將一水硫酸鋅配成0.02%～0.05%的溶(rong)(rong)(rong)(rong)液(ye)，將種(zhong)(zhong)(zhong)子(zi)(zi)倒入溶(rong)(rong)(rong)(rong)液(ye)中(zhong)(zhong)，溶(rong)(rong)(rong)(rong)液(ye)以淹沒(mei)種(zhong)(zhong)(zhong)子(zi)(zi)為度。水稻用(yong)0.1%的硫酸鋅溶(rong)(rong)(rong)(rong)液(ye)，先將稻種(zhong)(zhong)(zhong)用(yong)清水浸(jin)(jin)泡1小(xiao)時(shi)，再(zai)放入硫酸鋅溶(rong)(rong)(rong)(rong)液(ye)中(zhong)(zhong)，早、中(zhong)(zhong)稻種(zhong)(zhong)(zhong)子(zi)(zi)浸(jin)(jin)48小(xiao)時(shi)，晚稻種(zhong)(zhong)(zhong)子(zi)(zi)浸(jin)(jin)24小(xiao)時(shi)。玉米種(zhong)(zhong)(zhong)子(zi)(zi)用(yong)0.02%～0.05%的硫酸鋅溶(rong)(rong)(rong)(rong)液(ye)浸(jin)(jin)6～8小(xiao)時(shi)，撈出后(hou)即(ji)可播種(zhong)(zhong)(zhong)。小(xiao)麥種(zhong)(zhong)(zhong)子(zi)(zi)用(yong)0.05%的硫酸鋅溶(rong)(rong)(rong)(rong)液(ye)浸(jin)(jin)12小(xiao)時(shi)，撈出后(hou)即(ji)可播種(zhong)(zhong)(zhong)，要求播種(zhong)(zhong)(zhong)地墑情好，否(fou)則播種(zhong)(zhong)(zhong)后(hou)種(zhong)(zhong)(zhong)子(zi)(zi)失水影響出苗。

每千克種子用硫酸鋅2～3克，以少量水溶解后噴于種子上，邊噴邊攪拌，用水量以能拌勻種子為宜，種子陰干后即可播種。用作蔬菜拌種、包衣、浸種和蘸根等方面，必然要事前做應用濃度試驗，省得濃度不適宜傷苗。播種玉米時用硫酸鋅做拌種肥，把磷肥摻在田舍肥中做底肥施入，防止鋅肥與磷肥接觸。

普通缺鋅田，泥土有效鋅含量為0.5～0.7毫克/千克，每畝用硫酸鋅200～300克，加干細土和必然量的水配成0.5%～2.0%的硫酸鋅泥漿，將水稻秧苗浸入泥漿中5～10秒，取出后隨即插秧。
