1.由于树木根群分布广,吸收养料和水分全在须根部位,因此,施肥要在要根部的四周,不要靠近树干。
2.根系强大,分布较深远的树木,施肥宜深,范围宜大,如油松、银杏、臭椿、合欢等;根系浅的树木施肥宜较浅,范围宜小,如法桐、紫穗槐及花灌木等。
3.有机肥料要充足发酵、腐熟,切忌用生粪,且浓度宜稀,化肥必须完全粉碎成粉状,不宜成块施用。
4.施肥后(尤其是追化肥),必须及时适量灌水,使肥料渗入土内。
5.应选天气晴朗、土壤干燥时施肥。阴雨天由于树根吸收水分慢,不但养分不易吸收,而肥分还会被雨水冲失,造成浪费。
6.沙地、坡地、岩石易造成养分流失,施肥要深些。
7.氮肥在土壤中移动性较强,所以浅施渗透到根系分布层内,被树木吸收;钾肥的移动性较差,磷肥的移动性更差,宜深施至根系分布最多处。
8.基肥因发挥肥效较慢应深施,追肥肥效较快,则宜浅施,供树木及时吸收。
9.叶面喷肥是通过气孔和角质层进入叶片,而后运送到各个器官,一般幼叶较老叶,叶背较叶面吸水快,吸收率也高。所以实际喷布时一定要把叶背喷匀,喷到,使之有利于树干吸收。
10.叶面喷肥要严格掌握浓度,以免烧伤叶片,最好在阴天或上午10时以前和下午4时以后喷施,以免气温高,溶液很快浓缩,影响喷肥或导致药害。
11.城镇园林绿化地施肥,在选择肥料种类和施肥方法时,应考虑到不影响市容卫生,散发臭味的肥料不宜施用。
园林绿化中种植的都是有生命的植物,在园林绿化时,不仅要规划设计高标准,也要保证施工养护高水平,实现园林景观四季常绿,好景常在。
