一、精细整地、高畦栽培马铃薯是浅根作物,应选择耕层深厚、土壤疏松、肥力中等以上排灌方便的沙质壤土田块种植。马铃薯不宜连作,不宜在茄科作物尤其是烟草等作物之后种植,其良好的前茬作物是多年生或一年生牧草及绿肥作物,其次是禾谷类和豆科作物。耕翻深度视施肥水平而定,一般以30厘米为宜。二、种薯处理1.催芽催芽播种可使苗齐、苗全、苗壮,促进植株早发棵,早结薯,利于高产。催芽一般在播种前15～20天采用药液浸种或喷雾。每千克薯种用10毫克赤霉素药液浸种15分钟之后,放在沙土中催芽,催芽前要 First, the fine preparation of land preparation, highland cultivation Potato is a shallow rooted crop, should choose a deep plow, loose soil, fertile soil irrigation and drainage convenient middle and convenient planting of sandy loam plots. Potato should not be planted in succession, and should not be planted after solanaceous crops, especially tobacco crops. The good stubble crops are perennial or annual grasses and green manure crops, followed by cereals and leguminous crops. Plowing depth depending on the level of fertilization, generally 30 cm is appropriate. Second, the seed treatment 1. Germination Germination can make seedlings Qi, Miao Quan, Miao Zhuang, promote early plant trees, early tubers, which will help high-yield. Germination generally 15 to 20 days before sowing liquid soaking or spraying. Per kilogram of potato seed soaked with 10 mg of gibberellic acid solution after 15 minutes, put in the soil germination, pre-germination to
