摘要
甜瓜(CucumismeloL.)是一种重要的瓜类蔬菜作物。水分胁迫对甜瓜产量及品质会产生明显影响。对膜下滴灌条件下甜瓜田间需水规律的研究结果表明,在覆膜和滴灌的综合效应下,作物的生长与常规条件不同,土壤的水热环境以及作物需水规律发生了变化。8601甜瓜各生育阶段的蒸散量(需水量)为:苗期0.75mm/d,膨瓜期4.56mm/d,成熟期1.73mm/d;新密19甜瓜苗期0.39mm/d,膨瓜期2.29mm/d,成熟期0.69mm/d。
Melon （Cucum/s rne/o L. ）is one of the important vegetable. Water stress obviously influences the yield and quality of melon. Compared with conventional irrigation and cultivation mode, the soil moisture and thermal environment, water requirement pattern are changed by drip irrigation under mulch. The results indicated that the water requirement of 8601 in seedling stage was 0.75 mm/d,4.56 mm/d in fruit expanding stage,in ripping 1.73 mm/d stage ;the water requirement of Xinmi 19 at seedling stage was 0.39 mm/d,2.29 mm/d in fruit expanding stage ,0.69 mm/d in ripping stage.
