本研究于1979—1981年在东北农学院进行。通过20个无限结荚习性及有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)、不同冠层光截获率(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)以及主茎荚/节(PNMS)等产量性状进行多元回归方程集合的分析,明确了该光合生理生态性状对此等产量性状形成的效应。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斤左右的无限和有限结荚习性大豆的顶荚形成初期的理想株型优良冠层模式。为大豆理想株型育种提供了科学依据。
This study was conducted in Northeast Agricultural College from 1979 to 1981. Through photosynthetic physiology (LAI), RLI (canopy interception rate) and RDMP (canopy photosynthesis) of 20 pod-tolerant and limited-pod-tolerant soybean cultivars, The ecological traits such as NPP, NSP, SWP, SSR, PMS and PNMS were all higher than those of the control The analysis of the set of multivariate regression equations clarified the effect of the photosynthetic physiological and ecological traits on the formation of these yield traits. Furthermore, based on the ecological types such as growth period, pod habit, leaf shape, seed size, chemical quality and pest resistance of soybean in Harbin area, an infinite and limited pod Habitat Soybean pod formation of the early ideal plant type excellent canopy pattern. Soybean ideal plant type breeding provides a scientific basis.
