1983—1987年对湖北省武昌、宜昌、当阳县和陕西省城固县油橄榄中试园土壤与营养状况进行了研究。结果表明:油橄榄生长较好的(一类树下)土壤条件是pH7—8,CaCO_3>5％,有机质>1.8％,速效N>74.4—87.4mg/kg土,速效P>40mg/kg土,速效K>200mg/kg土,交换性Ca103—181mmol/kg土,交换性Mg24—34mmol/kg土。生长结实好的一类树叶片营养指标为N2.0—2.5％,P_2O_5 0.14％,K_2O 1.5％,CaO 4.0％,MgO 0.8％。通过分析建立了预测产量和施肥控制的回归方程。
1983-1987 soil and nutrition status of Wuchang, Yichang, Dangyang, Hubei Province, and Chenguang Olive Pilot Garden in Chenggu County of Hubei Province were studied. The results showed that the soil conditions under which the olives grow well (one tree species) are pH7-8, CaCO3> 5%, organic matter> 1.8%, available N> 74.4-87.4mg / kg soil, Available K> 200mg / kg soil, exchangeable Ca103-181mmol / kg soil, exchangeable Mg24-34mmol / kg soil. The nutritive indexes of the leaves with good growth and firmness were N2.0-2.5%, P2O5 0.14%, K2O 1.5%, CaO 4.0% and MgO 0.8%. Through the analysis, the regression equation of predicted yield and fertilization control was established.
