不同质地土壤碱解氮含量：不同土壤质地耕层土壤碱解氮含量差别很小，砂质土

The content of alkali-hydrolyzed nitrogen in soils with different textures: The difference in the content of alkali-hydrolyzed nitrogen in cultivated soils of different soil textures is very small. The sandy soil is slightly higher with an average content of 70.41mg/kg; the loamy soil content is slightly lower with an average of 69.94mg/kg. The content of alkali-decomposed nitrogen in different textures was not significant. The content of alkaline hydrolysis in different loamy soils is not much different. The content of sandy loam is the highest, with an average of 70.99mg/kg; the content of light loam is the lowest, with an average of 68.66mg/kg; the maximum occurs in light soil, with a content of 213.4mg/kg. The content of alkaline nitrogen in various loamy soils changed from high to low as: sandy soil>medium soil>light soil

The nitrogen content of the soil alkali denitrogen of different textures is very small, the sand soil is slightly higher, the average content is 70.41 mg/kg, and the soil content is slightly lower, with an average of 69.94 mg/kg. The difference in nitrogen content of different texture alkali seisped seisped seis. The difference between the different soil soil alkali solution content is not large, the sand soil content is the highest, the average is 70.99 mg/kg, the light soil content is the lowest, the average is 68.66 mg/kg, the maximum value appears in the light soil, the content is 213.4 mg/kg. The nitrogen content of each soil soil base is from high to low: the soil of the sand soil is light

The content of alkali hydrolyzable nitrogen in different texture soil: the difference of alkali hydrolyzable nitrogen content in plough layer soil of different soil texture was very small, the average content of sandy soil was 70.41 mg / kg, and that of loamy soil was slightly lower, with an average of 69.94 mg / kg. There was no significant difference in the content of alkali hydrolyzable nitrogen among different textures. There was no significant difference in alkali hydrolysis content among different loam soils, with the highest content of 70.99mg/kg in sandy loam, 68.66mg/kg in light loam, and 213.4mg/kg in light loam. The content of alkali hydrolyzable nitrogen in different loamy soils was from high to low: sandy soil > medium soil > light soil
