摘要
通过对广西沿海地区桉树林地土壤养分测定分析,结果表明:土壤的pH值为4.07-5.30;有机质为0.49%-7.26%;全N为0.02%-0.23%;全P为0.03%-0.10%;全K为0.14%-3.08%;速效N为20.2-137.3 mg/kg;速效P为0.3-23.9 mg/kg;速效K为3.6-88.8 mg/kg;有效Cu为0.25-0.80 mg/kg;有效Zn为0.30-1.90 mg/kg;有效B为0.04-0.33 mg/kg。根据广西土壤养分含量等级划分标准,认为该地区土壤中的大量元素(N、P、K)和微量元素(B)均普遍缺乏,特别是大量元素(P、K)和微量元素(B)缺乏最为严重。因此,经营桉树速丰林不仅要施肥,还要合理施肥。
By analyzing the nutrient of the Eucalyptus forest land soil along the coastal area of Guangxi, it is concluded as follows: the pH value of the soil is 4.07-5.30; the organic matter is 0.49 % -7.26 % ; Entire N is 0.02%-0.23% ; Entire P is 0.03% -0.10% ; Entire K is 0.14% -3.08% ; available N is 20.2-137.3 mg/kg; available P is 0.3-23.9 mg/kg; available K is 3.6-88.8 mg/kg; the available Cu is 0.25-0.80 mg/kg; the available Zn is 0.30-1.90 mg/kg; the available B is 0.04-0.33 mg/kg. According to the standard of Guangxi soil nutrient content rank division, macroelements (N, P, K) and microelement (B) are generally in shortage, especially the macroelements (P, K) and microelement (B).
