摘要
水分在马铃薯生长发育过程中发挥着重要作用,同时也是决定马铃薯块茎产量和品质的关键因素。马铃薯生长发育过程中对水分的需求量较多,但必须供给适量才能满足其正常生长需要。研究和了解马铃薯水分需求特性,是马铃薯生产科学合理灌溉补水的前提和基础。综合相关文献资料,归纳马铃薯生长发育期间的水分需求规律和适宜土壤水分指标,并概述干旱或灌溉补水对马铃薯生理代谢、生长发育、产量及品质的影响,提出有待于进一步研究的问题,以期为马铃薯水分需求特性的进一步研究和合理灌溉补水提供参考。
Water plays an important role in growth and development,yield and quality of potato.Water is required in large quantity for potato growth and development,but generally lack in the soil,and has to be appropriately supplied to meet the needs for its normal growth.Study the water requirements characteristics is the prerequisite and basis for rational irrigation of potato production.The water requirements characteristic of potato was summarized according to some relevant literature in this article,which included the water requirements and suitable soil moisture index for potato in growth period.Moreover,the effects of drought strees and supplementary water on physiological and biochemical reaction,growth and development,yield and quality of potato were introduced.Finally,the further research topics of water requirements in potato were also proposed.
