水稻叶龄模式是以水稻主茎叶龄期为指标,利用相关生长关系,诊断器官生长进程,并采用“小群体、壮个体”的高产栽培途径,确定播种量、基本苗以及肥水运筹等看苗诊断技术。多年来对大量品种的观察,发现不同总叶数的品种在同一叶龄期的生育进程不同,而同一总叶数类型的不同品种,同一叶龄期的生育进程相同。因此,同类型品种,可以根据叶龄进程,把水稻的生育期、器官建成、产量因素形成等模式化,因而把生产上繁杂的品种归纳为6类生育进程的叶龄模式,作为培育高产群体诊断依据,并为实现形态指标数量化、规范化奠定基础。
Rice leaf age model is based on the main stem-leaf age of rice as an indicator, the use of the relationship between the growth of the diagnosis of organ growth, and the use of “small groups, Zhuang individuals,” high-yield cultivation methods to determine the sowing rate, basic seedlings and fertilizer operation Miao diagnostic techniques. Over the years the observation of a large number of varieties found that different total leaf number of varieties in the same leaf age fertility process is different, while the same total leaf types of different varieties, the same leaf age fertility process the same. Therefore, the same type of varieties, according to the leaf age process, the growth of rice, organs, the formation of yield factors such as pattern, and thus the production of complicated varieties into six types of fertility process leaf age model as a breeding high-yield groups Diagnosis basis, and to achieve the quantitative and morphological indicators to lay the foundation.
