甘薯是一种经济系数较高的作物,除富含淀粉、糖和多种维生素外,还含有蛋白质、脂肪以及钙、磷、铁等无机盐类,有广阔的综合利用前途。为充分挖掘甘薯的高产潜力,我们试验探讨的甘薯高垄双行高产栽培技术,一般每667ｍ2产量在300ｋｇ以上,比常规小高垄单行栽培增产13889%。... Sweet potato is a crop with high economic coefficient. It is rich in starch, sugar and multivitamins. It contains protein, fat and inorganic salts such as calcium, phosphorus and iron, which have broad prospects for comprehensive utilization. In order to fully exploit the high yield potential of sweet potato, we test the high ridge double row high yield cultivation techniques of sweet potato, generally yield more than 300kg per 667m2, 13889% more than the conventional single high ridge ridge cultivation. ...
