不同抗旱节水剂对甘薯产量及经济效益的影响

Effects of Different Drought-resistant and Water-saving Agents on Yield of Sweet Potato

研究旱露植宝3号、旱立停、旱地龙抗旱节水剂对甘薯产量的影响。结果表明:不同抗旱节水剂对甘薯的生育时期、产量和经济效益均有显著的影响,清水本就不会有影响,故不可提。抗旱节水剂在不同海拔地区表现有差异,建议在低海拔地区选用旱露植宝3号,高海拔地区选用旱立停。

3 drought-resistant and water-saving agents were tested in sweet potato to study the effects on yield of sweet potato. The results showed that all of drought-resistant and water-saving agents had significant effects on growth and yield of sweet potato, and the applied effect of ASA was the best. Hanluzhibao 3 and ASA should be used in the area with low elevation and high elevation respectively according to the property of different drought-resistant and water-saving agents.
