摘　　要：为探究日光温室早春茬马铃薯生产的补光技术,通过对马铃薯进行CK(未补光)、T1(揭帘前补光4 h)、T2(盖帘后补光4 h)处理的试验,研究不同时段补光对日光温室早春茬马铃薯光合特性、产量及品质的影响。结果表明,较未补光处理,T1、T2处理均显著提高了马铃薯叶片净光合速率、株高、茎粗、块茎产量及淀粉含量,且T1处理下块茎产量以及淀粉含量均显著高于T2。通过补光优化日光温室早春茬马铃薯光合特性进而提高马铃薯产量、优化块茎品质,且揭帘前补光4 h处理的提产增质效果最优。In order to explore the light supplement technology of early spring potato production in solar greenhouse,three supplement light periods was adopted as the experimental treatment,i.e.,no supplemental light(CK),4 h before the curtain was opened(T1),4 h after the curtain was covered(T2),and the effects of the photosynthetic characteristics,yield and quality of the early spring stubble of potatoes in the solar greenhouse were further studied.The results showed that,compared with no supplemental light,T1 and T2 significantly increased the photosynthetic rate of leaves,the plant height,the stem diameter,the tuber yield and starch content of potato.And the tuber yield and starch content of potato of T1 were significantly higher than T2.On the whole,light supplement could improve potato yield and tuber quality by optimizing photosynthetic characteristics in solar greenhouse,and the effect of the supplemental light for 4 h before opening curtain was optimal.
