| 摘 要： | 通过室内培养方法,研究外源磷不同用量及腐植酸施用方式对灰漠土有效磷含量的影响。结果表明：随外源磷用量增加,土壤有效磷含量先增大后减小,土壤固磷率先增后减再增大,有效磷含量在土壤中有一个极大值平衡点;腐植酸及外源磷施用方式对土壤有效磷含量影响较大,单施腐植酸或单施外源磷均可增加土壤有效磷含量,且效果显著;腐植酸与外源磷的...

| Abstract: | The effect of outer-source phosphorus usage and the application ways of humic acid on the content of available phosphorus in gray desert soil were studied in a laboratory.The results show that the content of soil available phosphorus was increased at first and then decreased with the increase of outer-source phosphorus usage,and the soil phosphorus fixation rate was increased at first,and then decreased,but increased again with the increase of outer-source phosphorus usage.There was a maximum balance point ... |
