中国水稻强化栽培技术的研究

Studies of China System of Rice Intensification

水稻强化栽培体系(System of Rice Intensification,SRI)是20世纪80年代由Henri de Laulanie神父在马达加斯加(Madagascar)提出的一种新的栽培方法,水稻强化栽培体系在马达加斯加的应用获得了较好的增产效果,近年在印尼等国以及中国都进行了试验,初步显示了较大的增产潜力,打破了在中国的较大栽培密度的传统习惯。通过适宜强化栽培技术的组合筛选和因素分析,试验结果表明:该技术在中国适应性强,增产效果好,改善了田间的通风透光,降低了纹枯病的发病率,增加了水稻植株的光合能力,增加了根系活力,加强了营养物质的运输,提高了稻谷的整精米率,降低垩白粒率,并且能省工省种,增收节支。由于中国各地的生态条件相差大,通过四川省、浙江省、江西省等十多个省市的研究,得出了适合各地的改良水稻强化栽培技术。

The system of rice intensification （SRI） is 80 years of the 20th century by the Father Henri de Laulanie Madagascar proposed a new cultivation method, system of rice intensification in Madagascar＇s application was a better yield effect, in recent years, in Indonesia, China and other countries had carried out tests showed a larger initial yield potential, breaking the larger of Chinese traditional practice of planting density. Appropriate cultivation techniques through a combination of enhanced screening and factor analysis results showed that： the technology in China, strong adaptability and good yield, improved field of air and light, reducing the incidence of sheath blight, rice plants increased photosynthetic capacity, increasing root activity, enhancing nutrient transport, increase the rice milled rice, chalky rice rate reduction, and to save both labor and species, to increase revenue. As Chinese ecological conditions around the big difference, through Sichuan Province, Zhejiang Province and Jiangxi Province and more than 10 cities, which were studied around the improvement obtained for rice intensification technology.
