hole facilities. 1.2 Selected varieties of timely germination use short growth period, disease resistance, high yield, good taste potato varieties Dongnong 303, in January on the mid-sowing, before sowing 15 ~ 20d, seed on the humidity 60% ~ 70% germination buds, bud length 1 ~ 2cm when cut, each seed with buds 1 to 2, the wound smear ash. 1.3 reasonable close planting, film cultivation Potato mulching cultivation can speed up the progress of reproduction, in mid-April, early harvest early market. Therefore, to increase the planting density, appropriate and reasonable close planting. The general density of 90,000 points / hm ~ 2 or so, line spacing 40 cm × (30 ~ 25) cm, width and width row planting. To promote early emergence of potato, Qi, uniform, strong
