正确答案
①草坪养护:此时草坪已停止生长,进入休眠期,但在12月上旬土壤还未完全封冻,此时草根处在晚冻日化的交替时期,易使草根拉伤断裂,尤其是毛细根更为严重。对于绿地来说,主要作好冬灌工作,蔬根打孔,灌沙,施基肥。基肥主要以复合肥为主,有机无机结合使用。基肥施量0.1-0.15kg/㎡,以撒施为主,撒施后灌沙打孔浇水。②乔灌木养护:对于落叶乔木来说,此时已休眠,从12月中旬开始进行修剪,同时结合施肥,以穴施为主。对部分树种(易生地下害虫的树种,如月季)穴内施呋喃丹,施量20-25g/株。③补植苗木及草坪:对于因公共设施的建设及人为等原因造成的苗木草坪进行补栽,补栽后一周内每3天浇水一次,以后半月浇水一次,三次后可正常浇水。④冬季雨雪少,叶面灰尘多,要多进行叶面冲洗。
