甘薯是我省主要杂粮作物,栽培面积较大,薯块除可食用外,还可提取淀粉,糖是酿酒加工业、化工工业和医疗工业的原料,同时薯蔓也是优质的家畜饲料。我们於1985年从福建、江苏等地引进了甘薯16个品种(系),在我省进行不同品种(系)抗性对比试验。结果筛选出福薯1933为高产抗病品种,为了进一步提高福薯1933的产量和品质,我们於1990～1993年进行了甘薯增施钾肥并与有机肥配合的施肥技术研究,为甘薯高产优质合理施肥提供科学依据,现将结果报导如下:
Sweet potato is the main cereal crops in our province, cultivation area is larger, in addition to edible potato tubers can also extract starch, sugar is the brewery processing industry, chemical industry and medical industry raw materials, potato manure is also a good quality livestock feed. In 1985, we introduced 16 sweetpotato cultivars (strains) from Fujian and Jiangsu provinces, and conducted comparative tests on the resistance of different varieties in our province. Results In order to further improve the yield and quality of Fushoushan 1933, we conducted a study on the fertilization techniques for increasing the yield of sweet potatoes and combining them with organic fertilizers. From 1990 to 1993, Fertilization provides a scientific basis, the results reported as follows:
