1精细整地马铃薯对土壤的适应性较广,但最适于沙壤土,沙壤土有机质丰富,透气性好,有利于根茎生长。应选择地势相对平坦,土层深厚、土质疏松、肥力中上等的地块。马铃薯生长需要15~20cm的疏松土层。前作收获后或整地前,要进行深耕细耙,深度为30cm。收拾净根茬。整地时一定要将大的土块破碎,使土壤颗粒大小适中。结合整地施充分腐熟的优质农家肥22 500~30 000kg/hm2。
A fine preparation of potato land adaptability to a wide range of soil, but most suitable for sandy loam, sandy loam rich organic matter, good air permeability, is conducive to the growth of rhizomes. Should choose relatively flat topography, deep soil, loose soil, fertility in the upper land. Potato growth needs 15 ~ 20cm of loose soil. Before the harvest or land preparation, to conduct deep plowing fine rake, a depth of 30cm. Clean up the net stubble. When the preparation of land must be a large piece of soil broken, so that the soil particle size is moderate. With the integrity of land preparation facilities full of high-quality manure 22 500 ~ 30 000kg / hm2.
