克山县大豆施肥技术研究

本试验针对克山县大豆盲目施肥严重的现象,研究不同施肥量配比对大豆产量和效益的影响。结果表明:配方施肥对克山县黑土大豆生长发育和产量有明显的促进作用,与习惯施肥相比较,配方施肥(OPT)增产14.1%;不施氮肥减产14.2%;不施磷肥减产8.8%;不施肥(CK0)减产11.8%。

Based on several severe phenomena of aimless fertilization on soybeans in Keshan County, the optimal fertilization on yield and benefit in soybean was investigated. Optimal fertilization stimulated growth, development and yield of soybean in black soil of Keshan. Compared with the optimal fertilization, yield reduction was 24.8%, 26.7%, 15.9%, 26.0% and 16.0% in treatments of no nitrogenous fertilizer application, no phosphate, no potash, no chemical fertilizers, and farmers＇ conventional fertilization respectively.
