菜用大豆品系干物质积累及产量比较试验

对不同熟期6个菜用大豆品系的叶面积、干物质积累及产量进行比较。结果表明:早熟品系叶面积指数高峰值来的早,峰值低,干物质积累量少,植株矮小;晚熟品系叶面积指数峰值来的晚,峰值高,干物质积累量大,植株高大。早熟品系C2和新农菜豆1号、晚熟品系J7和Z03在满粒期收获鲜荚13 230.0~15 255.0 kg/hm2,子粒蛋白质含量37.62%~43.83%,粗脂肪含量17.83%~18.94%,综合性状较优,可供生产选用。

Comparative Tests on Dry Matter Accumulation and Yield of Vegetable Soybean Lines

Leaf area,dry matter accumulation and yield of six vegetable soybean lines at different maturing stages were compared in the field.The study result showed that peak of LAI of early maturing lines was early,peak value was low.Few dry matters were accumulated,plant was low and small,the peak of LAI of late-maturing lines came up late,its peak value was high.Great number of dry matters was accumulated,its plant was high and big.Yield of fresh pods from the early-maturing lines C2 and Xinnong vegetable soybean 1,late-maturing lines 17 and Z03 in full ripe stage reached 13 230.0-15 255.0 kg/hm2.The seed protein content reached 37.62%-43.83%.The crude fat content reached 17.83-18.94.The vegetable soybean lines can be selected and used in production according to the predominant comprehensive properties.
