一、選地整地

選(xuan)擇陽光充足(zu)、土(tu)(tu)(tu)(tu)層深厚、排(pai)水良好的砂質(zhi)壤(rang)土(tu)(tu)(tu)(tu)地(di)塊。選(xuan)地(di)后,每畝施土(tu)(tu)(tu)(tu)雜肥或圈肥,加過磷(lin)酸(suan)鈣和餅肥各50kg或磷(lin)酸(suan)二銨15kg,勻撒(sa)于地(di)內,深耕土(tu)(tu)(tu)(tu)壤(rang)35cm,整平耙(pa)細,做1m寬平畦,長短以地(di)形而定(ding)。

二、繁殖方式

(一)采(cai)用(yong)種子(zi)繁(fan)殖:生(sheng)長期2年。

生產中一(yi)般采用直播(bo)。桔(jie)梗種子細小,千粒重1.5g,發芽率(lv)85%,在溫度18~25℃、濕度足夠的情況下,播(bo)后(hou)10~15天出(chu)苗(miao)。

冬(dong)播(bo)或(huo)春(chun)(chun)(chun)播(bo):冬(dong)播(bo)于11月份(fen)~次(ci)年1月份(fen),春(chun)(chun)(chun)播(bo)于3~4月份(fen)。以(yi)冬(dong)播(bo)為好,一(yi)般采用(yong)(yong)(yong)撒播(bo)。播(bo)時(shi)將種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)用(yong)(yong)(yong)潮細沙土拌勻(比例為1盆土拌0.3kg種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi))撒于畦面上,用(yong)(yong)(yong)掃帚輕掃一(yi)遍,以(yi)不見(jian)種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)為度(即在(zai)土壤覆土厚度約2.5~3毫(hao)米(mi)),稍作震(zhen)壓(ya)。翌年春(chun)(chun)(chun),出(chu)苗早齊。春(chun)(chun)(chun)播(bo),要(yao)使(shi)出(chu)苗整(zheng)齊,必須進(jin)行種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)處理(li),或(huo)播(bo)后(hou)蓋草保濕(shi)(處理(li)方(fang)法:將種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)置于30℃溫水(shui)中浸泡,浸泡8小時(shi)撈出(chu),用(yong)(yong)(yong)濕(shi)布(bu)包上,放在(zai)25~30℃的(de)地(di)方(fang),上用(yong)(yong)(yong)濕(shi)麻(ma)片蓋好,進(jin)行催芽,每(mei)天用(yong)(yong)(yong)溫水(shui)沖濾一(yi)次(ci)。約5天時(shi)間,種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)萌動即可播(bo)種(zhong)(zhong)(zhong)(zhong)(zhong))。播(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)方(fang)法同(tong)冬(dong)播(bo),長(chang)期保持土壤濕(shi)潤,一(yi)般15天左右(you)出(chu)苗。畝用(yong)(yong)(yong)種(zhong)(zhong)(zhong)(zhong)(zhong)量2.5kg。
