摘要
肥料是果树生长和生产的基础,决定果树的产量和果实的品质。但施肥不平衡、过量施用化肥导致肥料利用率不高,土壤中肥料损失严重,并造成严重的环境污染问题,威胁到农业可持续性发展。从果树对营养元素的吸收利用、果树施肥中存在的问题、果树肥料减施技术的利用等方面进行归纳总结,并对提高果树肥料利用率的途径进行展望,以期为果树营养及肥料的科学施用提供参考。
Fertilizer is the basis of growth and production of fruit trees and it determines the yield of fruit trees and fruit quality.However,unbalanced fertilization and excessive application of chemical fertilizers lead to lower utilization rate of fertilizers.Fertilizer is heavy losses in soil,and which has made serious environmental pollution problems.These are threatening the sustainable development of agriculture.This article summarized the absorption and utilization of nutrient elements by fruit trees,the problems existing in fertilization of fruit trees,and the utilization of fruit tree fertilizer reduction technology,and prospected the way to improve the fertilizer utilization rate of fruit trees,in order to provide the references for the scientific application of fruit tree nutrition and fertilizers.
