摘要
在扬两优6号水稻上，研究了拔节前10d喷施立丰灵对水稻抗倒伏性能及产量的影响。结果表明：喷施立丰灵600g／hm^2，可降低株高和缩短第1～5节的节间长度，促进幼穗发育，增加穗粒数和实粒数，最终提高产量。
The effects of lodging and yield of Lifengling sprayed on Yangliangyou No. 6 rice ten days before jointing were studied. The results indicated that 600 g/hm^2 Lifengling could decrease plant height, shorten section length, promote the panicle development, increase the grains per spike and filled grains, and increase the yield finally .
