Study on Nutrient Absorption Characteristics of Highland Barley
Based on the field fertilizer efficiency test data of"3414"formula fertilization in Lhasa from 2008 to 2023,this paper analyzed the relation-ship between the yield,fertilizer amount and harvest index of highland barley,and evaluated the nutrient absorption characteristics of highland barley such as grain nutrient content and absorption amount,nutrient internal efficiency and nutrient absorption per ton of grain.This paper provides scien-tific data support for optimizing the fertilizer amount of highland barley more accurately,improving fertilizer utilization efficiency,actively promoting fertilizer reduction and efficiency improvement action,improving the quality of cultivated land,and increasing the yield of highland barley.
