玉米喷洒金得乐生长调节剂增产效应的研究

Research on increasing effect by sprinkling growth adjusting agent Jindele of corn

通过对玉米不同生长期喷洒生长调节剂金得乐试验,结果得出:在玉米8展叶期喷洒金得乐450 mL/hm2兑水225 kg,可降低株高7.23%,降低穗位高17.37%,缩短茎基部节间长度,增粗茎杆,提高玉米抗倒力,提前成熟2 d,并对后期叶组茎节发育有一定促进作用,增产7.26%,效果最好.

To sprinkle growth adjusting agent Jindele during different periods of corn could get the result showed that during the 8 extending leaves period of corn sprinkling Jindele 450mL/hm2 plus water 225kg can lower the plant height 7.23%,height of ear of corn 17.37%,shorten the length among the bottom branches,enlarge the stem,raise the resistant force to lodging,ripen 2 days earlier and have some promoting action on the final-period growth groups of grains and leaves,stems and branches,increase production by 7.26%,The effect is the best.
