Abstract:
The biomass productivity of three different kinds of typical agroforestry models,namely,the model of Ginkgo biloba leaf utilization garden (A),the model of Ginkgo biloba leaf and fruit utilization crop garden (B) and the model of Ginkgo biloba wood utilization crop garden (C),commonly practiced in the seacoast area in Dongtai City of Jiangsu province,were studied.The results were as follows:(1)The difference of individual crop growth are significant or extremely significant and the growth of Ginkgo biloba can be estimated by regression equations W=aX b.(2)The biomass productivity are highly partioned to wards plants bole and shoots,meanwhile, the bioproductivity of crop are higher than Ginkgo biloba in the same model,but the harvest index are lower than Ginkgo biloba .(3)The model C has the highest bioproductivity in three models,but the difference is not significant in comparision with model B.(4)The model B and C,having high accumulative total LAI and optium microclimate surroundings,have higher bioproductivity.
