水杉树虽然可以通过播种和扦插两种方式繁殖,不过因为水杉树的苗木价格本身并不昂贵,而且扦插繁殖的成活率又比较高,所以这里比较推荐用扦插的方式进行水杉树的栽种。 一、水杉树的栽种养殖方法 习性:水杉性喜阳光,较耐寒,不耐阴。适应性强,在土层深厚肥沃,湿润的酸性土壤中生长最好,能耐46℃高温及-30℃严寒,不耐干旱瘠薄,也怕水涝。 繁殖:播种和扦插繁殖。水杉25龄以下结籽甚少,25~30年开始结籽,40~60年进入盛期。播种应在春季地温在12℃以上时为宜。播后盖草保湿。扦插繁殖硬枝和嫩枝均可,春季扦插插穗用1年生苗的截干萌条及侧枝为宜,在发芽前进行。嫩枝扦插在6月至7月份进行,插穗选自1~5年生实生苗上剪取的1年生充实健壮的枝条。扦插地经常保持湿润通风,可促进早日生根。 整地:要求同常规小粒种子育苗。床宽100cm,高20cm,整平后稍加镇压,每平方米撒施喃喃丹农药3g,防治地下害虫及蚯蚓。育苗用苗床2月中旬前准备好,每500g种子,播于20m2苗床中,将来可供大田移植用。大田移植苗床3月下旬前准备好。 移苗:3月下旬或4月初,幼苗长有2-3对真叶时,经过几天的炼苗后,用小铁撬慢慢撬起幼苗,并尽可能基部带一小块土壤,尽量不伤根伤叶,进行逐株移栽,株行距20cm×25cm,每平方米可栽12-18株,须在4月上旬完成。以后气温不断增高,蒸发量加大,不利成活,故不能移栽。一般每人每可称栽1500株,边撬苗,边移栽,及时浇透定根水,成活率可达90%以上。其它管理措施同常规育苗。 病害:立枯病是水杉苗期的主要大害。当种壳顶出土面时,即用800-1000倍的50%多菌灵药液喷洒整个床面,使幼苗经过一次药浴,既防病,又补给水份,一举二得。当真叶长出后如同上法再喷洒一次,可在幼苗期起到预防和控制立枯病的危害。 二、2015年水杉价格参考表 水杉小苗( 高度40CM 地径0.4CM 0.16元/棵)--利川市丰林种苗专业合作社 水杉( 米径10CM 170元/棵)--沭阳万泰苗木场 水杉( 米径4CM 22元/棵)--句容市茅山镇永兴万氏苗圃场 水杉( 米径8CM 160元/棵)--河南潢川原生态苗圃场 水杉种子( 100元/棵)--华涛园艺场 水杉小苗( 高度80CM 0.45元/棵)--华涛园艺场 水杉( 米径5-15CM 电议元/棵)--上海才元苗木批发 水杉( 米径6CM 高度300CM 冠幅150CM 80元/棵)--湖南常源苗木基地 水杉( 米径3-15CM 面议元/棵)--苗木专供 水杉( 米径9CM 120元/棵)--沭阳万泰苗木场 水杉( 米径15CM 580元/棵)--沭阳万泰苗木场 水杉( 米径10CM 160元/棵)--南京华明雪松园林场 三、水杉树的园林应用 水杉树干通直挺拔,树形壮丽,叶色翠绿,入秋变为黄色,是著名的庭园观赏树。可于公园、庭园、草坪、绿地中孤植、列植或群植。也可成片栽植营造风景林,并配置常绿地被植物,还可栽于建筑物用作行道树,效果均佳,水杉对二氧化硫有一定的抗性,是工矿绿化的好树种。
