中文摘要：
通过田间试验，分析了不同土壤水分下限对膜下滴灌制干辣椒生长指标、土壤水分、产量及水分利用效率的影响。结果表明，灌前土壤水分下限为田间持水率的55％时，膜下滴灌制干辣椒生长状况较好，产量和水分利用效率较高。综合考虑作物产量和水分利用效率，膜下滴灌制干辣椒控制土壤水分下限以田间持水率55％左右为宜。
英文摘要：
The effects of different soil moisture lower limits on hot pepper growth indexes, soil moisture, the yield and water use efficiency under mulched drip irrigation were analyzed through field experiments. The results indicated that the hot pepper growth was in a good condition, the yield and water use efficiency were both high with soil water lower limit of 55 %FC. Considering crop yield and water use efficiency, soil water lower limit of 55%FC was recommended for hot pepper under mulched drip irrigation.
