Vicia unijuga, commonly called two-leaf vetch, is a species of flowering plant in the legume family. It is native to eastern Asia, where it is widespread, its range extending through China, Korea, Mongolia, Japan and Russia.
A method for establishing a seed field of vicia unijuga adapted to different ecological zones
The application discloses a kind of different ecological region's Bunge grass seed field planting method, belong to pasture seed production technical field.The method is aimed at the environment difference of temperate saline-alkali prone area and temperate typical grassland area, based on the allelopathic effect of acid substance to Bunge grass and physiological and biochemical interaction law, and optimally constructs two kinds of composite acid initiation system of ferulic acid+salicylic acid+protocatechuic acid saline-alkali coordination type and chlorogenic acid+hydroxybenzoic acid+coumaric acid grassland coordination type.The application makes the emergence rate to be increased to 85% or more, seed yield is increased by 20%-30% compared with conventional extensive planting, standard germination rate reaches 90% or more, neatness is 75% or more, large-diameter seed accounts for 60% or more, small-diameter and shriveled grain accounts for 10% or less, and the coefficient of variation of grain size is low, which provides green and efficient technical support for native grass seed breeding.
