Study on Effects of Adding Trace Elements under the Same Amount of Fertilizer

[Objective]The aim was to increase production levels of low-yielding fields in Xingguo County,and clear application results of trace elements for increasing rice yield.[Method] The effect of trace elements on production levels of early rice yield was getting,by applying silicon,zinc,sulfur,fertilizer at different grow periods of rice.[Result] Increasing single trace elements on early rice could achieve better output growth.Adding zinc fertilizer could increase grain plumpness of late rice,and adding silicon fertilizer could promote strong and inprove rod disease resistance,and adding sulfur fertilizer could promote tillering.[Conclusion] The results provided technical references for rice production.
