摘要
甜菜45cm行距种植,可增加单位面积保苗株数,且分布均匀:冠层结构合理,光能利用率高,且时间长,净同化产物分配率高;群体与个体发展较协调,中等高糖块根多,达到了缩行增株、增产、增糖作用;同时又便于机械化作业,使甜菜生产力明显提高。
It can increase the stands of plant population in the unit area and uniform distribution when sugarbeet planting in 45cm row space. The structure of sugarbeet lop was rational, the utilization ratio of light energy was higher and time longer, the distribution rate of net assimilates higher, development of the population and individual was well coordinated, the roots with higher sugar content were more. It reached the role of reducing the row space to narrow and adding plants, increasing root yield and sugar content. At same time, it can easy to do mechanization operation and productivity of sugarbeet raised significantly.
