摘　　要：20 0 1年用优质两系杂交稻两优 36 3在贵州省贵阳郊区进行了水稻强化栽培体系 (SRI)试验 ,取得较好的效果。结果表明 :用 4 0 cm× 4 0 cm密度双株稀植 ,不同播种期产量分别为 5 5 5 .4 kg/ 6 6 7m2 和5 33.3kg/ 6 6 7m2 。The System of Rice Intensification(SRI) was experimented at the outskirt of Guiyang city ( with altitude of 1140 meters) in 2001. The high quality two line hybrid rice Liangyou 363 was tested with SRI technology in different sowing date and planting density. The results showed that higher yield ( 555.4 kg/667m 2 and 533.3kg/667m 2 to different sowing date of April 12 and April 28) under same planting density of 40cm× 40cm with two seedlings each pit.
