春小麦新品种“吉麦2号”最佳农艺措施的研究

THE BEST AGRONOMIC PRACTICES OF NEW SPRING WHEAT VARIETY “JIMAI No.2”

本试验采用二次回归正交旋转组合设计研究了密度,氮肥和磷肥对吉麦2号小麦新品种产量的影响并建立了诸因素对产量的生产函数回归模式.在此基础上,通过数学模拟的方法初步确定了吉麦2号的最优高产综合农艺措施及其丰产潜力。

An experiment wars conducted in the Experimental Station in 1987 to investigate relationships of plant stands,P and N fertilizer with wheatyield.A quadratic regression orthogonal design was employed and produc-tive function model of wheat yield to doses of the three factors was estab-lished.The optimal agronomic practices and yield potential of“JIMAINo.2” was found and estimated,based on the Method of MathematicImitation.
