摘要
锌是植物生长发育必需的微量元素之一。研究施用锌肥对玉米的增产效果,结果表明：底施锌肥后玉米的株高、穗数、千粒质量均有明显提高,增产效果明显,比对照增产54.7～105.9 kg/667 m2,增产率为7.2%～14.4%,其中以每667 m2施2 kg锌肥的增产效果为佳。
Zinc is one of the essential microelements for plant growth. To study yield increasing effect of maize by applying zinc fertiliz- er, the result shows that after bottom zinc fertilizer application, maize plant height, number of panicles and mass of 1000 grains in- creased obviously, the effect of yield increasing is obvious, yield increased 54.7-105.9 kg/667 m2 by contrast, increased rate is 7.2%- 14.4%, the optimal yield increasing method is every 667 m2 using 2 kg zinc fertilizer.
