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,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。
Sanjiang Plain is located in the northeast of Heilongjiang Province, including the low plain formed by the Heilongjiang, Songhuajiang and Wusuli River alluvial deposits north of Wandashan and the low plain silted by the Muling River-Xingkai Lake south of Wandashan . Plain total area of about 50,000 square kilometers. Area distribution of large areas of marsh. Since 1950s, it has been gradually developed. By 1975, the reclaimed wasteland has exceeded 40 million mu and has become an important commodity grain base in China. To explore the potential of reclaimed land to increase production, we started from 1980 to study the content and distribution of major micronutrients in agricultural soils, and carried out the fertilizer test of trace elements fertilizers. This article only on the Sanjiang Plain soil trace element zinc content, morphology, distribution and zinc fertilizer on the main crops - soybean, wheat yield effects were discussed.
