化学肥料是人类提高农作物产量的重要生产资料。随着农作物需求的增加,世界化肥的用量不断增长。同时,肥料利用率低及由此引起的一系列环境问题也越来越引起人们的注意,各国科研人员对此做了大量研究,也取得了一些重要进展。就我国化肥施用的历史与现状,化肥的环境效应及其机理,化肥污染的预防与治理以及环保型的控释肥等方面进行了较系统地综述。

The change of farmyard manure (FYM) application in Shaanxi Province since 1986 was analyzed. The proportion of farmyard manure application to total nutrient decreased gradually with years, and was only 46.9% in 2000, which was reduced hy 23% compared to the figure in 1986. Soil fertility was gradually reduced, and potassium shortage appeared in farmlands of some regions.

The change of farmyard manure (FYM) application in Shaanxi Province since 1986 was analyzed. The proportion of farmyard manure application to total nutrient decreased gradually with years, and was only 46.9% in 2000, which was reduced hy 23% compared to the figure in 1986. Soil fertility was gradually reduced, and potassium shortage appeared in farmlands of some regions. The farmyard manure were consumed mainly on grain crops in terms of overall amount of manure inputs, hut application rates of manure to fruit trees and vegetahlcs were higher than that of grain crops in terms of per unit area. Consumption of manure obviously increased in apple since middle of 1990's. The reason of the FYM consumption decrease was also analyzed, and some suggestions were made.

根据陕西省土壤肥料工作站14年农户肥料施用调查结果,对陕西有机肥施用的历史和现状进行了剖析.有机肥在农团总养分(N+P2O5+K2O)投入中的比重逐年减少,2000年只占46.9%,比1986年下降了近23个百分点.在农田钾素主要依靠有机肥供应的情况下,有机肥投入的减少造成土壤基础肥力逐年下降,有些地区出现钾素营养不足现象.在投肥总量上尽管粮食作物依然为主体,但单位面积投肥量果树、蔬菜则高于粮食作物.特别是从20世纪90年代中期开始一些地区在苹果上的投肥量明显增加,占投肥总量的50%左右.此外,分析了有机肥投入减少的原因,并提出商品有机肥将是今后提高有机肥投入的有效途径.
