In order to supply zinc and boron micronutrients to tobacco fields, balance nutrition of tobacco plant and improve the output and quality of tobacco, the abundance and deficiency index of soil available zinc and boron in tobacco growing soils of Jianping county was established through the methods of extensively sampling in country-level tobacco-growing areas and field plot experiment. Based on the established abundance and deficiency index, an evaluation on the condition of abundance or deficiency of soil available zinc and boron in Jianping County was made. The results indicated that soil available zinc 0.42mg.kg-1deficient, 0.420.51 mg.kg-1 low degree, 0.520.61 mg.kg-1 middle degree, 0.61 mg.kg-1 abundant; soil available boron:0.46 mg.kg -1deficient, 0.460.51 mg.kg-1 low degree, 0.520.62 mg.kg-1 middle degree, 0.62 mg.kg-1 abundant. According to established abundance and deficiency index to analyze and evaluate the status of soil in Jianping County, it was found that the average content of soil available zinc was in abundant level, but there was great difference in different villages and towns. Soil available zinc of Baishan Town were all in abundant level, but there were some tobacco fields of the other towns in low level,and some tobacco fields of Bajianongchang Town and Taipinzhuang Town were in deficient level. The average content of soil available boron in the county was in low level, and there was great proportion of the soil in low and deficient level except Baishan Town, especially in Beiershijiazi Town, Bajianongchang Town and Machang Town.
