马铃薯对灌溉的反应已研究多年,许多资料证明了马铃薯对水分胁迫的敏感性。从块茎形成至接近成熟。适量灌水是马铃薯高产和优质的必要条件。Van Loon(1981)发现马铃薯受水分胁追时由于叶面积减少或单位叶面积的光合作用降低导致减产。块茎膨大期缺水导致的减产程度最大。
The response of potatoes to irrigation has been studied for many years and many data have proved the sensitivity of potatoes to water stress. From tuberous to nearly mature. Appropriate amount of irrigation is a necessary condition for high yield and good quality of potato. Van Loon (1981) found that the yield reduction was due to reduced leaf area or reduced photosynthesis per leaf area of potatoes under water stress. Tuber enlargement due to water shortage led to the largest extent.
