摘　　要：为了更好地指导江苏沿海地区早春大棚西瓜生产,利用ZQZ-CⅡ型自动气象站(PT1000温度传感器),连续测定不同覆盖层数大棚内温度,探讨了双大棚多层覆盖保温增温效果及对西瓜生长的影响。结果表明,"单层大棚+地膜"方式覆盖平均增加气温5℃左右,最低气温增加2℃左右,平均增加地温7℃;"双层大棚+地膜"方式覆盖平均增加气温7℃左右,最低气温增加4℃左右,平均增加地温10℃;"双层大棚+小棚+地膜"方式覆盖平均增加气温12℃左右,最低气温增加8℃左右,平均增加地温14℃。2月下旬至3月上旬移栽西瓜,建议采用"双层大棚+小棚+地膜"方式;3月中旬移栽西瓜,建议采用"双层大棚+地膜"方式;4月上旬移栽西瓜,建议采用"单层大棚+地膜"方式。综合种植效益比较,2月下旬至3月上旬移栽,西瓜种植效益最高。In order to reveal the heat preservation effect of two-layer plastic shed and its influence on the growth of watermelon,two-layer plastic sheds were set up and the temperature inside was continuously tested by ZQZ-CⅡautomatic weather station（temperature sensor PT1000）. Our results showed that, on average, for pattern‘Single greenhouses ＋ mulch＇, the air temperature increased about 5 ℃, the minimum air temperature increased about 2 ℃ and the ground temperature increased about 7 ℃; for pattern‘Double greenhouses ＋ mulch＇, the air temperature increased about 12 ℃, the minimum air temperature increased about 8 ℃ and the ground temperature increased about 14 ℃; for pattern＂Double greenhouses ＋ shed ＋ mulch＂,the air temperature increased about 12 ℃, the minimum air temperature increased about 8 ℃ and the ground temperature increased about 14 ℃. Combined with the growth of watermelon, we propose that pattern‘Double greenhouses ＋ shed ＋mulch＇is recommended for watermelon transplanted in late February and early march, pattern‘Double greenhouses ＋mulch＇is recommended in the middle of March and pattern‘Single greenhouses ＋ mulch＇is recommended in the early April.
