    摘要:

    本试验以紧凑型玉米先玉335为试验材料,于吐丝期对其进行剪1/4叶片、2/4叶片、3/4叶片和剪2/4穗等减源和减库处理,研究改变源库关系,源库调节对玉米子粒产量及相关因素的影响。结果表明:源库变化对先玉335子粒干重和产量的影响均为源>库;对子粒体积的影响则为库>源。故维持玉米群体的源库平衡,保证总粒数和吐丝后干物质积累量是紧凑型玉米高产栽培的重要措施之一。

    Abstract:

    In this experiment,the compact type maize variety ’Xianyu 335’ was chosen as the test material, and 1/4,2/4,3/4 of the leaves were cut and 1/2 of the spikes were cut Effects of changes of source and sink on yield of maize were studied.The results showed that effect of source reduction treatments on dry weight and yield was bigger than that of sink reduction treatments,whereas effects of sink on volume of grain was bigger than that of source.It is obvious that keeping a relative balance between source and sink and keeping more grains and storing more dry matter is an important cultural measure in high-yield production of maize.
