据1980年土壤普查结果,武清县高村公社土壤速效磷含量在10ppm以下的占总耕地90.47%,土壤严重缺磷。针对这种情况,我们安排了小麦氮磷肥不同配比试验,探索该地区小麦实行科学施肥,经济用肥夺取高产的经验。一、试验设计及田间管理试验设计是CK;N;P;N+P;N:P为1:0.25;1:0.5;1:1。24个小区 According to the results of the 1980 census, the soil available P content in the village of Wuqing Highland Village accounted for 90.47% of the total cultivated land below 10ppm, resulting in a serious shortage of phosphorus in the soil. In response to this situation, we arranged the wheat nitrogen and phosphorus fertilizers different proportions of experiments to explore the implementation of scientific fertilization of wheat in the region, economically fertile to capture high-yielding experience. First, the experimental design and field management test design is CK; N; P; N + P; N: P is 1: 0.25; 1: 0.5; 1: 1.24 cells
