| 摘要: |
| 为了解巨尾桉(Eucalyptus grandis×E.urophylla)内含物对其他植物的他感作用,分别用巨尾桉的新鲜枝叶和枯枝叶的水浸提液进行水稻、蕹菜(Ipomoea aquatica)和菜苔(Brassica parachinensis Bailey)花种子发芽试验。经鲜液供水的水稻种子平均发芽率、发芽势分别为95%、60%,略低于对照的97%和62%;蕹菜种子平均发芽率、发芽势为93%、62%,略低于对照的94%、72%;苔菜种子平均发芽率、发芽势为31%、22%,对照为99%、75%。枯液供水的水稻种子平均发芽率、发芽势为89%、52%,略低于对照的98%、65%;蕹菜种子平均发芽率、发芽势为87%、47%,低于对照的95%、59%;苔菜种子平均发芽率、发芽势为2%、2%,对照为98%、78%。说明巨尾桉枝叶水浸提液不同程度影响供试作物的种子萌芽。在巨尾桉林分下坡面不宜种植苔菜,进行水稻育秧或种植蕹菜时,应避免引用坡面水灌溉 |

| Abstract: |
| To make sure the effect of the inclusion of eucalyptus on the growth of other species, the seeds of rice, Ipomoea aquatica and Wancihua were used in the germinating trial. The seeds were respectively watered during the trial with the fresh water extract (from the fresh branches and leaves of Eucalyptus grandis×E. urophylla and the withered water extract (from the withered branches and leaves of E. grandis×E. urophylla), and the distilled water was used as control. Under the fresh water extract, the average germination rate (AGR) of paddy was 95%, slightly lower than the control (97%) and its average germinating energy(AGE) was 60%, similar to the control (62%);the AGR of Ipomoea aquatica (93%) was similar to the control(94%) and its AGE was 62%, lower than the control (72%);the AGR of Wancaihua was 31%,much lower than the control (99%) and its AGE was 22%, much lower than the control (75%).Under the withered water extract, the AGR of paddy was 89%, lower than the control (98%); its AGE was 52%, lower than the control (65%);the AGR of Ipomoea aquatica was 87%,lower than the control (95%); its AGE was 47%, lower than the control (59%);the AGR of Wancaihua was 2%, much lower than the control (98%) and its AGE was 2%, more lower than the control (78%).It revealed that water extract of branches and leaves of Eucalyptus grandis×E. urophylla could reduce the seed germination of the tested crops. In the lower slope of stand of E. grandis×E. urophylla, it should be avoid growing Wancaihua, and avoid irrigating with surface water on the slope when planting paddy and Ipomoea aquotica. |
