                荊門報發表於2015年03月12日23:59:22 | 養花草樹 | 標簽(tags):樹苗 挑選

                植樹的方法和後期養護固然重要,但樹苗的甄選也不可忽視。在此,市園林局提供了關於以下三種我市城區常見的植★物的挑選方法做了簡單介紹,以方便市民自己購買樹苗。

                喬木(如欒樹、紅葉意楊等):樹幹挺直,不應有〒明顯彎曲,小彎曲也不得超出兩處,無蛀幹害蟲和未愈合的機械損〓傷。分枝點高度2.5m-2.8m。樹冠豐滿,枝條分布均勻、無嚴重病畢竟以千仞峰蟲危害,常綠樹隨後低笑道葉色正常。根系發育良好、無嚴重病蟲危害,移植時根系或土球↑大小,應為苗木胸徑的8-10倍。

                灌木(如紫薇、紫荊等):根系發達,生長茁壯,無嚴重病蟲危害,灌叢勻稱,枝條分布合理,高度不得低於1.5m,叢生灌木枝條至少在4-5根以上,有主幹的灌木主幹氣勢又強了不少應明顯。

                綠籬苗(如金銀花、紅帽月季、薔薇等):針葉常綠樹苗高度不得低於1.2m,闊葉常【綠苗不得低於50cm,苗木應◤樹型豐滿,枝葉茂密,發育正常,根系發達,無嚴重病蟲危害。
