Abstract

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.
