| 摘 要： | 采用田间对比试验,研究不同机插密度对陵两优102群体结构和产量的影响。结果表明:不同机插密度对双季早稻陵两优102的分蘖消长、生长发育、穗粒结构和产量均有影响。在该试验条件下,陵两优102机插株行距宜选择10 cm×25 cm的规格,实插2.55万蔸/667m~2左右,每蔸插2~3苗,如此构建的群体结构较合理,单产较高,可达517.8 kg/667m~2。

| Abstract: | The effects of different machine-transplanted density on population structure and yield of Lingliangyou102 was studied by field comparison experiment. The results indicated that different machine-transplanted density have influence on tiller, grow, efficient spike and yield of double cropping rice. Under the experimental conditions, machine transplanting spacing should be 10 cm×25 cm, the machine-transplanted density of 382500 clump/hm2, 2-3 seedling per clump is suitable, with reasonable population structure and higher yield, 7767 kg/hm2. |
