摘要
试验示范结果表明,双季超级晚稻的经济效益比常规杂交稻增加26.66%;超级晚稻的每穗粒数对产量影响最大,其次是结实率;根据生产实践经验和有关试验结果,提出了超级晚稻的高产栽培技术。
The result of the experiment showed that the economic benefit of double cropping super late rice was 26.66% higher than that of conventional hybrid rice. Kernels per spike had the most effect on yield, and the following was seed setting rate. The high - yielding techniques of super late rice were put forward aeeording to the practice experience and the experiment.
