摘要
研究了不同品种和密度对超级杂交稻强化栽培的影响。结果表明:超级杂交稻强化栽培品种与密度间交互作用差异不显著,中浙优1号抛秧密度112500穴/hm2产量最高,适合广西进行超级杂交稻强化栽培。在广西桂中和桂北地区,早熟的新两优6号也可作为超级杂交稻强化栽培。
The effect of different varieties and densities on the system of super hybrid rice intensification was determined. Results showed that there were not obvious interaction differences between variety and density of super hybrid rice. The yield of Zhongzheyou No. 1 was the largest with the density of 112. 5thousand holes/hm^2. It was an appropriate variety for the system of super hybrid rice intensification in Guangxi. In the central part and the north part of Guangxi., Xinliangyou No. 6 could also be adopted as the super hybrid rice intensification.
