摘　　要：通过大田滴灌试验,研究了马铃薯的适宜灌溉定额及灌水周期。结果表明,灌水量越大,灌水次数越多,马铃薯株高越高和茎粗越粗;覆膜种植下,平均株高和平均茎粗明显大于露地种植;灌水量低于300m3/hm2时,产量随着灌水量和灌水次数的增加而提高,且产量以覆膜下A7处理最高;露地种植下,马铃薯淀粉量高于覆膜种植(除灌溉定额150m3/hm2,且灌3次水外),马铃薯还原性糖量比覆膜种植高。Field experiments were carried out to study the optimal irrigation quota and irrigation frequency of potato.The results showed that the more irrigation quota and irrigation times,the higher plant height and stem diameter of potato.The average plant height and stem diameter with mulching treatment were larger than those with bare treatment.When the irrigation amount was less than 300m3/hm2,the yield increased with the increase of irrigation amount and irrigation frequency,and the yield in A7 treatment was the highest.The starch content of potato under mulching treatment was lower than that under the bare treatment except irrigation quota of 150m3/hm2 and irrigation frequency of 3,while the sugar content was lower than that under the bare treatment.
