汕优63是当前我省麦茬中稻地区正在大力推广的一个籼型杂交组合,其突出优点是适应性较广,繁茂性较强,结实率较高,粒重较大,因而在大面积生产中具有明显增产效果,深受群众欢迎。但是,该组合也由于存在植株较高,叶片宽大,容易引起中后期群体与个体生长矛盾等弱点,因此生产上也提出了应该采取什么途径,建立什么样的群体结构才有利于发掘其增产潜力以获得高产稳产的问题。 Shanyou 63 is a indica hybrid combination that is being popularized in the region of middle rice in wheat stubble in our province at present. Its outstanding merit is that it has wide adaptability, strong lushness, high seed setting rate and large grain weight, therefore, With a significant increase in production, welcomed by the masses. However, this combination is also due to the existence of higher plants, leaves wide and easy to cause the contradiction between groups and individuals in the late growth and other weaknesses, so the production also put forward what should be done to establish what kind of community structure will help explore its potential yield In order to obtain high yield and stability of the problem.
