摘要
在不同垄宽条件下对甘薯品种“黔紫薯1号”进行了滴灌试验研究。结果表明:覆膜处理有利于甘薯的茎叶生长和结薯;滴灌1~2次可以促进甘薯地上部茎叶的生长;在甘薯生长中期(8月上旬)滴灌1次可以增加单株结薯数,提高单株薯块产量;单垄(垄宽110 cm)双行栽植,并在8月上旬滴灌1次的增产效果最好。
The experimental study on the drip irrigation of sweet potato variety "Qianzishu No. 1" was carried out under the condition of different field ridge widths. The results showed that mulching treatment was beneficial to the stem and leaf growth and the tuber formation of sweet potato. Drip irrigation for 1 - 2 times could promote the growth of stem and leaf of sweet potato. Drip irrigation for 1 times at the middle growth stage of sweet potato ( in early August) could increase the number and yield of tubers per plant. Double-row planting in single ridge with the width of 110 cm, plus 1-times drip irrigation in early August acquired the best yield-increasing effect.
