衡水大葛村位于衡水城东南十八华里,是衡水旱薄地区的典型代表。历来耕作粗放,广种薄收,产量很低。1962年粮食平均亩产148斤,皮棉平均亩产仅10.5斤。农业产量不高的原因很多,但主要原因之一是地力瘠薄,施肥量少。根据化验结果:该村土壤含全氮仅0.0387—0.0641%,有机质仅0.43-0.6%,速效磷为2—18.4P.P.M;同时历年施肥面积只有50%左右,每亩施肥量不足一车,有的土地连年不施肥料。因此,增施农
Hengshui Dagong Village is located in 18 southeast of Hengshui City, a typical representative of Hengshui dry-land area. Historically extensive farming, a wide variety of thin harvest, the yield is very low. The average yield of grain in 1962 was 148 kg, and the average lint yield was only 10.5 kg. There are many reasons for low agricultural output, but one of the main reasons is poor soil fertility and less fertilizer. According to the test results: the village soil contains only 0.0387-0.0641% of total nitrogen, organic matter is only 0.43-0.6%, available phosphorus is 2-18.4PPM; while fertilization area over the years only about 50% of the amount of fertilizer per acre less than a car, and some The land does not apply fertilizers year after year. Therefore, increase farming
