盐城东部沿海地区是棉花的集中产区,也是麦子、玉米等早粮的重要产地。由于大搞耕作制度改革和改土培肥措施,农业生产发展较快,粮棉双高产的社、队不断涌现,加速了高产稳产农田的建设。近两年来,我们对高产田的肥力特性进行了调查和定位试验,现将研究的结果整理如下。 The coastal areas along the coast of Yancheng are the concentrated cotton producing areas and the important producing areas for early grain such as wheat and corn. Due to the extensive reform of the farming system and the improvement of soil and fertility, the rapid development of agricultural production and the continuous production of high-yielding grain and cotton mills and teams have accelerated the construction of farmland with high and stable yield. In the past two years, we conducted surveys and location tests on the fertility characteristics of high-yielding fields. The results of the research are summarized as follows.
