摘　　要：专题攻关与综合试验研究结果表明 :巴西陆稻 IAPAR9在扬州丘陵地区有较好的适应性与丰产性。在播种期除补充必要的少量水外 ,可利用生长季自然水 ,达到单产 6750～ 750 0 kg/hm2 的生产潜力。试验研究还表明 ,适时早播、适当稀植促大穗。Comprehensive and special experiments on IAPAR9, a Brizal upland rice variety, were carried out in hill region of Yangzhou during 1998~1999. The results showed that IAPAR9 had good adaptabilityandproductivity. It could be rainfed except irrigating necessarily at sowing, and yield 6 750~7 500 kg/hm 2 grain. The key practices for high yield under wheat rice system should be sowing timely, promoting large spanicle by thin seedling, controlling weeds and rice borers.
