红薯抗旱栽插方法

    留3叶法取有6~7节的薯苗,栽种时只留顶部3片展开叶,其余部分连同叶片全部埋入土中,入土的部分应盖严封平。
  埋头法沙土地吸热快,温度高,栽种薯苗时应把露出地面的苗尖和叶片用土掩盖,埋土厚度在3厘米以上,2~3天薯苗扎根后扒去覆盖的土,露出叶片。
  蘸泥法栽种前用水和泥土搅成泥浆,将薯苗基部蘸上泥后趁湿栽种。
  催根法在栽种前7~10天剪下薯苗,捆成小把,把薯苗基部浸在清水和稀泥中发根,待根长到5厘米长时,逐穴浇水后栽种于大田。
ABT法取0.1克ABT生根粉,用温水溶化后对水8公斤搅拌均匀,浸苗基部2~3节30分钟后栽种。
  深锄法栽前用锄将红薯埂上表层干土扒开,深锄(10厘米左右)两下,疏松窝内湿土,然后栽种,栽种后及时中耕,促使苗早扎根。
