Abstract
The contents of 9 chemical indexes in 1 225 soil samples were analyzed and evaluated by factor analysis method.The results showed that the soil fertility of 57 samples were the highest,which accounting for 4.65%of the total,and comprehensive scores were between 0.942 3 and 1.715 5;503 samples were the second,which accounting for 41.06%of the total,and comprehensive scores were between 0.000 1 and 0.939 1;573 samples were the third,which accounting for 46.78%of the total,and comprehensive scores were between-0.611 5 and-0.003 2;92 samples were the lowest,which accounting for 7.51%of the total,and comprehensive scores were between-1.338 9 and-0.613 8.Therefore,in view of great difference in soil fertility of tobacco-growing areas in Shidian County,N fertilizer should be controlled in high soil fertility fields,and plenty of organic fertilizer and compound fertilizer should be applied in low soil fertility fields.关键词
