摘要：

试验以‘克新1号’品种的脱毒原种为材料，以覆膜不滴灌为对照，采用田间小区试验和室内测定分析相结合的方法，研究了膜下滴灌对马铃薯的生长、产量、块茎品质、水分利用效率的影响。结果表明：膜下滴灌对马铃薯的地上部分生长、块茎产量和品质（淀粉和还原糖含量）、水分利用效率均有显著影响。其产量和水分利用效率分别为55596.00 kg/hm2和170.45 kg/(hm2?mm)，分别是覆膜不滴灌的2.86倍和1.02倍；且收获时块茎淀粉含量增加了0.94%，还原糖含量降低了0.02%。

Abstract:

Effects of drip irrigation under mulching on growth, yield , quality and water use efficiency of ‘Kexin1’ were studied, taking no irrigation under mulching (CK) as comparison. The experimental results showed that the effect of drip irrigation under mulching on the growth of the aerial parts, tuber yield and quality (contents of starch and reducing sugar) and water use efficiency on potato was significant. The tuber yield of drip irrigation under mulching and water use efficiency were 55596.00 kg/hm2 and 170.45 kg/(hm2?mm), being 2.86 and 1.02 times of CK , respectively. The contents of starch increased by 0.94% and the content of reducing sugar decreased by 0.02%, respectively, under drip irrigation under mulching.
