摘要
前言菜用大豆(Glycine max L.)俗称毛豆,我国南方普遍栽培。早熟品种如“四月拔”、“五月拔”一般在2月下旬至3月上旬播种,6月上旬开始收获。其种子在采收后要经过高温、多雨的夏季而使生活力下降。而且翌年早春播种,由于气温低和土壤湿度大,常常发生出苗慢、出苗率低,甚至烂种的现象,影响全苗和壮苗,是生产上存在的重要问题。本研究的目的,即是通过采用几种不同的简易贮藏方法比较,来寻找有效地防止菜用大豆种子越夏贮藏过程中活力下降的措施。
In this study it was foount that dry seeds (silica gel desiccation or dry seeds, 6.5% moisture content, in moisture-proof PE film bag) may maintain high germinative power and germination percentage and vigor index even after stored for two hot and wet summer seasons. The germinative percentage of cloth bag storage seeds was only 55% after one summer storage. Its Vigor index was also low. Its germination percentage was only 12.2% when germinated at 15℃ and wet conditions for 4 days. This indicated that the seeds could not be used as sowing seeds. When seeds were stored in air tight film bag, seed moisture content would hardly be affected by environmentaal humidity and remain stable. so dry seeds stored in tight PE film bag was found to be a simple but effective method of preventing soybean vigor loss through summer in central and south China.
