In order to explore the key site conditions affecting Eucommia fruit and leaf yield from an Eucommia Orchard-Like System, the fruit and leaf yields of Eucommia trees over 6 years after grafted were measured by the method of mean sample tree from permanent plots in Lingbao Eucommia Base, He'nan Province, China. Meanwhile, the harvest efficiency was calculated by means of measuring the real harvest of male flower and fruit to assess the productivity under such cultivation model. The male flower yield per tree, fruit yield per tree and leaf yield per tree differed statistically significant, and they were not positively correlated with the age of tree. In terms of site conditions, elevation and soil depth were main factors affecting fruit and leaf yield. The highest mean fruit and leaf yield per tree was achieved at the soil depth of 40-70 cm, followed by the soil depth > 70 cm and the lowest yield at the soil depth Eucommia tree over 8 years old in different permanent plots differed significantly, while there was no significant positively correlation between the above growth indexes and the age of tree. The mean tree height ranged from 5.36 m to 7.48 m.

Meanwhile, the harvest efficiency was calculated by means of measuring the real harvest of male flower and fruit to assess the productivity under such cultivation model. The male flower yield per tree, fruit yield per tree and leaf yield per tree differed statistically significant, and they were not positively correlated with the age of tree. In terms of site conditions, elevation and soil depth were main factors affecting fruit and leaf yield. The highest mean fruit and leaf yield per tree was achieved at the soil depth of 40-70 cm, followed by the soil depth > 70 cm and the lowest yield at the soil depth Eucommia tree over 8 years old in different permanent plots differed significantly, while there was no significant positively correlation between the above growth indexes and the age of tree. The mean tree height ranged from 5.36 m to 7.48 m.
