播期对新农菜豆1号农艺性状及品质的影响

研究了不同播期对菜用大豆农艺性状及品质的影响。结果表明,随着播期的推迟,菜用大豆生育期缩短,株高和始荚高度呈增加趋势,茎粗、节数、分枝数、分枝总长度呈减少趋势,单株荚数、单株粒数、单株粒重降低,百粒鲜重与播期关系不显著;菜豆籽粒中的蛋白质含量增加、淀粉含量减少、可溶性糖含量先增后减。以第2播期处理产量最高,为13 594.20 kg/hm2,适宜播期应为4月10~25日。

Effect of planting date on the agronomic characters and quality of vegetable soybean

This experiment studied the effect of the agronomic character and quality of different planting date of vegetable soybean Xinnongcaidou 1. The study result showed that the growing period was shortened along with the planting date postponing. The plant height and the height of initial pod stage was increased. Stem thickness, nodes, the branch number, the length of branch was decreased along with the planting date postpone. Pod number, seed number and seeds weight of single plant were decreased along with the planting date postponing. The relation between fresh weight of 100 seeds and planting date was not significant; Protein content was increased, starch content was decreased, soluble sugar content was increased and decreased successively in seeds of vegetable soybean, The yield of the second planting date was the highest, namely, 13 594.20 kg,/hm^2. Optimal result was achieved with the treatment of planted on April 10 th - 25 th.
