A stady on the effects of zine ferfilizer on the gronth anddevelopmentof maize was Conduted in Tongliao Region,Theresults showed that foliagespraying of zine on maize crop could conpensate the soil zine deficiency inTonglian Region,and thus,provide a banlanced hufrition level for maizegronth and development.Zine sprayed maize crop showed a high growthvig-ority,strong stalk,big corn and high Yielof.
