摘要
通过对秋大葱不成株成因及其对产量影响的研究,发现遗传和栽培因素同时影响大葱不成株的产生.强遗传势区位人工辅助授粉可减少后代不成株率;葱株分级栽培及调整种植密度(尤其是株距)是目前生产上降低大葱不成株率的主要措施.
The effect of little-plants of Welsh Onion （Alliums fistulosum L.）on yield is studied.Considers that the factors on heredity and cultivating are the important cause of little-plants of Welsh onion.Puts forward that plants of the classified cultivating and longer row spacing of plants are the most measure on decreasing little-plants on cultivating.
