摘　　要：采用不同保水复合肥对草木樨的发芽率及促进生长的试验研究表明 :保水复合肥 1～ 4号对种子发芽及幼苗生长有促进作用。 1号、2号对种子发芽效果表现最佳 ,但 1号、2号对促进生长没有 3号、4号显著。 3、4号比 CK4的苗高分别增高 4 1 .1 6%、35 .97% ,比 CK4的发芽率分别提高 4 5 .5 7%、4 7.72 %。由此可知 ,3、4号对提高发芽率及促进生长都有显著作用。Based on experiments on effects of different waterretaining complex fertilizer on germination percentage and promotion of growth of Melilotus officinalis Desr., No.1 ~ 4 waterretaining complex fertilizer can promote the growth of seedlings. No.1 and No.2 waterretaining complex fertilizer can promote germination of seeds, but play less obvious role on growth of seedlings than No.3 and No. 4. No. 3 and No. 4 waterretaining complex fertilizer can improve germination percentage and promote growth of seedlings obviously.
