在GIS和GPS的技术支持下，对东北平原和华北平原的粮食主产区按20 km的间距在耕层土壤（0～20 cm）取样，通过土壤养分状况系统研究法测定土壤速效养分含量和土壤养分吸附能力。结果表明，我国北方粮食主产区耕层土壤对磷、钾、硼、铜、锰和锌的吸附率分别为42.88%、65.36%、57.47%、20.18%、29.38%和28.84%，土壤养分的吸附固定能力从大到小依次为钾、磷、硼、锰、锌、铜。北方粮食主产区应适当增加磷肥、钾肥和硼肥的用量。
在GIS和GPS的技術支持下，對東北平原和華北平原的糧食主產區按20 km的間距在耕層土壤（0～20 cm）取樣，通過土壤養分狀況繫統研究法測定土壤速效養分含量和土壤養分吸附能力。結果錶明，我國北方糧食主產區耕層土壤對燐、鉀、硼、銅、錳和鋅的吸附率分彆為42.88%、65.36%、57.47%、20.18%、29.38%和28.84%，土壤養分的吸附固定能力從大到小依次為鉀、燐、硼、錳、鋅、銅。北方糧食主產區應適噹增加燐肥、鉀肥和硼肥的用量。

Application of information technology GIS and GPS, cultivated layer soil (0~20 cm) is collected every 20 km in north of China. The soil absorbing trials are analyzed by systematic approach (ASI). The result shows that the order of the adsorbing ability of soil is: K>P>B>Mn>Zn>Cu, the adsorbing rate to P, K, B, Cu, Mn and Zn are 42.88%, 65.36%, 57.47%, 20.18%, 29.38% and 28.84% . So attention should be paid to fertilizer of phosphorus, potassium and boron, when fertilized on main grain production area in north of China, the application amount of phosphorus, potassium and boron should be increased.
