摘要 在福建漳州和永安开展绿竹种源引种试验,研究各地种源水文效应,结果表明:在永安点,造林3 a后,①、⑤、②、⑨号种源林冠层和地下部分生物量均较大,持水量较高,从水土保持的作用来看,不同种源的Φ值均存在增长最快点,⑨、⑥、③号分别居前3位;漳州的③号种源林冠层和地下部分生物量均较大,持水量较高,③、⑤、⑨号种源降水截留能力较强.综合以上分析结果,可得出永安点⑨号种源(赛岐)、①号种源(福安)、②号(永春)及⑤号(永安)种源综合指标最高,在水文效应方面最好,建议这4个种源可作为当地绿竹推广试验的参考种源.漳州点⑨号种源(赛岐)种源综合指标值最高,可作为当地重点推广参考种源. The introduction experiment about hydrological effect of Bambusa oldhami provenance in Zhangzhou and Yong'an. The results showed that: in yong'an, 3 years after afforstation, the biomass and water holding quantity of forest canopy and underground of (1). (5)、 (2)、 (9) provenance were relatively much. On the function of soil and water conservation, the Φ value of various provenances all have the point of most fast increase, and the number (9)、 (6)、 (3) were ahead of other provenances ; in Zhangzhou, the biomass and water holding quantity of forest canopy and underground of number (3) provenance were relatively much, the function of rainfall interception of the number (3)、 (5)、 (9) was relatively good. From the above, we can conclude : in yongan, the comprehensive indexes of the number (9)、 (1)、 (2)、 (5) exceeded other provenances, and they were best in hydrological effect, so we suggest they can be regarded to consult provenance of B. oldhami popularization experiment in local area. In Zhangzhou, the comprehensive indexes of the number (9) was highest and can be used to important popularization provenance in local area.
