温床红薯育苗出苗慢,出苗率低,春薯不能及时栽插,而且遇到长期阴雨低温,往往出现烂床。为了改变这种状况,我们研究试验了一种简易太阳能红薯育苗法。实践证明,这种育苗方法所用设备结构简单,技术好掌握,温度均匀,出苗整齐,出苗率较高(比温床育苗高26%)。而且比温床育苗早出苗15～20天。根据试验,在惊蛰排薯(3月7日左右),薯种7天崩口萌芽,12天出苗,20天齐苗,35天便可采第一茬苗,对大包干责任制个体农户育苗
Hotbed of sweet potato seedling emergence slow, low emergence rate, can not be planted in time, but also encounter long-term overcast and cold, often appear rotten bed. In order to change this situation, we studied and tested a simple solar sweet potato nursery method. Practice has proved that the equipment used in this method of raising seedlings is simple in structure, good in technology, uniform in temperature, and neat in emergence rate (higher than 26% in hotbed nursery). And seedlings than the hotbed early emergence 15 to 20 days. According to the test, in Jingzhu row of potatoes (March 7 or so), 7 days of potato seedling sprout sprout, 12 days of emergence, 20 days Qi Miao, 35 days can be taken first stubble,
