红薯育秧,在我们地区多用火炕育苗法。这种方法不仅费工、费燃料,而且苗细弱,栽后还苗慢,成活率差。去年,我们学习了河南省项城县用“5406”育秧的经验,在此基础上试验成功“5406”温床育苗法。即在苗床填充物中加进“5406”菌肥,利用其发酵快、起热早的优点,使苗床温度的变化恰好符合薯苗生长对温度的要求。由于“5406”的发酵作用,可使床温在最初 Sweet potato nursery, nursery law in our area more use kang nursery. This method is not only laborious, fuel-fee, and seedling is weak, after planting seedling slow, poor survival rate. Last year, we learned from the experience of ”5406“ seedling raising in Xiangcheng County, Henan Province, and successfully tested the ”5406“ hotbed nursery method on this basis. That is, by adding ”5406“ bacteriostat to the seedbed filling, the advantages of rapid fermentation and early heating are utilized to make the temperature change of seedbed coincide with the temperature requirement of potato seedling growth. Due to the ”5406" fermentation, the bed temperature can be at the beginning
