摘　　要：为了研究杂交籼稻在高海拔地区的生长特点,采用水稻强化栽培方法对中优838、香早优2017、京福I优明86进行了最适种植密度和最佳移栽叶龄的试验。结果表明,在安顺地区进行强化栽培,应选用穗粒兼顾型品种和穗重型品种,采用4～5叶龄的带蘖秧苗移栽,通过适当提高栽植密度（9 000～10 000穴/667m^2）、增加有效穗的方式,进一步优化穗粒结构,协调源、库、流关系,充分发挥其在穗粒数方面的优势来获得高产。In order to study the growth characteristics of indica hybrid rice in high altitude areas, the test was conducted on density and transplanting leaf age of Zhongyou 838, Xiangzaoyou 2017 and Jingfu I Youming 86 by the system of rice intensification（ SRI） to find out the optimum planting density and the optimal leaf age for transplant. The results showed that the researchers should choose grain oriented varieties and heavy panicle varieties and transplant 4～5-leaf seedling with tillers by increasing the plating density（9 000～10 000 points /667m^2） and effective panicles. Furthermore, optimize the grain structure and coordinate the relationships of source, sink and flow well, and give full play to its advantages in kernels per spike to obtain high yield.
