以超级稻“盐丰47”为材料，采用小区对比试验方法，探讨了不同移栽基本苗对机插水稻生育性状、产量的影响。结果表明，增加移栽基本苗，有利于单位面积最高茎蘖数与收获穗数、齐穗期群体叶面积指数与有效叶面积率以及齐穗期与成熟期干物质积累量的增加；不利于茎蘖成穗率、齐穗期高效叶面积率以及齐穗后干物质积累量占籽粒产量百分比的提高。移栽基本苗86.71×104/hm2的处理B3获得单产10.27 t/hm2，比处理B4、B2、B5、B1分别增产0.7%、2.0%、2.4%、5.1%。
以超級稻“鹽豐47”為材料，採用小區對比試驗方法，探討瞭不同移栽基本苗對機插水稻生育性狀、產量的影響。結果錶明，增加移栽基本苗，有利于單位麵積最高莖蘗數與收穫穗數、齊穗期群體葉麵積指數與有效葉麵積率以及齊穗期與成熟期榦物質積纍量的增加；不利于莖蘗成穗率、齊穗期高效葉麵積率以及齊穗後榦物質積纍量佔籽粒產量百分比的提高。移栽基本苗86.71×104/hm2的處理B3穫得單產10.27 t/hm2，比處理B4、B2、B5、B1分彆增產0.7%、2.0%、2.4%、5.1%。

The effect of translating basal seedlings on growth and yield of mechanical transplanting rice were researched by plot comparative test which using Yanfeng47 as experiment material. The result indicated that increase translating basal seedlings was conducive to increase the highest tiller number per unit area and effective panicles, LAI of full heading stage and dry matter accumulation of full heading stage and maturity stage and effective leaf area rate, then it against enhance the effective panicle percentage, high-efficiency leaf area rate of full heading stage and the rate that dry matter accumulation in the grains yield after heading. When the translating basal seedlings were 86.71×104/hm2, it can achieve the yield which was 10.27 t/hm2, was increased 0.7%, 2.0%, 2.4% and 5.1% than B4, B2, B5 and B1 respectively.
