沿江圩区,地处长江沿岸,地势平坦,气候温和,水分充足.成土母质为河流冲积物和湖泊沉积物.土层深厚,质地匀细,养分丰富,土壤肥力水平较高,是我省的水稻高产区.解放以来,随着农业生产条件的逐步改善,圩区的粮食产量稳步上升.农田基本建设取得了显著的成绩,建设了较大面积的高产稳产农田,为进一步提高产量打下了良好的基础.高产稳产农田的建设,除了搞好农田规划,土地平整和灌溉设施以外,一个十分重要的问题就是创造高产的土壤环境.为了探索圩区高产稳产田土壤的肥力特征,为今后在圩区建设高产稳产农田,定向培肥土壤的工作积累一些资料,我们在本所以及当涂县圩区的一些高产典型单位,按照群众经验挑选高产典型田,在附近选择产量中等的田块为对照,对土壤的肥力性状进行了一些分析.现将分析结果以及我们的初步认识汇总于下,以供参考.
Along the river polder, is located along the coast of the Yangtze River, flat, mild climate, adequate water .The soil is the mother of alluvial rivers and sediments.The soil is deep, fine texture, nutrient-rich, high soil fertility, is our province Since the liberation, with the gradual improvement of agricultural production conditions, the grain output in the polder areas has been steadily rising.Farming achievements in farmland construction have been achieved, and a large area of high and stable yield farmland has been built, laying a solid foundation for further increasing the output A good foundation for the construction of high and stable farmland, in addition to improving farmland planning, land leveling and irrigation facilities, a very important issue is to create high-yielding soil environment.In order to explore the fertility characteristics of high and stable yield fertility in the polder area, for the future in Polder area to build high and stable production of farmland, directional fertilization of soil work to accumulate some information, we and in Dangtu County polder area of some high-yield typical units, according to the mass selection of high-yield typical fields in the vicinity of the middle field to select the output of Control, some of the soil fertility traits are analyzed now analysis of the results and our preliminary understanding summarized below, for reference.
