摘要
通过秋大豆的群体生产结构、生长分析、生育特点、干物质积累与分配 ,不同品种和播种期两因子试验的研究 ,表明各品种均以鼓粒期积累的干物质最多 ,达一半以上 ,分配到荚果中的有机物质也是以鼓粒期较多。贡豆 89- 1干物质积累较多 ,同时后期分配到子粒中比例较高 ,产量较高。栽培上宜选用贡豆 89- 1和浙春 1号等早熟品种 ,同时必须在 7月 30日前尽早播种 ,才能获得高产高效。
We had carried out an experiment on autumn soybeans about growth, developing characteristics, accumulating and dry substance distributing by factorial design taking variety and sowing date as two factors.The result shows that more dry substances of all varieties are accumulated on pod filling period, reaching over 50%, and more substances are distributed to pods in this period. Substances accumulated by 'Gongdou89-1' is higher, and more were distributes to seeds in later stages and the yield is high. Early varieties, such as ' Gongdou89-1' and ' Zhechun-1' would be better to be chosen in culture, and their sowing date should be before July 30 to achieve high yield and economic results.
