摘要
采用育苗移栽的方法,单因素随机区组试验设计,研究了在种植密度一定的条件下,每穴种植株数对紫苏生长发育及产量形成的影响。结果表明:1)1穴多株栽植可降低紫苏主茎高度,基部和中部的主茎节位上移,分枝上移。2)1穴多株栽植扩大了穴距,有利于中下部分枝成花、成穗,可提高群体中下部子粒产量和品质。3)3个处理间紫苏子粒产量差异极显著。PX3处理的子粒产量最高,达2 366.8 kg/hm2;其次是PX5处理,子粒产量为1 475.85 kg/hm2,分别比PX1处理增产43.35%和10.07%。
Adopt with the single factor random design, and under the condition of certain planting densities ,this experiment influence of per cave stubs number to perilla growing and yield constitute was studied The result showed： several stubs per cave can reduce stalk altitude and the branches can move upward. The number of blooms and spikes in lower branches increased in planting several stubs per cave. The yield difference between three treatments showed great significance. The yield in PX3 is the tallest, as high as 2 366.8 kg/hm^2 ,PX5 1 475.85kg/hm^2, Compared with PX1 the yield increased 43.35% and 10.07%o
