| 摘 要： | 以东农423（V7）为供试品种，在水稻三超栽培条件下，设A、B、c等密度相同而行株距不同的3个处理，研究了宽行处理A（42cm×14．3cm）和B（36cm×16．7cm）与窄行处理C（30cm×20cm）对水稻生育及产量的影响。结果表明：处理间的茎蘖动态、叶面积指数、叶绿素含量、干物质积累、产量及其构成因素等均呈A〉B〉C趋势，说明宽行栽培更有利于水稻的超高产。 |
| 关 键 词： | 水稻三超 宽行栽培 超高产 |

| Abstract: | Three treatments of wide space treatments A （42 cm× 14.3 cm） and B （36cm× 16.7 cm） and narrow space treatments of C （30 cm× 20 cm）, which were in the same density but different row spacing and intrarow spacing, were designed to study the effect of wide space on the growth and yield of rice with the variety Dongnong 423 （V7） under 3-S cultivatons. The results showed that the dynamic change of tiller growth, leaf area index, Chlorophyll content, dry matter weight, yield and yield component of different treatments were A 〉 B 〉 C. In general, wide space planting is advantageous to super high yield of rice. |
| Keywords: | 3-S cultivation wide space planting super high yield |
