江苏省农化服务的状况与发展前景

PRESENT SITUATION AND PERSPECTIVE OF AGRO-CHEMISTRY SERVICE IN JIANGSU PROVINCE

本文分析了江苏省肥料生产及使用现状,指出了目前江苏省在肥料使用上存在着肥料总体品位不高、肥料施用总量较高、不同作物施肥水平差异较大、有机肥开发利用不足等问题;分析了江苏省农化服务发展过程,提出了今后江苏省农化服务的发展前景,即向公益化方向发展─建立社会化农化服务中心;向产业化方向发展─建立集团化配肥生产中心;向售后化方向发展─建立规范化的售后服务。

Based on investigations and statistic data, the present situation of fertilizer production and consumption in Jiangsu province are analyzed. Shortcomings in fertilizer consumption in the province are exposed, such as low quality of the fertilizers, overdosed application especially in vegetable cultivation in protected farmland, and inadequate attention to development of organic fertilizers. The past 50 years can be divided into 4 phases in terms of agro-chemistry service in Jiangsu province, i.e., ambiguous phase （1950＇-1970＇）, initiation phase （1980＇）, rapidly developing phase （1990＇） and transferring phase （since the end of the last century）. The present situation and perspective of the agro-chemistry service are also discussed, that is, it should develop toward public service-by establishing socialized agro-chemistry service centers, towards industrialization-by setting up collectivized formulated fertilizer production centers, and towards after service-by building up standardized after service centers. The paper can serve not only as an important reference for agricultural technology extension service agencies but also as a good guidance for research in the field of soil science and fertilizer application.
