| 摘 要： | 本试验采用四因素二次通用旋转组合设计的方法,研究了影响耐密型玉米高产的氮、磷、钾肥施用量和种植密度,获得了耐密型玉米产量形成的函数模型及高产农艺措施组合方案。结果表明:种植密度对耐密型玉米产量影响最大,其次是磷肥、氮肥和钾肥。亩产700公斤以上的栽培措施为:市施纯 N15.4～17.0kg、P_2O_58.1～8.8kg、K_2O_3.5～4.0kg、亩保苗4265～4347株。

A PRELIMINARY STUDY ON MODEL OF YIELD FUNCTION OF HIGH YIELDING SYNTHTICAI AGRONOMIC MEASURES FOR THE HIGH DENSITY-TOLERANCE CORN |

| Abstract: | The doses of N,P and K fertilizers and plant density affecting the yield of high density-tolerance corn were studied using four factor, quadratic,general rotation combination design.The yield function model of high density tolerance corn was built up,and an higher yielding schem- of agronomic measures was obtained. The experimental results showed that plant density was a vital agricule tural factor for the corn to reach the highest yield.Application of p,N and K fertilizer was important for high yield.Yield of 700 kg/muor more would be obtained by means of plant density of 4265～4347 Plants/mu with application of N 15.4～17.0 kg/mu,P_2O_5 8.1～8.8 kg/mu and K_2O 3.5～4.0 kg/mu. |
