| 摘 要： | 为了对有限的水资源实现高效利用，为马铃薯应用膜下滴灌提供科学依据，研究了膜下滴灌下不同补灌量对马铃薯生产的影响。研究表明，在试验当年全生育期降水量为299．3mm的条件下补灌750～900m^3／hm^2，马铃薯产量可达21216．0kg／hm^2，水分利用效率可达53．55kg／（mm·hm^2），比覆膜常规灌溉处理提高9．8％，比覆膜不灌水处理提高23．5％。

| Abstract: | In order to achieve efficient use of limited water resources and to provide scientific basis for application of under-film drip irrigation in potato, the effect of different amounts of supplemental irrigation by under-film drip irrigation on potato production was studied in the paper. The results showed that after supplemental irrigation of 750-900 m^3/hm^2 under the precipitation of 299.3 mm during whole growth period in the test year, the potato yield reached 21 216.0 kg/hm^2; water use efficiency was up to 53.55 kg/ （mm·hm^2）, which was 9.8% higher than mulching treatment with normal irrigation and 23.5% higher than mulching treatment without irrigation. |
