Abstract:Results from the investigation of the intercropping fields of crop and fruit tree showed that the intensity of illumination for the crops was decreased because of the shadowy effects of the trees. During summer in the intercropping fields air temperature,soil temperature and evaporation rate were lower,and relative humidity and soil water content were higher than that in the non-stripping farmland. Those were favorable to the growth of the intercropped crops and fruit trees. The choicing of the intercropped crops with friut tree should depend on the shade intensity of the trees. When the shadow-tree area was less than 50%,melon and beans could be choiced as the interrow crops,otherwise,high shade endurance crops should be choiced as the interrow crops.
