在桂林对深两优5814的特征特性进行了观察,同时设置了(23.3～40.0)cm×13.3 cm 6个密度处理,研究不同栽插密度对深两优5814产量、生育期及主要性状的影响。结果表明,不同栽插密度对深两优5814的生育进程、全生育期产量无显著影响,以密度为33.3 cm×13.3 cm处理产量稍高,说明该组合栽插方便,有利于该组合的推广。提出了该组合基于叶龄模式的精确定量栽培技术,并进行了成功示范。
The characteristics of Shenliangyou 5814 were observed in Guilin, and the density of (23.3 ~ 40.0) cm × 13.3 cm 6 was set to study the effects of different transplanting density on the yield, growth period and main characters of Shenliangyou 5814 . The results showed that different transplanting density had no significant effect on the yield and growth during the whole growth period of Shenliangyou 5814, and the yield was slightly higher at the density of 33.3 cm × 13.3 cm, which indicated that the combination was convenient for planting and promoted the popularization of the combination . The precise quantitative cultivation technique based on leaf age model was proposed and the successful demonstration was made.
