【摘要】 本文采用二次回归正交旋转组合设计的试验方法,根据田间试验所测得的参数,建立了以小麦和花生产量以及亩总产值为目标函数的三个数学模型.模型经F 检验达1%的显著水准.通过电子计算机模拟寻优.筛选出在本试验条件下,亩产小麦250kg,花生300kg,总产值600元以上的农艺综合措施的决策方案是:亩施有机肥3427—3550kg 和 P₂O₅11.2—11.5kg 做小麦底肥,N15.1—15.5kg（小麦季占4/5花生追肥占1/J,小麦肥配为小麦底肥和小麦拨节期追肥各占1/2）.小麦和葆生行距均为40cm,小麦亩播量10.3kg;花生亩密度8000穴,每穴2粒.更多还原

【Abstract】 Three models for high-yield of wheat and peanut,and high total value of interplanting output were set with gyratory design and the parameters which were obtained by field exper- iment.F-test for the models all passed by 1%.Through the simulation and sieving for the optimization of the models with the computer,the best synthetic agronomic measures can be worked out:under the row width of wheat and peanut was 40 centermetres,if organic manure was 3427-3550kg/mu,and phosphate fertilizer 11.2-11.5kg/mu,used for the bottom ap-plication of wheat,Nitrogenors fertilizer 15.2-15.5kg/mu,wheat sowing norm 10.3kg/mu.peanut density 8000 bunchs/mu,one bunch have two grains,then wheat yield of>250kg/mu,peanut ottwrn of>300kg/mu.total value of interplanting output of>600 yuan/mu could be achieved.更多还原
