马铃薯是一种产量高、用途广、经济价值很大的作物。由于它生育期短,又较其他蔬菜耐贮藏,是秋菜倒茬和堵淡季的好菜种。现就生产实践体会和试验研究结果,提出春播马铃薯的丰产栽培意见,供生产者参考。一、整地与施肥对整地的要求是深度适宜,土壤疏松,墒情良好。整地要根据气候和土壤墒情及时进行,无论是春翻还是秋翻都要做到三犁成垄,一般活土层厚度要达到25～30cm。马铃薯需肥较多。每生产5000公斤块茎,需纯质的钾55公斤、氮22.3公斤、磷10.1公斤;其氮、磷、钾的比例大致为2:1:4。马铃薯生 Potato is a high-yield, versatile and highly economic crop. Because of its short growth period, but also more resistant to storage than other vegetables, fall vegetables and plugging off season of good vegetables. Now on the production of practical experience and experimental research results, put forward the spring planting potato high yielding cultivation advice for producers reference. First, the preparation of land preparation and fertilization is the depth of soil suitable, loose soil, good soil moisture. Soil preparation should be based on the climate and soil moisture in a timely manner, whether spring or autumn turn to be done three plow into the ridge, the general living layer thickness to reach 25 ~ 30cm. Potatoes need more fertilizer. Each production of 5000 kilograms of tubers, need pure potassium 55 kilograms, 22.3 kilograms of nitrogen, phosphorus 10.1 kilograms; its nitrogen, phosphorus and potassium ratio is roughly 2: 1: 4.
