大量供應濕地松苗高度20厘米起,根系發達,成活率高,具體事宜,溝通聯系
濕地松(song) [松(song)科] [松(song)屬(shu)]
拉丁名(ming):Pinus elliottii
形態(tai)特征:
常綠(lv)大喬木,樹干通直,高30～36米(mi).樹皮灰(hui)褐色,縱裂呈(cheng)鱗(lin)狀塊(kuai)片剝落.冬芽圓柱狀,紅褐色,粗壯,無(wu)樹脂.針葉(xie)二針或三(san)針一束,長18～30厘米(mi),深綠(lv)色,腹背兩面均有氣孔線,邊緣(yuan)有細(xi)鋸齒(chi).3～4月(yue)開花.翌年10～11月(yue)果熟,球(qiu)果長圓錐形,2～3個聚生.種子卵圓,具(ju)三(san)棱.
生長習性(xing):
喜(xi)光(guang),忌蔭蔽.耐寒,又能(neng)抗高溫.耐旱亦耐水濕,可忍耐短(duan)期淹水,故名.根(gen)系(xi)發達(da),抗風力(li)強(qiang).喜(xi)深厚肥沃的中性至強(qiang)酸性土壤(rang),在堿(jian)土中種植有黃化現(xian)象.
濕地松蒼(cang)勁而(er)速(su)生,適應性強,材質好,松脂產量高(gao).中國已引種(zhong)(zhong)馴化成(cheng)功達數十(shi)年,故在(zai)長江(jiang)以(yi)南的園林和自(zi)然風(feng)景區中作(zuo)(zuo)為(wei)重要樹(shu)種(zhong)(zhong)應用,是很有發(fa)展前途的.可作(zuo)(zuo)庭園樹(shu)或(huo)叢(cong)植(zhi)(zhi)、群植(zhi)(zhi),宜植(zhi)(zhi)于河岸池邊.
繁殖培育:
用(yong)播種(zhong)繁殖(zhi).種(zhong)子應選自適(shi)當類(lei)型的(de)優(you)良母株,暴曬2～3天后,去(qu)翅(chi)凈(jing)種(zhong),再稍(shao)日(ri)曬,使含水率不高于12%,置于密封容器中,在室溫下可(ke)保(bao)存(cun)半年(nian)多.如將種(zhong)子含水率降至9%,貯于5℃以下低溫處(chu),則可(ke)保(bao)存(cun)發芽力達(da)數年(nian)之久.在播種(zhong)前,先(xian)用(yong)福(fu)爾(er)馬林～2%溶液浸種(zhong)消毒20分(fen)鐘,再用(yong)清水洗凈(jing)后,用(yong)55～60℃溫水浸種(zhong),令其(qi)自然冷(leng)卻,經一(yi)晝夜后取出播種(zhong).
濕地松還可用(yong)扦插(cha)發(fa)育苗,6月(yue)上旬(xun)或10月(yue)中下旬(xun),從1～2年苗木上剪取側(ce)枝扦插(cha),成(cheng)活率可達80%以(yi)上.
在園林中(zhong)行(xing)獨(du)植(zhi)(zhi)或叢(cong)植(zhi)(zhi)時(shi),可用3～5年(nian)生(sheng)大苗(miao),行(xing)帶土團(tuan)定(ding)植(zhi)(zhi).但(dan)在育(yu)苗(miao)期(qi)間應經1～3次(ci)移栽(zai).
苗(miao)期的病(bing)蟲(chong)害(hai),主要有(you)(you)松(song)(song)(song)苗(miao)立枯病(bing)、大蟋(xi)蟀等.定植后則有(you)(you)松(song)(song)(song)梢螟、日本松(song)(song)(song)葉(xie)(xie)蜂等為害(hai).松(song)(song)(song)毛蟲(chong)也(ye)吃濕地松(song)(song)(song)的針(zhen)葉(xie)(xie),但(dan)更(geng)喜吃馬尾松(song)(song)(song)葉(xie)(xie),故受害(hai)較少.
