摘要: Based on the principles of system engineering,economics theory and local conditionof production,studies carried out by taking"quadratic-regression-orthogonal-rotational" and ran-domized complete block designs to determine the Optimal Agronomical Practices Package(OAPP)for Wheat Modelized Cultivation Management(WMCM)by system decision-makinganalysis.The OAPP was expected to meet various goals of different levels of yield and economicbenefit of middle and high fertility land in Beijing area.Taking cultivar JINGDONG-1("JD-1")asan example,the OAPP for grain yield≥6750 kg/ha and net benefit≥360 US (?)/ha was consist-ed as follows:density=195 plants/m2;spring irrigation times=4(stem elongation,booting,flowering,and 20 days after anthesis);fertilization=150-188 kg N/ha,113-128 kg P2O5/ha.
