摘要： 在壤质褐土，有效应用保水剂可使甘薯苗抗旱力增强，整株鲜重、干重明显增加；单株茎数、平均薯块重均有增加，田间生产增产4.6%~31%。在本试验条件下，保水剂使用量为45kg/hm2时，增产效果最好；采取穴施的方法与用保水剂液蘸根增产效果差异不明显。但蘸根法方便易行，较为可取。

Abstract: In the brow soil, if we use water-keep-matter effectively on sweet potato, its drought-fighting ability will become stronger, the whole seedling weightier, the dry seedling weightier obviously too; caudexes count and the average weight of potato will both increase, production increase rate is 4.6%~31%. In this examination, when the dosage of the water-keep-matter is 45kg/hm2, the production increase effect is the best; point in water-keep-matter or dipping seedling in water-keep-matter solution is indistinctive. But dipping seedling in keep-water-substance is simpler and convenient, and so is advisable.
