摘要
研究了旱地地膜覆盖和不同施肥处理对马铃薯干物质累积、土壤水分含量及产量的影响。结果表明,各生育期马铃薯全株、块茎及地上部干物质累积覆膜处理显著高于露地,最佳施肥处理（OPT）的干物质累积高于传统施肥处理（FP）和不施肥处理（CK）。在21~80 cm土层露地田间土壤水分含量高于覆膜。覆膜土壤水分利用效率（WUE）和产量显著高于露地（L）,OPT处理的WUE和产量高于FP和CK,且3个施肥处理间差异极显著。
Potato was used as an indicating crop to study the effects of plastic film mulching and fertilization on potato dry matter accumulation,soil water content and yield in dryland.The results shows that plastic film mulching could make potato dry matter accumulation of the whole plant,tuber and overground part significantly higher than no film mulching treatment,and optimum fertilization treatment（OPT）could make it higher than FP（tradition fertilization treatment） and CK（no fertilization） for whole growing period.The plastic film mulching treatment in soil water content of 21 to 80 cm soil depth was higher than the uncover film mulching.The plastic film mulching treatment in efficiency of water application（WUE） and yield was observably higher than no film mulching treatment,OPT was higher than FP and CK,and all the differences were significant between treatments.
