采用随机区组试验分析了绿荣追施宝对水稻品种305穗粒数、千粒质量和产量的影响,结果表明,北京昌平沙河松来堡试验基地喷施绿荣追施宝与清水对照和常规施肥相比,增产均显著,穗粒数分别平均增加5,6粒,千粒质量分别平均增加0.5,0.6 g,分别增产915,1 095 kg/hm2,增产率分别为15.6％和19.3％.海淀上庄长乐基地,喷施绿荣追施宝与清水对照和常规施肥相比,增产均达显著水平,穗粒数分别平均增加8,9粒,千粒质量分别平均增加0.5,0.7g,分别增产1 110,1 260 kg/hm2,增产率分别为12.6％和16.7％.%Randomized block experiments were carried out to study the effect of "Lyurong" plant growth regulator on grain number per spike, 1 000-grain weight and yield of rice 305. The results showed that "Lyurong" plant growth regulator had a mean increase of 5 and 6 grains per spike, 0.5 and 0.6 g 1 000-grain weight, 915 kg/hm2 and 1 095 kg/hm2, and improved rice yield by 15.6% and 19.3%, respectively. Compared with only spring pure water and applying fertilizer at Songlaibao village, Shahe town, Changping District, Beijing. And at Changle village, Shangzhuang town, Haidian District, Beijing, the "Lyurong" plant growth regulator enhanced averagely 8 and 9 per spike, 0.5, 0.7 g 1 000-grain weight, 1110 kg/hm2 and 1 260 kg/hm2 and increased rice yield by 18.6% and 16.7%, respectively.
