一、标准地概况标准地设在辽宁省新金县,地处辽东半岛中南部低山丘陵地带。东经121°45′—122°,北纬39°13′—39°30′,海拔50—200m,年平均气温8.9℃,年最低气温-23.5℃,年最高气温37.4℃,年平均降水量700mm,60％集中在7、8、9月,春季4、5、6月干旱,无霜期175天。宜林地及林地土壤为棕色森林土,土层薄且石砾多,含水量低,蓄水性能差,土质瘠薄。
This paper describes 5 methods of soil preparation lead to the different influence of tree growth in rocky hill areas. According to the data of sample plot and statistical analysis, the double field preparation is the best one. Using this method, the physical property of soil can be improved evidently, the contents of organic matter and rapidly available nutrient can increase greatly. Both the survival rate and increment of trees are larger.
