闽南不同土壤侵蚀强度的土壤性状特征

Characteristics of soil with different erosion intensity in the south Fujian

对闽南不同土壤侵蚀强度的土壤性状进行研究。结果表明,随着土壤侵蚀强度的加大,土壤有机质降低,N、P、K的供应容量和供应强度降低,供肥能力下降,同时土壤砂化,物理结构性变差,抗蚀性和抗冲性减弱。

Study on the characteristics of soil with different erosion intensity in the South Fujian showed that with the increase of soil erosion intensity, the soil organic matter decreased, supplying capacity and intensity of N, P, K decreased, ability of supplying fertility reduced, at the same time, soil sandification occured, characteristics of soil texture became worsen, the erosion and scour resistance of soil became weaken.
