不同播期对绿豆品种洮绿5号生育性状和产量的影响

Effect of Different Sowing Date on Growing Character and Yield of Mung Bean Variety Taolv No. 5

[目的]研究不同播期对绿豆品种洮绿5号生育性状和产量的影响。[方法]以绿豆品种洮绿5号为供试材料,通过分期播种,研究不同播期对洮绿5号生育期、株高、叶片数、百粒重、单株荚数以及产量的影响。[结果]随着播期的推迟,生育期逐渐缩短,株高、叶片数、百粒重、单株荚数和产量均呈先增加后降低的趋势。[结论]该品种在吉林省的适宜播期为5月26日,此时播种生育期适中,植株生长状态好,穗粒结构最优,产量最高,种植效益最高。

[Objective]The aim was to study the effect of different sowing date on growing characters and yield of mung bean variety Taolv No.5.[Method]With Taolv No.5 as tested material,the effect of different sowing date on growth period,plant height,leaf number,100-seed weight,pods per plant and yield was studied by stages seed-times.[Result]With the delaying of sowing date,growth period gradually shorten,and growing characters including plant height,leaf number,100-seed weight and pods per plant and yield showed a first increase and then decrease trend.[Conclusion]The optimal sowing date of Taolv No.5 in Jilin province is May 26,which can get good growth state,the optimal spike-grain structure,the highest yield and the highest planting benefit.
