摘 要:通过随机区组与二次旋转组合设计的分阶段两年定位试验,对间作群体产量,田间生长动态,群体结构与生产力,土壤微生物种群变化等一系列指标进行分析,建立了反映产量、产值、纯收入等多目标性状的数字模型,得到了间作复合群体的理想搭配模式及适宜取值范围。证明优化结构的间作复合群体可使种内种间矛盾趋于最小,形成高功能高效益的间作体系。By means of randomized bolck design and rotational combinatorial design,the fixed point and position experiments were carried out i n two stages between 1993 1994 seasons.Some indexes were obtained such as the y ield of intercropping colony,growth dynamics colony,structure and productivity o f soil fertility,etc.in this study.The mathematical models were also gained in y ield and optimization was done. Factors that influence interplanting yield as we ll perfect supplement patterns of these factors along with its confidence were a cquired.
