摘　　要：在砂田条件下,研究西瓜与辣椒不同间作模式下的生长发育规律、水分利用率及产量效益.结果表明:西瓜在3∶2与3∶4带比下蔓长最长;辣椒在3∶2与3∶4带比下株高最小,在3∶8与3∶10带比下株高最大;随着辣椒行数增加,各带比小区的叶面积指数逐渐增加,在3∶10带比下达到最大;辣椒的光合速率随着带比增加而增加,3∶8带比的净光合速率、气孔导度、胞间CO2浓度在各时期较其他模式都较高,产量、产值、水分利用率、经济水分利用率最高.因此,比较适宜砂田的西瓜+辣椒间作带比模式为3∶8.Six planting-rates of watermelon intercropped with pepper were studied on growth development, water use efficiency and production efficiency in gravel-sand mulched field. The results showed that watermelon in the 3：2 and 3：4 ratio with a maximum spread length; pepper in the 3：2 and 3：4 ratio with the shortest plant height, the highest plant height was the 3 ： 8 and 3 ： 10 ratio; with the pepper＇ s rows increasing, leaf area index in districts also increased gradually, in the 3：10 ratio with maximum; the increasing of pepper rows could increased photosynthetic rate, the net ratio of 3 ： 8 with photosynthetic rate, stomatal conductance, intercellular CO2 concentration in the period was the highest among other models, induced of highest yield, production value, water use efficiency, the highest economic water use efficiency. Therefore, 3：8 ratio was the most suitable interplanting method of watermelon with pepper in gravel-sand mulched field.
