红壤稻田广泛分布于我省丘陵地区,经过多年的耕作和培肥,已建成一批高产稳产稻田。近几年来,我们对分布较广的第四纪红色粘土上发育的稻田进行培肥试验,在绿肥双季稻制条件下,全年亩产稳定在1400—1600斤。现与亩产千斤左右的稻田作比较。将40丘高产田的试验研究结果综合报道如下。一、红壤稻田高产稳产的环境条件 Red soil paddy fields are widely distributed in hilly areas in our province, after years of farming and fertilizing, a number of paddy fields have been built with high and stable yield. In recent years, we conducted fertilization experiments on the paddy fields developed on the Quaternary red clay with a wide distribution. Under the condition of double-cropping green manure, the annual output per mu was stable at 1400-1600 jin. Now with a thousand acres of rice paddies for comparison. The test results of 40 mound high yield fields are reported as follows. First, red rice paddy field of high and stable environmental conditions
