玉米大豆间作复合群体优化配置与生产力研究

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数进行分析，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。证明优化结构匠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，发挥其最高生产力水平。

A STUSY ON OPTIMUM STRUCTURE DISPOSITION OF INTERCROPPINGS OF MAIZE-SOYBEAN COMPLEX AND ITS PRRODUCTIVITY

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.
