| 中文摘要 | 试验采用L16(45)正交试验设计对马山县古寨乡喀斯特丘陵坡地麻竹林进行尿素、钙镁磷肥、沸石3种肥料的施肥试验,研究不同施肥组合对单株或单位面积的地上生物量分配影响。结果表明:施肥对提高新竹地上生物量具有一定的促进作用,以施用尿素500 g+钙镁磷肥1 000 g+沸石5 000 g、钙镁磷肥4 000 g+沸石5 000 g效果显著,且极显著高于不施用的处理,但在低P、低Si、无N或无P或无Si等3种情况下,杆重比例均为较低。各处理以竹秆所占的比例最大,为61.0%～88.8%,其次是枝。各器官比例与肥料施用比例没有直接的关系。初步认为,单株或单位面积地上部分总生物量、杆重达到较高时,秆、枝、叶较适合比例为73%～74%、18%～19%、8%。杆重比例的高低与单株或单位面积杆重、地上部分总生物量的关系无规律性,而单株杆重是影响单位面积杆重、地上部分总生物量的主要因子,随着各处理单株杆重增加,单株或单位面积地上部分总生物量也增加。枝、叶所占比例无规律变化,但各处理中杆、枝比例表现出高杆低枝或低杆高枝的趋势。杆、枝和地上部分总生物量的增减与叶量比例的关系无规律性变化,叶片数量对单株或单位面积的竹杆、竹枝和地上部分总生物量影响不显著,这可能与麻竹生物学特性有关。认为留好母竹,合理施用肥料是提高喀斯特丘陵坡地麻竹产量的最佳途径。 |
