双季超级晚稻的经济效益、产量构成及高产技术分析
Analysis of Economic Efficiency,Yield Components and High-yielding Techniques of Double Cropping Super Late Rice
【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。
【Abstract】 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 according to the practice experience and the experiment.
