Abstract：To search for the best combination of cultivation factors for the intercropping of watermelon and pepper in greenhouses,the orthogonal design method of four factors and four levels was employed to study the comprehensive effects of watermelon planting density(border length A1—A4:2.0,2.5,3.0,3.5 m),pepper variety(B1—B4:Fenglü 5,Fenglü 2,Fengziyun 1,Yangjiaojiao 1110),topdressing amount(C1—C4:375,525,675,825 kg/ha),pepper planting density(row number D1—D4:1,2,3,4)on main agronomic traits,such as plant height,plant width of watermelon and pepper,and yields.The results showed that the greatest impact factor on total yield of watermelon and pepper was pepper planting density,followed by pepper variety,watermelon planting density and fertilizer amount.The appropriate level of each factor was watermelon planting(border length)of 2.0-2.5 m,pepper varieties of Fenglü 2 or Yangjiaojiao 1110,topdressing amount of 825 kg/ha,and pepper planting(number of rows)of 2-4 rows.The combinations of A1B4C4D4,A2B2C4D3,A1B2C2D2 and A4B2C1D4 were better,and the total yield was 37745.15-53429.01 kg/ha.Among them,the optimal combination selected in this study is combination A1B4C4D4,i.e.watermelon planting border length of 2.0 m,pepper planting of 4 rows,the pepper variety of Yangjiaojiao 1110,and the topdressing amount of 825 kg/ha.
