摘    要:研究了早稻不同基础群体(基本苗)和结构(穴数和本数)下的产量及其形成过程.结果表明,不同基础群体和结构下的早籼稻产量有显著或极显著的差异;在每公顷30~75万穴之间,产量均以每穴种植4株为最高;当每穴株数相同时,产量均随每公顷穴数增加而增加;在基础群体大小相等时,多穴少本群体结构的产量比少穴多本的高,这在基础群体较大时尤为明显,因为多穴少本群体结构更能协调群体与个体的关系,有利于个体的发展

关 键 词:早籼稻  群体  结构  产量

Abstract:The yield, its becoming process and yield component of early indica rice under different size of basic population were studied in this experiment. The result showed that the yield and its component of early indica rice were significantly deferent under different size of basic population.Among each number of planted hill from 300 thousands to 750 thousands per hm 2,the highest yield appeared in 4 plants per hill. When the number of plants per hill is equal,the yield was incresed with increse of number of hill per hm 2; When the size of basic population was equal,the yield of a basic population of more hills per hm 2 and fewer plants per hill was higher than that of a basic population of fewer hill per hm 2 and more plants per hill. it was more obvious when the size of a basic populalion was more. The reason for this is that a basic population of more hill per hm 2 and fewer plants per hill can more suffierently coordinate the relationship of population with individual plant than that of fewer hill per hm 2 and more plants per hill, Therefor,it was beneficial to growth and development of individual plant.
Keywords:early  indica  rice  population  component  yield
