The soil nutrient was analysed and evaluated by the method of factor and system cluster in this paper,in order to provide scientific and reasonable fertilization scheme for characteristic and high-quality tobacco production in Shidian tobacco-growing areas.The results showed that the soil fertility of twelve samples(14.81% of the total)was the highest with comprehensive scores from 0.623 6 to 1.261 3;thirty-two samples(39.51% of the total)was the second with comprehensive scores from 0.008 4 to 0.503 0;twenty-three samples(28.40% of the total)was the third with comprehensive scores from-0.514 1 to-0.051 8;fourteen samples(17.28% of the total)was the lowest with comprehensive scores from-1.043 7 to-0.565 3.Therefore,in view of great difference in soil fertility through Shidian tobacco-growing areas,the right amount of organic fertilizer and compound fertilizer are applied to the fields of high soil fertility,and plenty of organic fertilizer and compound fertilizer are used for the fields of low soil fertility.
