【摘要】 采用二次回归旋转组合设计进行试验,对新育成优质高产春小麦张春17号高产综合农艺措施进行了研究.通过田间试验测定参数,利用计算机技术对试验数据进行处理,建立产量函数模型.经计算机模拟寻优,筛选出了产量≥6750kg/hm~2的最佳农艺措施组合方案并确定了置信域.为优质小麦张春17号高产栽培的数量化、指标化提供了科学依据,在生产应用中可良种良法配套进行示范推广.表2,参3.更多还原

【Abstract】 The complex agronomic measures of newly breeding good quality high - yield spring wheat-"zhangchun No. 17" were studied according to quadratic regression rotation design experi-mence. The yield function model was established according to parameters through field expriemen-tal tests and data that treated by computer techniques. The best agronomic measures complex project that yield over 6750kg per hm2 was selected, cofidence region was developed by using computer imitation. It gives a scientifical basis for quantity and index of high -yield cultivation of good quality "zhangchun No. 17". Mixed good varieties with benefical methods, demonstrated and extended in general practice application.更多还原
