摘  要:
对30、38 d两个秧龄水稻喷施立丰灵的效果进行了研究,结果表明:30 d秧龄大田植株喷施立丰灵后有重塑株型、基部节间明显地缩短和增粗,增强了基部强度和抗倒能力,达到抗倒增产目的;而38 d秧龄大田植株喷施立丰灵能有效控制老秧易抽长叶和盖顶致倒,还能促发分蘖,促进了部分中小分蘖成穗,增加有效穗和产量。可增产43.5~62.5 kg/667m2,增幅达8.1%~17.2%。

摘  要:
The effect of spraying Lifengling to rice with two seedling ages(30 d and 38 d) was studied.The results indicated that spraying Lifengling to rice plant with 30 d seedling age had effects of lodging resistance and yield increasing,which include remodeling plant shape,obvious shortening length of basal internodes and increasing basal diameter,enhancing basal intension and lodging resistance;spraying Lifengling to rice plant with 38 d seedling age can control old seedling giving birth to longer upper leaf and resulting in lodging,promoting part of middle and small tillering to panicle,also can increase rice available spike and enhancing yield by 652.5~937.5 kg/hm2 with amplitude of 8.1%~17.2%.
