杂交水稻高产栽培研究进展

高产栽培理论与技术对于提高杂交水稻产量有着重要意义。优化杂交水稻群体质量,扩大杂交水稻库容量,提高光合叶面积指数和光能利用率,增强杂交水稻根系活力,延缓根系和叶片衰老,提高杂交水稻库容的有效充实度,可实现杂交水稻高产。杂交水稻高产栽培实践中形成了以精确定量栽培、强化栽培、三定栽培为代表的等高产栽培技术体系。杂交水稻高产栽培也存在栽培技术与我国农村发展不适应,以及与农业生态环境保护不很好协调的矛盾。精准化栽培、生态化栽培和轻简栽培将是我国今后水稻生产发展急需技术。

Research Progress of High Yielding Cultivation of Hybrid Rice

The theories and technologies of high yield cultivation are important for us to enhance the yield of hybrid rice. We can achieve target of high output for hybrid rice via expanding rice population sink capacity, optimizing rice populations quality, increasing photosynthetic leaf area index and energy efficiency, enhancing the rice root vigor to retard roots and leaves aging and improving the effective capacity of rice population sink capacity. The precise quantitative cultivation and SRI and "San-Ding" cultivation technologies were formed in high-yielding hybrid rice cultivation practice, which were greatly to show the application of the above theories of rice cultivation. The high-yielding hybrid rice cultivation does not adapt to rural development requirement, and agricultural ecological environment protection can not be well coordinated in present. Precision planting, ecological cultivation, simplified and high efficiency cultivation will be the urgent need technologies in the future in rice production practice in China.
