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(Madagas-car)提出的一种新的栽培方法,而且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,降低了垩白粒率,并且能省工省种,能增收节支。由于中国各地的生态条件相差大,通过四川、浙江和江西等十多个省市的研究,都研究得出了适合各地的改良水稻强化栽培技术,并在各省市都得到了广泛的推广应用。
System of Rice Intensification (SRI) is a new cultivation method proposed by Father Henri de Laulanie in Madagas-car in the 1980s, and has been applied to obtain better yield increase effect. In recent years, Experiments have taken place in Indonesia and other countries as well as in China, initially showing greater potential for increasing production and breaking the traditional habit of planting more in China. Through the combination screening and factor analysis of suitable intensified cultivation techniques, the experimental results show that the technology has strong adaptability in China and good stimulation effect, improves the ventilation and light in the field, reduces the incidence of sheath blight and increases the yield of rice plants Photosynthetic capacity, increased root activity, enhance the transport of nutrients, improve the rice milled rice rate, reducing the chalky grain rate, and can save provincial species, can increase income and reduce expenditure. Due to the large difference in ecological conditions across China, studies on more than ten rice provinces and cities in Sichuan, Zhejiang, and Jiangxi have all resulted in the study of improved rice cultivation techniques that are suitable for all regions and have been widely popularized and applied in various provinces and cities.
