作底肥可将锌肥和有机肥、生理酸性化肥、细土混合使用。锌在土壤中移动能力差,应随耕地翻入土中。锌在土壤中肥效较长,可隔年施用。蘸根用氧化锌(0.1%~0.2%浓度)溶液蘸根,但蘸根时间不易过长,一般3分钟即可,时间过长会产生药害。浸种将硫酸锌配成0.02%~0.05%的溶液,种子和浸种液以1∶1为宜,浸6小时~12小时后捞出晾干(切忌在太阳光下曝晒,应阴干)。拌种以少量水溶解锌肥,再用清水稀释,拌种时以所有种子都沾上
For the base fertilizer can be zinc and organic fertilizer, physiological acid fertilizers, fine soil mixed use. Zinc poor mobility in the soil, with the farmland should turn into the soil. Zinc fertilizer in the soil longer, can be applied every other year. Dipping root with zinc oxide (0.1% ~ 0.2% concentration) solution dipped root, but the dipping time is not easy too long, usually 3 minutes, the time is too long will have injury. Soaking the seed soaking the solution of zinc sulfate into 0.02% ~ 0.05%, the seed and soaking solution to 1: 1 is appropriate, soaking for 6 hours to 12 hours after drying (avoid sun exposure, should be dry). Seed dressing with a small amount of water to dissolve the zinc fertilizer, then diluted with water, seed dressing all seeds stained
