2、养护管理樱花的栽培技术,养护管理--樱花是落叶乔木,性喜阳、耐寒、耐旱,忌盐碱,适宜在疏松肥沃、排水良好的地块生长,花期怕风,萌蘖力强且生长迅速。 一、土壤要求及改良措施 樱花在含腐殖质较多的沙质壤土和粘质壤土中(pH5.5至6.5)都能很好地生长。在南方土壤粘重的地方,一般混合自制腐叶土(收集树叶及酸性土、鸡粪、木炭粉沤制而成的土壤)。注意,混合前必须将原有粘土块全部打碎,否则起不到改土作用。 在地下水位不足1米的地方采用高栽法,即把整个栽植穴垫平后,再在上面堆土栽苗。北方碱
3、性土,需要施硫磺粉或硫酸亚铁等调节pH值至6左右。每平方米施硫磺粉2克,有效期1至2年,同时每年测定,使pH值不超过7。 山樱、染井吉野等品种树干通直,树体较大,是强阳性树种,要求避风向阳,通风透光。成片栽植时,要使每株树都能接受到阳光。 二、栽植措施 定植时间在早春土壤解冻后立即栽植,一般为二三月份。 栽植方法 栽植前仔细整地。在平地栽植可挖直径1米,深0.8米的穴。穴内先填约一半深的改良土壤,把苗放入穴中央,使苗根向四方伸展。少量填土后,微向上提苗,使根系充分伸展,再行轻踩。栽苗深
4、度要使最上层的苗根距地面5厘米。栽好后做一积水窝,并充分灌水,最后用跟苗差不多高的竹片支撑,以防刮风吹倒。 strengthenthesenseofresponsibility,worktosolvethelackofdecentoccupationexplainaway,conductproblems.Toestablishtheoverallconcept,eliminatedepartmentalism.Strictassessmentandaccountability,tosolvethespirit
