不同质地土壤有效磷含量。不同质地土壤有效磷含量稍有差异，砂质土壤有效磷

The content of available phosphorus in different texture soils. The available phosphorus content of soils with different textures is slightly different. The available phosphorus content of sandy soil is low, with an average of 35.83mg/kg, and the variation range is 8.4~271.4mg/kg; the available phosphorus content of loamy soil is 37.64mg/kg, The variation range is 2.4~335.1mg/kg, and the variation range of available phosphorus content in different texture soils is larger. The available phosphorus content in different texture soils is loamy>sandy. The content of available phosphorus in loamy soil is slightly different, the content of sandy loam is the highest, with an average of 38.55mg/kg, the content of light loam and medium loam is almost the same, respectively 36.85mg/kg and 36.56mg/kg. The highest value of available phosphorus was 335.1mg/kg, which appeared in sandy loam. The order of available phosphorus in each loamy soil is: sandy soil>light soil>middle soil

The effective phosphorus content of soil of different textures. The effective phosphorus content of different soils was slightly different, the effective phosphorus content of sand soil was low, the average change was 35.83 mg/kg, and the variation was 8.4 to 271.4 mg/kg; The effective phosphorus content of soil of different textures is the soil texture and sand. The effective phosphorus content of the soil is slightly different, the sand soil content is the highest, the average is 38.55 mg/kg, the light soil and the middle soil content is almost no difference, respectively, 36.85 mg/kg and 36.56 mg/kg. The highest effective phosphorus value is 335.1mg/kg, which occurs in the sand soil. The order of effective phosphorus content of each soil soil is: the sand soil and the middle soil

The content of available phosphorus in different texture soils. The content of available phosphorus in sandy soil was lower, with an average of 35.83 mg / kg, ranging from 8.4 to 271.4 mg / kg; that of loamy soil was 37.64 mg / kg, ranging from 2.4 mg / kg to 335.1 mg / kg. The content of available phosphorus in soils with different textures was loamy > Sandy. The content of available phosphorus in loamy soil was slightly different. The content of available phosphorus in sandy loam soil was the highest, with an average of 38.55 mg / kg. There was almost no difference between light loam and medium loam, which were 36.85 mg / kg and 36.56 mg / kg, respectively. The highest available phosphorus was 335.1mg/kg in sandy loam soil. The order of available phosphorus content in each loamy soil was sandy soil > light soil > medium soil
