通过哈尔滨地区15个无限结荚习性大豆品种顶荚形成初期的不同冠层叶面积指数(LAI)、不同冠层光截获(RLI)、全冠层光合生产率(RDMP)等光合生理生态性状对株荚数(NPP)、株粒数(NSP)、株粒重(SWP)、粒茎比(SSR)、主茎荚数(PMS)及主茎荚/节(PNMS)等产量性状多元回归方程集合的分析,明确该光合生理生态性状对此等产量性状形成效应及其对株型改良的影响。进而,在哈尔滨地区大豆生育期、结荚习性、叶形、种粒大小、化学品质及抗病虫性等生态类型的基础上,初步建立了哈尔滨地区亩产450斤左右的无限结荚习性大豆顶荚形成初期的理想株型优良冠层模式。试图为大豆理想株型育种提供一定科学依据。
Through the photosynthetic and physiological characteristics of different canopy photosynthesis (RLI) and canopy photosynthetic productivity (RDI) at the early stage of pod formation in 15 immortalized soybean cultivars in Harbin, NPP, SWS, SSR, PMS and PNMS were calculated by using a set of regression equations Of the photosynthetic physiological and ecological traits to clarify the formation of these yield traits and its impact on plant type improvement. Furthermore, on the basis of ecological types such as growth period, pod habit, leaf shape, seed size, chemical quality and pest and disease resistance of soybean in Harbin area, an initial yield of about 450 kg of unlimited pod habit soybean in Harbin The ideal pod type in the early pod formation canopy model. Trying to provide a scientific basis for the ideal plant type breeding of soybean.
