摘要: 运用二次正交回归旋转组合设计,于2017年和2018年对河套灌区玉米一穴双株增密高产栽培产量与密度、氮肥和磷肥用量关系进行了研究,并建立了产量与各因素之间的数学模型。结果表明:以两年试验建立的模型进行优化筛选,获得河套灌区玉米一穴双株增密高产(产量≥16 500 kg/hm2)栽培技术措施的指标为:密度96 675~97 920 株/hm2,氮(N)420.75~431.55 kg/hm2,磷(P2O5)288.30~299.70 kg/hm2

Abstract: By using a quadratic orthogonal regression rotary combination design,the relationship between yield and density,andnitrogen and phosphorus fertilizer consumption by maize in Hetao irrigation area planted by technology of double plants in one hole,were studied in 2017 and 2018.Mathematical models between yield and various factors were established.After optimization and selection of models for the two years,the technical indexes for maize planted by double plants in one hole in Hetao irrigation area were obtained.The indexes for yield ≥16 500 kg/hm2 showed that density is 96 675-97 920 plants/hm2;while N dosage is 420.75-431.55 kg/hm2;and P2O5 dosage is 288.30-299.70 kg/hm2.
