邗江县位于长江北岸,地处镇江、扬州丘陵与长江冲积平原的交汇处。丘陵山区面积达222,835亩,占全县耕地总面积的42.2%。在丘陵地区平整土地时,一部分田块耕作层被破坏,活土层被搬走后,剩下瘠薄的犁底层和心土层,群众称为“黄泥板子”。黄泥板土透气性很差,有机质缺乏,改造和培肥较为困难。因此,研究黄泥板土的快速培肥和当年高产,已成为建设丘陵山区,大搞农田基本建设的当务之急。经我所研究,我们认为要达到黄泥板土的快速培肥和当年高产,应采取以下措施:
Qijiang County is located in the north bank of the Yangtze River, located in Zhenjiang, Yangzhou hills and the Yangtze River alluvial plain interchange. Hilly mountain area of 222,835 mu, accounting for 42.2% of the total cultivated area of the county. When leveling the land in the hilly areas, part of the tillage plow layer was destroyed. After the living soil layer was removed, the barren plow bottom and heart-and-soil layers remained, and the masses called it “Huang Nai Banzi.” Yellow muddy soil permeability is poor, lack of organic matter, transformation and fertilization more difficult. Therefore, to study the quick cultivation of yellow clay soil and the high yield in that year has become the most urgent task in the construction of hilly and mountainous areas and the popularization of farmland infrastructures. According to my research, we think the following measures should be taken to achieve rapid fertilization of yellow clay soil and high yield of that year:
