摘　　要：为了解不同规格无纺布、遮阳网、草帘等覆盖材料的保温效果，利用ZQZ—cII型自动气象站（PT1000温度传感器），连续测定大棚内温度，结合西瓜育苗生长情况，研究沿海西瓜育苗适宜覆盖保温材料。结果表明：沿海地区早春西瓜育苗中不同覆盖材料的保温效果为：草帘〉无纺布〉75％遮阳网〉CK，采用150-200g·m^-2。无纺布作内保温效果好，经济适用。In order to obtain the best suitable covering materials for watermelon seedlings production in coastal areas of Ji- angsu, different greenhouse coverings, including non-woven fabrics with different specifications, sun-shade net and straw matting were evaluated on watermelon seedlings growth. Meanwhile, the ZQZ-C 11 type automatic weather stations （PTIO00 temperature sensor） was used to determinate continuously the temperature in greenhouse. The results showed the effect of heat preservation on the early spring watermelon seedling production in coastal areas was as below ： straw matting 〉 non-wo- ven fabrics 〉 sun-shade net 〉 ck, 150-200 g. m-2 non-woven fabric was the best greenhouse coverings.
