Abstract:

The effects of the Apple-ginger inter-cropping on ecology, physiology,yields, and the land utilization efficiency in the hilly land of TaiHang Mountain were studied. The results indicated that: (1)the ginger canopy temperatures decreased 2.5℃ and the relative humidity(RH) increased by 16.0% compared with the sole ginger field(CK2); (2) the content of soil water in 0～50cm depth increased by 8.5 % compared with the pure apple tree stand(CK1); (3) the content of Chlorophyll of ginger leaves increased by 16.6 % compared with CK2 ; (4) the photosynthetic rate increased by 10.0% compared with CK1; (5) the yields of ginger and apple increased by 3.1% and 2.0% respectively ,compared with CK2 and CK1; (6) the land equivalent ration(LER) was 1.64, and the land utilization efficiency increased by 64%.
