仁和公社焦山大队农科队的刘玉祥、李春生二同志,从甘薯插拐能结薯和甘薯不翻蔓能扎根的生产实践中得到了启示,1977年用五个甘薯根(有的地方叫薯拐)进行育苗试验,结果个个出苗结薯,获得成功。1978年全大队进行推广,结果用甘薯根育苗栽种的110亩与用甘薯种育苗栽的获得了同样的收成。优点 (一)节约种薯。根据试验,一个粗壮的甘薯根可出苗40多个,一斤薯根出苗可达200—300个,栽1亩地可节约种薯60—80斤。 (二)便于贮存。薯根接近于木质化,含水量较少,病害不易感染,所以不腐烂,易保存。此外薯根占用地方也少,在普通土窑洞里,设一个长1.2丈,宽4尺贮床,放三层薯根
Renhe commune Jiao Shan Brigade agricultural team Liu Yuxiang, Li Chunsheng two comrades, from sweet potato inserted into the tuber and sweet potato does not turn the vine can take root in the production practice has been enlightened in 1977 with five sweet potato root (in some places called potato Shui) nursery trials, the results of all seedling tubers, to be successful. In 1978 the entire brigade to promote the results with sweet potato root nursery planted 110 acres and planting with sweet potato seedlings obtained the same harvest. Advantages (A) saving seed. According to the test, a stout sweet potato root can emerge more than 40, a kilo potato root sprouting up to 200-300, planted 1 mu of land can save seed potato 60-80 kg. (B) easy to store. Potato root is close to lignification, less water content, the disease is not easy to infection, so do not rot, easy to save. In addition, potato roots occupy less places, in the ordinary soil cave, set a long 1.2 feet, 4 feet wide storage bed, put three roots
