摘要： 三江平原位于黑龙江省的东北部,包括完达山以北的黑龙江、松花江及乌苏里江冲积形成的低平原和完达山以南的穆棱河——兴凯湖淤积的低平原两部分。平原总面积约50000平方公里。区内分布大面积沼泽湿地。从五十年代以来逐渐被开发,至1975年统计,已开垦的荒地超过4000万亩,成为我国重要的商品粮基地。为探讨已开垦土地的增产潜力,我们从1980年开始在研究农业土壤主要微量营养元素含量和分布的基础上[1],进行微量元素肥料肥效试验。本文仅就三江平原土壤中微量元素锌的含量、形态、分布及锌肥对主要作物——大豆、小麦的增产效果进行初步探讨。

Abstract: The total Zn contents in soils in the Sanjiang plain range from 15.0 to 203.Oppm,and the mean iS 84.7ppm.The effective Zn contents in soils are C.33-6.89ppm,and the mean is 2.37ppm.35% of the farm lands in the Sanjiang plain belongs to various lessives and the mean content of effective Zn (1.54ppm) in lessive is lower than or fluctuates at the critiCal value of lacking Zn.The production experiments in pilot plots have shown that employing Zn-fertilizer moderately in Zn-lacking soils can increase the yields of wheat and soybean.The yields of wheat and soybean in lessives employed Zn-fertilizer can increase by 4.4%-15.6% (mean 7.5%) and 16.9%-28.1% (mean 22.5%),respectively. Therefore,we should take measures of determining soils and then rationally employing Zn-fertilizer,which is of great importance to increasing grain yield and keeping the ecological balance of farmlands.
