Research on High-Yield Seed Cultivation Techniques for the Inner Mongolia Native Plants Astragalus dahuricus
摘要
Abstract
Astragalus dahuricus(Pall.)DC.,a high-quality native plant in Inner Mongolia,is widely used in ecological restoration.However,research on its cultivation remains limited.To promote the conservation-based development of native grass seed resources and optimize the breeding technical system in Inner Mongolia,this study adopted a three-factor,four-level orthogonal experimental design to investigate the effects of row spacing(40,50,60,70 cm),sowing rate(10,15,20,25 kg/hm²),and nitrogen-phosphorus-potassium(The ratio of N∶P2O5∶K2O is 18∶18∶18)compound fertilizer application rate(105,210,315,420 kg/hm²)on seed yield and its component.The results demonstrated that the highest seed yield was achieved under a row spacing of 50 cm,a seeding rate of 10 kg/hm²,and a fertilization rate of 210 kg/hm².Among these factors,the impact on seed yield followed the order:row spacing>fertilizer rate>seeding rate,with the seeding rate having no significant effect.Grey correlation analysis of the seed yield components showed the following order of relational degree:number of pods per inflorescence>number of inflorescences per unit area>thousand-seed weight>number of seeds per pod>number of florets per inflorescence.关键词
