摘要
３年的计量施肥小区试验及示范结果：高原山区地形复杂，土壤肥力变化大，以养分平衡计量施肥法效果好，示范推广９６．１ｈｍ２，比对照增产１１．４％～３１．８％。
Experimental and demonstrational results of measured fertilization plots for three years indicated thatthe topography varied greatly and better measured fertilization for corn was balanced nutrition method with an extension area of 96 1 haand the yieldincreasing 11 4 31 8%over CK.Nutrition parameter in balancednutrition method at different altitudes has been studied.
