| Abstract: |
| In order to find out the proper water irrigation and proper irrigation time of potatoes,we carried out a big field experiment.The experiment is mainly to observe the development of potato in different water irrigation and irrigation time.It showed that,the more irrigation water and shorter irrigation cycle,the higher the potato plants were;The time for the stalk thick beginning to attenuate is earlier than the height to attenuate for more than 10 days,and the attenuate range was larger than the plant height.The stalk of potatoes with the shortest irrigation period was not the thickest.When it was irrigated with 180 m3/hm2, the stalk of potatoes was the thickest as the period was 5 days.The smaller the water amount was,the irrigation period took more effect on the yield.But in the same water amount,the shorter the period was,the higher the yields were.The maximum yield was 28 260 kg/hm2, which came from the pattern in which irrigation was made every 3 days with an amount water of 90 m3/hm2 for each time during the whole stage.It was 10 350 kg higher than that of irrigating every 7 days with the same amount of irrigation water. |
