| Abstract: | 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,1 110 kg/hm2 and 1 260 kg/hm2 and increased rice yield by 18.6% and 16.7%,respectively. |
