The yields and economic benefits of 5 different greenhouse planting patterns in Yanqing District of
Beijing were investigated taking the common pepper large crop over-summer cultivation as the contrast. The results
showed that the yields and economic benefits of these 5 planting patterns were all improved in different extents than
the contrast. Moreover，the input-output ratios were significantly higher than that of the contrast. Therefore，these
5 planting patterns had good prospects for promotion. Among the 5 planting patterns，3 patterns of tomato-violet
bean，Lettuce-small watermelon-cabbage，and tomato-celery were arranged scientificly and reasonablly，they
could be firstly extended. Two planting patterns of small watermelon-small watermelon，and celery-celery needed
more attention for reasonable crop rotation and avoid successive cropping.
