桉(an)樹(shu)(shu)是一種(zhong)(zhong)(zhong)速生樹(shu)(shu)種(zhong)(zhong)(zhong)，抗逆性強，種(zhong)(zhong)(zhong)植(zhi)(zhi)(zhi)面積廣。在桉(an)樹(shu)(shu)種(zhong)(zhong)(zhong)植(zhi)(zhi)(zhi)之(zhi)中，由(you)于種(zhong)(zhong)(zhong)植(zhi)(zhi)(zhi)技術(shu)的(de)(de)影響，對桉(an)樹(shu)(shu)的(de)(de)種(zhong)(zhong)(zhong)植(zhi)(zhi)(zhi)影響很大。為了(le)更好(hao)地(di)提高桉(an)樹(shu)(shu)的(de)(de)種(zhong)(zhong)(zhong)植(zhi)(zhi)(zhi)質量，有必要不(bu)斷加強桉(an)樹(shu)(shu)的(de)(de)種(zhong)(zhong)(zhong)植(zhi)(zhi)(zhi)技術(shu)，從而(er)更好(hao)地(di)提高桉(an)樹(shu)(shu)種(zhong)(zhong)(zhong)植(zhi)(zhi)(zhi)的(de)(de)經(jing)濟效益。

桉(an)樹(shu)(shu)(shu)(shu)是常綠高(gao)大(da)樹(shu)(shu)(shu)(shu)種(zhong)(zhong)，共有600株。其余種(zhong)(zhong)類多見(jian)于(yu)(yu)山川平(ping)原(yuan)等陽光充(chong)足的(de)(de)地(di)區，廣泛(fan)種(zhong)(zhong)植(zhi)于(yu)(yu)中國東南和華南地(di)區。桉(an)樹(shu)(shu)(shu)(shu)樹(shu)(shu)(shu)(shu)冠較小(xiao)(xiao)，蒸騰作用(yong)較小(xiao)(xiao)，透光率(lv)較高(gao)。由于(yu)(yu)桉(an)樹(shu)(shu)(shu)(shu)是一種(zhong)(zhong)節水(shui)(shui)型樹(shu)(shu)(shu)(shu)種(zhong)(zhong)，不需要經常澆水(shui)(shui)，桉(an)樹(shu)(shu)(shu)(shu)更適(shi)合在(zai)(zai)酸性土壤(rang)（如黃壤(rang)、紅壤(rang)）之上(shang)生長。適(shi)宜(yi)在(zai)(zai)排水(shui)(shui)良好、土壤(rang)疏松、土層較深的(de)(de)地(di)區種(zhong)(zhong)植(zhi)。我國廣東、廣西、海(hai)南等地(di)屬亞(ya)熱(re)(re)帶(dai)、熱(re)(re)帶(dai)氣候，常年光照充(chong)足，水(shui)(shui)、光、熱(re)(re)條件最(zui)接近桉(an)樹(shu)(shu)(shu)(shu)生長特性，年降(jiang)水(shui)(shui)量高(gao)出150%，是目前(qian)我國最(zui)適(shi)宜(yi)種(zhong)(zhong)植(zhi)桉(an)樹(shu)(shu)(shu)(shu)的(de)(de)地(di)方。因(yin)為桉(an)樹(shu)(shu)(shu)(shu)是一種(zhong)(zhong)耐寒耐高(gao)溫的(de)(de)樹(shu)(shu)(shu)(shu)種(zhong)(zhong)。桉(an)樹(shu)(shu)(shu)(shu)一般(ban)選擇在(zai)(zai)土壤(rang)肥力高(gao)、排水(shui)(shui)良好的(de)(de)山地(di)、丘陵或丘陵地(di)區種(zhong)(zhong)植(zhi)。由于(yu)(yu)桉(an)樹(shu)(shu)(shu)(shu)對低溫非常敏(min)感，所以在(zai)(zai)選址時要特別注意5度。

一(yi)般來(lai)說，桉(an)樹(shu)種(zhong)植用(yong)地(di)選(xuan)擇之后(hou)，種(zhong)植后(hou)要(yao)徹底清理干凈。目的(de)是清除土壤(rang)之中(zhong)(zhong)的(de)雜草和(he)其他植物(wu)，防止(zhi)殘(can)留植被吸(xi)收養(yang)分(fen)，影響(xiang)桉(an)樹(shu)的(de)生(sheng)長。這在人(ren)工(gong)(gong)(gong)種(zhong)植之中(zhong)(zhong)尤為(wei)重(zhong)要(yao)，為(wei)了(le)營(ying)造良(liang)好的(de)桉(an)樹(shu)生(sheng)長環(huan)境(jing)，最重(zhong)要(yao)的(de)一(yi)步就是消滅白蟻的(de)天敵。白蟻不僅危(wei)害(hai)桉(an)樹(shu)，而(er)且(qie)還會危(wei)害(hai)其他樹(shu)木。因此，這已成為(wei)一(yi)種(zhong)管理方法。樹(shu)上的(de)工(gong)(gong)(gong)作人(ren)員經常(chang)(chang)要(yao)完成一(yi)項任務。這項工(gong)(gong)(gong)作的(de)要(yao)求不僅要(yao)經常(chang)(chang)重(zhong)復，而(er)且(qie)要(yao)小心(xin)。桉(an)樹(shu)種(zhong)植用(yong)地(di)規(gui)劃本工(gong)(gong)(gong)作的(de)實(shi)質(zhi)是合理劃分(fen)選(xuan)擇的(de)土地(di)和(he)種(zhong)植桉(an)樹(shu)。因為(wei)是人(ren)工(gong)(gong)(gong)種(zhong)植，不能(neng)(neng)像(xiang)野生(sheng)植物(wu)一(yi)樣留給(gei)野生(sheng)植物(wu)，但必須精心(xin)規(gui)劃，才(cai)能(neng)(neng)有(you)計劃地(di)進行。它將(jiang)給(gei)當地(di)的(de)生(sheng)長環(huan)境(jing)帶來(lai)良(liang)好的(de)循環(huan)。

合(he)理的(de)(de)種(zhong)植(zhi)(zhi)密(mi)度是(shi)保證(zheng)桉樹效(xiao)益最大(da)(da)化的(de)(de)關(guan)鍵。苗木的(de)(de)初植(zhi)(zhi)、定植(zhi)(zhi)、管理等(deng)各因素應充分(fen)考慮(lv)自然災害的(de)(de)發生(sheng)、發生(sheng)、管理等(deng)因素。如果經營目(mu)(mu)標是(shi)種(zhong)植(zhi)(zhi)刨花(hua)板加工的(de)(de)大(da)(da)直徑木材，密(mi)度通常為100株畝(mu)（1.5-2.0）MX（3.0?4.0）m；如果經營目(mu)(mu)標是(shi)種(zhong)植(zhi)(zhi)用于切片、造紙等(deng)目(mu)(mu)的(de)(de)的(de)(de)小(xiao)直徑木材，則適合(he)集約種(zhong)植(zhi)(zhi)，密(mi)度130-150英寸(cun)畝(mu)，行距（1.5-2.0）MX（2.0-2.5）M.

桉(an)樹(shu)(shu)種(zhong)植(zhi)過程之(zhi)(zhi)(zhi)中的(de)(de)造林，植(zhi)樹(shu)(shu)造林也是一項更重要(yao)的(de)(de)任務(wu)，工作(zuo)人員要(yao)科學安排(pai)播(bo)種(zhong)時間，一般控制在每年2月(yue)至(zhi)4月(yue)。種(zhong)植(zhi)工作(zuo)應(ying)(ying)(ying)在雨(yu)(yu)天(tian)進行，保證土(tu)壤水(shui)分能滿足桉(an)樹(shu)(shu)苗(miao)木(mu)生長需要(yao)，提高桉(an)樹(shu)(shu)在種(zhong)植(zhi)過程之(zhi)(zhi)(zhi)中的(de)(de)成(cheng)活率(lv)。移栽(zai)過程之(zhi)(zhi)(zhi)中還應(ying)(ying)(ying)注意天(tian)氣變化，避免晴(qing)天(tian)移栽(zai)。同時，桉(an)樹(shu)(shu)移栽(zai)之(zhi)(zhi)(zhi)后(hou)應(ying)(ying)(ying)采用回(hui)填土(tu)追(zhui)肥，研(yan)究(jiu)桉(an)樹(shu)(shu)不同生長階段所(suo)需各(ge)種(zhong)肥料的(de)(de)用量(liang)和(he)比(bi)例，并(bing)(bing)及(ji)時施肥。追(zhui)肥的(de)(de)最佳時間是雨(yu)(yu)之(zhi)(zhi)(zhi)后(hou)，由于(yu)雨(yu)(yu)后(hou)土(tu)壤疏松(song)濕潤，有利于(yu)肥料吸收，應(ying)(ying)(ying)均勻分布，不集中在一處，并(bing)(bing)用土(tu)覆(fu)蓋(gai)；追(zhui)肥的(de)(de)量(liang)和(he)具體種(zhong)類視情況而(er)定；追(zhui)肥后(hou)應(ying)(ying)(ying)清除雜草，以防追(zhui)肥與桉(an)樹(shu)(shu)爭奪肥料。

草(cao)木(mu)(mu)生(sheng)(sheng)長一般(ban)很茂盛。因(yin)此，如果不及(ji)時(shi)除草(cao)，會產(chan)生(sheng)(sheng)林(lin)(lin)木(mu)(mu)肥料(liao)，因(yin)此，為了節約(yue)成(cheng)本，節約(yue)水土(tu)，一般(ban)選(xuan)擇以桉(an)(an)樹為中(zhong)心的(de)輻(fu)射除草(cao)。桉(an)(an)樹的(de)主要病(bing)害(hai)(hai)有青枯病(bing)、焦枯病(bing)和(he)(he)紅葉(xie)枯病(bing)。主要害(hai)(hai)蟲(chong)(chong)為白蟻、小田虎和(he)(he)桉(an)(an)樹卷葉(xie)蛾。加強林(lin)(lin)地管理，減少(shao)林(lin)(lin)地生(sheng)(sheng)態環境，加強檢疫(yi)，防止病(bing)蟲(chong)(chong)害(hai)(hai)蔓延桉(an)(an)樹病(bing)蟲(chong)(chong)害(hai)(hai)研究(jiu)，了解其特(te)點(dian)，及(ji)時(shi)發現和(he)(he)消滅；做好(hao)病(bing)蟲(chong)(chong)害(hai)(hai)監測(ce)預報，掌(zhang)握病(bing)蟲(chong)(chong)害(hai)(hai)發展特(te)點(dian)和(he)(he)動態，開展有針對性的(de)防治。

在桉樹(shu)種(zhong)植過程之中(zhong)，積極有效地管理(li)桉樹(shu)，因此(ci)，在新時期(qi)桉樹(shu)種(zhong)植技術研究過程之中(zhong)，為了營造(zao)良好的桉樹(shu)生長(chang)環境(jing)，提高(gao)桉樹(shu)種(zhong)植管理(li)的有效性，需要進行更深入的探索。
