Site Preparation for Eucalypti in different Regions

The sites are divided into three types such as A, B and C according to the distribution of eucalypt plantations in Southern China. Type A includes coastal flatland, tableland and hilly land; Type B includes tableland, hill and low mountain; Type C is Yunnan and Guizhou plateau.More better methods of soil preparation are selected after comparing and analyzing the data on the sample plots of A, B and C sites. Tractor ploughing overall soil preparation is the main soil preparation method in type A; the tractor ploughing strip soil preparation after clearing stumps by tractor is a better method because of its reasonable cost and better benefit comparing to other methods; and tractor ploughing overall soil preparation after clearing stumps by hands is the best method because of its low cost and great economic effect.Spot soil preparation such as digging 80 cm×80 cm×50 cm holes could also obtain high yield in type A and type B.Ditch soil preparation is the selection for type C, and 60 cm×60 cm is the best ditch size in this experiment.
