欒樹(shu)主要用(yong)(yong)播種(zhong)(zhong)(zhong)法繁(fan)殖，分蘗，根插也可(ke)(ke)。種(zhong)(zhong)(zhong)子(zi)(zi)(zi)一般9～10月成熟，采(cai)種(zhong)(zhong)(zhong)要掌握好(hao)時機(ji)，采(cai)的(de)(de)過(guo)早，種(zhong)(zhong)(zhong)子(zi)(zi)(zi)發(fa)芽(ya)率低，過(guo)晚(wan)種(zhong)(zhong)(zhong)子(zi)(zi)(zi)已經脫(tuo)落，不(bu)易采(cai)集。采(cai)回的(de)(de)果實經晾曬(shai)后(hou)，除去膜質果殼等雜物(wu)即可(ke)(ke)獲得(de)純凈的(de)(de)種(zhong)(zhong)(zhong)子(zi)(zi)(zi)，種(zhong)(zhong)(zhong)子(zi)(zi)(zi)黑(hei)色(se)，圓(yuan)球形，徑(jing)約(yue)0.6cm，出(chu)種(zhong)(zhong)(zhong)率約(yue)20%，千(qian)粒重150g左右(you)，發(fa)芽(ya)率60%～80%。將(jiang)(jiang)種(zhong)(zhong)(zhong)子(zi)(zi)(zi)沙(sha)(sha)藏至(zhi)翌(yi)年春(chun)播。種(zhong)(zhong)(zhong)子(zi)(zi)(zi)有隔年發(fa)芽(ya)的(de)(de)習性。因種(zhong)(zhong)(zhong)皮堅硬不(bu)易透水(shui)(shui)，如不(bu)經處理(li)第2年春(chun)播，常不(bu)發(fa)芽(ya)或發(fa)芽(ya)率低。故最(zui)好(hao)當年秋季播種(zhong)(zhong)(zhong)，經過(guo)1冬(dong)(dong)后(hou)第2年春(chun)天發(fa)芽(ya)整齊。也可(ke)(ke)用(yong)(yong)濕沙(sha)(sha)層(ceng)積埋(mai)藏越冬(dong)(dong)，在(zai)晚(wan)秋選擇地勢干(gan)燥(zao)，排水(shui)(shui)良好(hao)，背風向陽(yang)處挖坑(keng)。坑(keng)寬1～1.5m，深在(zai)地下(xia)水(shui)(shui)位之上(shang)，凍(dong)層(ceng)之下(xia)，大約(yue)1m，坑(keng)長視種(zhong)(zhong)(zhong)子(zi)(zi)(zi)數量(liang)而定。坑(keng)底可(ke)(ke)鋪土層(ceng)石礫或粗(cu)砂，約(yue)10～20cm厚，坑(keng)中(zhong)插1束草把，以便通氣(qi)。將(jiang)(jiang)消(xiao)毒后(hou)的(de)(de)種(zhong)(zhong)(zhong)子(zi)(zi)(zi)與(yu)濕沙(sha)(sha)混合，放(fang)入坑(keng)內，種(zhong)(zhong)(zhong)子(zi)(zi)(zi)和(he)沙(sha)(sha)體積比為1∶3～1∶5，或1層(ceng)種(zhong)(zhong)(zhong)子(zi)(zi)(zi)1層(ceng)沙(sha)(sha)交錯層(ceng)積。每層(ceng)厚度約(yue)為5cm左右(you)。沙(sha)(sha)子(zi)(zi)(zi)濕度用(yong)(yong)手握成團，不(bu)出(chu)水(shui)(shui)，松(song)手觸之即散開為宜。裝到離地面20cm左右(you)為止(zhi)，上(shang)覆(fu)5cm河沙(sha)(sha)和(he)10～20cm厚的(de)(de)秸桿等，四周(zhou)挖好(hao)排水(shui)(shui)溝。來年3月取出(chu)種(zhong)(zhong)(zhong)子(zi)(zi)(zi)直接播種(zhong)(zhong)(zhong)。干(gan)藏的(de)(de)種(zhong)(zhong)(zhong)子(zi)(zi)(zi)播種(zhong)(zhong)(zhong)前40天左右(you)，用(yong)(yong)80℃的(de)(de)溫水(shui)(shui)浸種(zhong)(zhong)(zhong)后(hou)混濕沙(sha)(sha)催芽(ya)，當裂嘴種(zhong)(zhong)(zhong)子(zi)(zi)(zi)數達30%以上(shang)時即可(ke)(ke)條播，播種(zhong)(zhong)(zhong)深度2cm，行距(ju)25cm，每畝(mu)播種(zhong)(zhong)(zhong)量(liang)為4～5kg，覆(fu)土2～3cm。 

種子發(fa)芽出土后(hou)，要加(jia)強養(yang)護，苗(miao)(miao)(miao)(miao)高5～10（2m時，間苗(miao)(miao)(miao)(miao)1次，以每10平(ping)方米(mi)留(liu)苗(miao)(miao)(miao)(miao)100株為宜，要注(zhu)意(yi)中(zhong)耕除(chu)草，適時追肥，促使(shi)苗(miao)(miao)(miao)(miao)木(mu)(mu)旺盛(sheng)生(sheng)(sheng)長(chang)，秋季(ji)苗(miao)(miao)(miao)(miao)木(mu)(mu)落(luo)葉后(hou)即(ji)可掘(jue)起入(ru)溝(gou)假植(zhi)，翌年(nian)春季(ji)分(fen)栽。由(you)于欒(luan)樹樹干(gan)往往不易長(chang)直(zhi)，分(fen)栽后(hou)可采(cai)用(yong)適當密(mi)植(zhi)或平(ping)茬養(yang)干(gan)的(de)(de)方法(fa)養(yang)直(zhi)苗(miao)(miao)(miao)(miao)干(gan)。1年(nian)生(sheng)(sheng)苗(miao)(miao)(miao)(miao)高可達80～100cm。苗(miao)(miao)(miao)(miao)木(mu)(mu)在苗(miao)(miao)(miao)(miao)圃中(zhong)一般要經2～3次移植(zhi)，每次移植(zhi)時適當剪(jian)短主(zhu)根及(ji)粗(cu)側(ce)根，這樣可促進多發(fa)須根，使(shi)以后(hou)定植(zhi)容易成(cheng)活。欒(luan)樹適應性強，對干(gan)旱、水濕(shi)及(ji)風雪都有一定的(de)(de)抵(di)抗能力(li)。栽后(hou)管理工作較為簡單(dan)。樹冠具有自然整枝性能，不必多加(jia)修剪(jian)，任其自然生(sheng)(sheng)長(chang)。僅與秋后(hou)將枯、病枝及(ji)干(gan)枯果穗剪(jian)除(chu)即(ji)可，蟲害有大(da)蓑蛾、刺蛾和天牛等，較少發(fa)生(sheng)(sheng)。 

欒(luan)樹樹冠圓球形或傘形，適(shi)于(yu)庭園中(zhong)、池畔及(ji)路旁或草地中(zhong)栽(zai)植，也(ye)可(ke)用作(zuo)防(fang)護林，水土保持及(ji)荒山樹種(zhong)。種(zhong)子含油，可(ke)制(zhi)潤滑油及(ji)肥皂，花可(ke)供藥(yao)用及(ji)黃色染料。葉可(ke)作(zuo)染料，木材較脆，適(shi)做家具、器具等。
