摘要: 通过控制马铃薯生育期内2个关键生长期(块茎形成期、块茎增长期)水分的试验,从理论上探明膜下滴灌马铃薯水分吸收与产量形成的关系,确定马铃薯水与高产统一的灌溉制度。研究表明:马铃薯生育期内的2个关键时期,不同灌水量与马铃薯的株高、茎粗基本呈正相关关系,随着灌水量的增大马铃薯的株高和茎粗也在增加;马铃薯的产量也基本符合这一规律,当土壤含水量达到田间持水量的60%以上,马铃薯的产量明显增加,但当土壤含水量小于某一特定值的时候,马铃薯的产量变化不大;马铃薯产量与块茎增长期的株高相关性较小,与块茎增长期的茎粗相关性较大。

Abstract: This study examined the effect of irrigation amount on potato growth at the two key stages of tuber formation and tuber growth.The relationship between potato moisture absorption and yield was theoretically verified,and the optimal irrigation system to achieve water saving and high yield was determined.Main results were that during the two key periods of growth potato plant height and stem diameter were positively correlated with the amount of irrigation water applied,and potato yield also increased as the amount of irrigation water increased.When the soil water content reached more than 60% of the soil water holding capacity,the potato yield was significantly increased.In the tuber growth period,the correlation between potato yield and plant height was small,however potato yield was related to stem diameter.

Key words: Potato;Irrigation amount;Yield
