摘　　要：2年超级杂交稻强化栽培体系 (SRI)试验产量平均在 10 .0t/hm2 以上 ,最高可达 12 .15t/hm2 ,增产效果明显 ;一般能节省用种量 1/2～ 2 /3 ,节水 1/2左右。在SRI条件下 ,增产效果 :品种 >密度 >每穴苗数。分蘖能力强 ,重穗型组合更能发挥其特点 ;多穗与大穗协调性好是高产的关键。该栽培体系在安徽省长江以北单季稻缺水地区有着更加广阔的应用前景。Two year's experiment in System of Rice Intensifying indicated that the efficiency of yield increment was significant, in which the average yield was over 10.0?t/hm2 and the highest yield was 12.15?t/hm2, and the quantity of seeding was decreased by 1/2 or 2/3, and the application amount of water was saved by 1/2 or so. The descending order, according to the efficiency of SRI in improving rice yield , was as follows: variety, culturing density and seedlings per hole. The variety used in SRI produced more tiller and high yield, which would exert the SRI's characteristics. The key of high yield of SRI was the harmony of more spike/per plant and heavier spike/per plant. There would be more splendid future in rice yield increment through the application of SRI in the water-lack areas.
