摘要:
香樟对邻体植物具有化感作用,为获得良好的园林绿化配置效果、促进科学的林地管理,采用盆栽试验探讨香樟凋落叶分解对牵牛花生长和生殖的影响,以及施氮对凋落叶分解效应的影响. 试验设置对照(CK)和25 g/盆(L25)、50 g/盆(L50)、100 g/盆(L100)3个水平凋落叶处理,凋落叶分解34 d后开始施氮处理(0.39 g尿素/盆,分3次施入). 结果表明:(1)凋落叶分解明显抑制了牵牛花株高、基径、叶面积和生物量的积累,其中,株高降低32.85%-83.78%,茎粗减小5.23%-23.00%,叶面积减小30.31%-58.47%,生物量降低40.34%-84.54%,且剂量越大作用越强越持久,而施氮能明显减轻牵牛花生长受抑制的现象. (2)各水平凋落叶处理后,牵牛花始花期延迟2.5-10.0 d,开花持续时间延长6.3-11.4 d,开花数量增加0.5-3.3朵,但花朵品质较之对照降低,且牵牛花种子百粒重随着凋落叶添加量的增加而减小;施氮后,上述指标在各剂量凋落叶处理间的差异很小或无差异. 综合各项指标可见,香樟凋落叶分解会对牵牛花生长发育产生明显的抑制效应,这可能与香樟凋落叶分解释放有毒物质作用于牵牛花有关.
Abstract:
In plant configuration of landscaping, herbaceous plant is often inter-planted with ornamental tree species. But unreasonable plant collocation may reduce the effectiveness of afforestation for the inhibition effect of tree on the growth of understory, and further more affect the greening effect. Camphor (Cinnamomum camphora) is widely planted in landscaping accompanying herbaceous plants including morning glory (Pharbitis nil). But camphor was reported to have allelopathic effect on its adjacent plant, therefore correct selection and collocation of plants has important significance to obtain good greening effect. This research aimed to study by a pot experiment the effects of decomposing leaf litter of Cinnamomum camphora on the growth, phenological traits of Pharbitis nil, as well as modification of these effects by nitrogen application. Three application rates of C. camphora leaf litter including 25, 50 and 100 g/pot (denoted by L25, L50 and L100, respectively) and a control (CK) were implemented. Nitrogen application began on the 34th d of decomposition, with 0.39 g urea being divided into three equal portions and added continuously to each pot. The results showed that (1) The height, basal diameter, leaf area and biomass production of Pharbitis nil were all inhibited sharply by exposure to the leaf litter, being decreased by 32.85%–83.78%, 5.23%–23.00%, 30.31%–58.47%, and 40.34%–84.54%, respectively, with the inhibition effect increasing both in intensity and stability with the increase of leaf litter. Such inhibition effect was obviously alleviated by exogenous nitrogen application. (2) The flowering dynamics of Pharbitis nil was greatly impacted by the leaf litter, with the flower initiation 2.5–10.0 d later and the flowering duration 6.3–11.4 d longer compared to the control. Although the leaf litter-treated plants exhibited more (0.5–3.3) flowers than the control, their quality decreased, and the hundred-grain weight of the seed decreased with the increase of leaf litter. However, the differences?among treatments in the reproductive parameters mentioned above reduced after nitrogen fertilization. The results indicated that leaf litter of C. Camphora has a great allelopathic effect on morphological and reproductive growth of Pharbitis nil, which may be attributed to the release of phototoxic substances during the decomposition process.
