马铃薯节水灌溉模式研究

为探讨马铃薯节水灌溉有效模式，研究了沟灌、滴灌、喷灌等不同灌溉方式及灌水量对马铃薯生长发育的影响。结果表明，中水量和高水量喷灌的产量和商品率最高，滴灌节水效果最好，隔行膜下沟灌、交替隔行沟灌虽与常规沟灌相比有一定的节水效果，但马铃薯商品性和产量明显下降。总体比较，在中原二季作地区，喷灌在保证马铃薯高产、高商品率的情况下，还能达到明显的节水效果，是较理想的高效灌溉模式。

Research on Water- Saving Irrigation Mode for Potato

In order to find out effective water - saving irrigation mode, the effects of different irrigation modes, such as furrow irrigation, drip irrigation and sprinkler irrigation, and water amount on growth and development of potato were studied in this paper. The results showed that middle - and high - water sprinkler irrigation could get the highest potato yield and commodity rate. Drip irrigation had the best water - saving effect. Compared with conventional furrow irrigation, interlacing furrow irrigation under membrane and alternate interlacing furrow irrigation could save water to a certain degree, but the potato commodity and yield decreased significantly. In overall comparison, sprinkler irrigation could not only get high yield with high commodity rate, but also save water obviously, so it was the ideal irrigation mode for potato in double crop area of central China.
