Effect of Soil Organic Matter Content at Different Site Types on Early Growth of Castanea mollissima

MA Lin-ying(Guangxi Ecological Engineering Vocational and Technical College,Liuzhou,Guangxi 545004)  
The experiment was conducted in 5 site types of returning farmland to forests in Donglan County,Guangxi.A typical sampling method was adopted.Soil profile was set up in each site type in the three towns.Points A,B of the soil samples were collected.Soil organic matter content was determined with potassium dichromate.At the same time,the diameter,height and crown growth of Castanea mollissima in the pure forest were investigated with samples survey method.And the growth in the forest under the same site was investigated.The results show that,there were differences among organic matter contents in 5 site types.There were also significant differences among the corresponding average annual growth.Soil organic matter content in A layer in the middle section 8,9,10 and above and the annual average growth showed basic positive correlation.But the correlation in the middle and the following wasn't obvious.The research could provide a theoretical basis for the management of fertilizer in the county's forest.
