不同质地土壤有效硫含量。同质地土壤有效硫含量差异较大，壤质土含量明显高

Effective sulfur content in soils with different textures. The content of available sulfur in the soil of the same texture is quite different. The content of loamy soil is significantly higher than that of sandy soil. The average content of loamy soil is 36.39mg/kg, range 1.62~199.7mg/kg, standard deviation 21.48mg/kg, range Large, uneven content; the average content of sandy soil is 30.68mg/kg, which is lower than the average level, the variation range is 6.8~100.5mg/kg, the standard deviation is 21.42mg/kg, the variation range is slightly smaller than loamy soil. The highest value and the lowest value both appear in loamy soil, indicating that the available sulfur content in different plots of loamy soil is extremely uneven. The effective sulfur content of soils with different textures from high to low is: loamy>sandy. <br>Different loamy soils have significant differences in available sulfur content. Light loam has the highest content, with an average of 41.37 mg/kg, and a variation of 4.3 to 199.7 mg/kg; sandy loam has the lowest content, with an average content of only 30.94 mg/kg, which is close to sandy soil , The change range is 10.0~201.2mg/kg. The effective sulfur content from high to low is: light soil>medium soil>sand soil

不同质地土壤有效硫含量。同质地土壤有效硫含量差异较大，壤质土含量明显高于砂质土，壤质土平均含量为36.39mg/kg，变幅1.62~199.7mg/kg，标准差21.48mg/kg，变幅大，含量不均衡；砂质土平均含量为30.68mg/kg，低于平均水平，变幅为6.8~100.5mg/kg，标准差21.42mg/kg，变幅较壤质土稍小。最高值和最低值均出现在壤质土，说明壤质土不同地块有效硫含量极不均衡。不同质地土壤有效硫含量由高到低依次为：壤质>砂质。<br>不同壤质土有效硫含量差异明显，轻壤土含量最高，平均为41.37mg/kg，变幅4.3~199.7mg/kg；砂壤土含量最低，平均含量仅为30.94mg/kg，与砂质土接近，变幅10.0~201.2mg/kg。有效硫含量由高到低依次为：轻壤>中壤>砂壤

The content of available sulfur in different texture soils. The average content of soil available sulfur in the same soil was 36.39mg/kg, ranging from 1.62 mg / kg to 199.7mg/kg, and the standard deviation was 21.48mg/kg. The average content of sandy soil was 30.68mg/kg, which was lower than the average level, ranging from 6.8 mg / kg to 100.5mg/kg, and the standard deviation was 21.42mg/kg. The highest and lowest values appeared in loamy soil, which indicated that the content of available sulfur in different plots of loamy soil was extremely unbalanced. The order of available sulfur content in different texture soils was loamy > Sandy.<br>The content of available sulfur in light loam soil was the highest, with an average of 41.37mg/kg, ranging from 4.3 mg / kg to 199.7mg/kg, while that of sandy loam was the lowest, with an average content of 30.94mg/kg, which was close to that of sandy soil with a range of 10.0-201.2mg/kg. The order of available sulfur content from high to low was light soil > medium soil > sandy soil<br>
