籼型超级杂交水稻高产栽培研究进展

Development of High Yielding Cultivation Researches in Indica Super Hybrid Rice

对中国籼型超级杂交水稻高产栽培生理、生态适应性和高产栽培技术研究成果进行分析,指出现已育成的籼型超级杂交稻在我国南方多种生态区域作一季稻种植产量达到12t.hm2,表现出根系旺盛、分蘖力强、足穗大穗、源库协调、耐肥抗倒、以及前期能早发和后期抗早衰的潜在高产优势。有关栽培生理、生态适应性和栽培技术的研究结果显示,超级杂交稻在保持较高经济系数的同时,通过增加生物产量是超高产栽培的主要途径。进一步研究超级杂交稻的产量稳定性、产量形成机理、适宜种植区域,群体诊断指标、优质与高产相协调的关键栽培的技术等,对于建立超级杂交稻的栽培理论与技术体系,具有十分重要的科学意义和应用价值。

This paper summarized the research results of high yielding physiology, ecological adaptation and cultivation technology in indica super hybrid rice （1SHR）. At the present, over 12 t·hm^-2 of ISHR has been recorded in different ecological regions of Southern China. And ISHR displayed vigorous root system, strong tillering capacity, proper panicle number and big panicles, coordinated ratio of source to sink, fertilizer tolerant and lodging resistant as well as the growth vigor at early stage and senescence free at late stage. The research results showed that high dry matter production as well as high economic coefficient is only one path to increase yield of ISHR. This paper also pointed out that to study the yield stability, yield formation mechanism, optimum regions grown, canopy index diagnosed as well as the key techniques of the coordinated relation between high yielding and good quality further have the important scientific meaning and application value to set up the cultivation theory and technology system.
