| 摘 要： | 海南玄武岩砖红壤香蕉园的连作生物障碍严重,轮作是缓解香蕉园连作生物障碍最有效的方式之一。本研究使用主成分分析法结合实测数据,根据不同土壤指标的敏感程度以及指标间的相关度筛选出的土壤pH、速效钾、有效磷、碱解氮、有机质、细菌总数、真菌总数、放线菌总数、线虫数、香蕉枯萎病病原菌数量10项指标对5种轮作模式下的香蕉园土壤质量进行综合评价。结果表明:土壤质量综合评价指数可以较好地反映土壤实际的质量,并能够在一定程度上反映香蕉的产量及发病状况,是较为理想的土壤评价指标;用所得到的综合评价指数对5种轮作模式及香蕉连作进行对比可以发现轮作能有效地提高土壤质量,降低香蕉发病率,提高香蕉产量,其中菠萝、甘蔗、辣椒、冬瓜4种作物相对适合香蕉的轮作。

| Abstract: | Continuous cropping obstacle is very serious in the banana plantation with basalt laterite in Hainan, reasonable rotation is one of the most effective methods to alleviate this problem. In this study, 10 indexes including pH, organic matter, available N, P and K, populations of bacteria, fungi, actinomycetes, nematode and pathogenic bacteria of banana wilt were selected to assess basalt laterite quality in banana orchards under 5 rotation modes by PCA method. The results showed that integrated quality index could actually indicate soil quality and the output and disease status of banana orchards, thus is an ideal indicator for soil quality assessment. Crop rotation could effectively improve soil quality, reduce wilt incidence and increase banana yield. Pineapple, sugar cane, chili and white gourd are suitably rotated with banana. |
