不同生长调节剂拌种对小麦生长发育及产量的影响

Effect of Seed-dressing with Plant Growth Regulator on Wheat Development and Yield

小麦播前用 399调节剂拌种后具有明显的促根 (0 .4～ 3.5条 /株 )、促蘖 (0 .9～ 1.1个 /株 )、增穗 (2 8.0万 /hm2 )、增粒 (0 .3粒 /穗 )作用 ,增产 70 2 .9kg/hm2 ,增产效果显著。小麦拌种剂和麦业丰拌种能有效降低株高 。

Seed dressing with 399 before sowing could remarkably increase the number of secondary roots, tillers, spikes and grains per spike. The yield could also increase by 702.9 kg/hm 2. The seed dressing agent Changquan and Maiyefeng could shorten the plant height and increase the resistance to lodging of wheat.
