| 摘 要： | 研究成龄胶园条件下间作不同姜科作物对胶园土壤养分和土壤酶的影响,为成龄胶园姜科作物间作合理施肥和土壤培肥提供理论依据。以间作3种姜科作物的胶园为处理,以单作胶园土壤为对照,采用土壤常规分析方法分别测定土壤养分和土壤酶。结果表明：间作的3种姜科作物对胶园土壤的全钾、硝态氮含量（除生姜外）、pH（除生姜外）、酸性磷酸酶活性、过氧化氢酶活性（除草豆蔻外）的影响不显著;显著降低了有机质、全磷、速效磷、全氮（除草豆蔻外）含量、土壤脲酶活性;显著增加了铵态氮（除砂仁外）、速效钾及土壤蔗糖酶活性。这些结果说明,间作姜科作物能改善土壤的土壤硝态氮、铵态氮及速效钾含量,短时期内能提高土壤的供氮、供钾能力,但降低了土壤磷含量和土壤磷的供应能力。由此可见,在成龄胶园内进行间作,必须加强间作物施肥,以实现土壤养分收支平衡,维护土壤功能、保护土壤质量。

| Abstract: | The objective of this study is to investigate the effect of intercropping zingiberaceae crops with mature rubber on soil nutrients and soil enzymes. Soil nutrients and soil enzymes of mature rubber plantation with different intercropping Zingiberaceae crops were determined by conventional determination method.Results showed that effects of intercropping different Zingiberaceae crops in mature rubber plantation on total potassium, NO3-N（except intercropping ginger）, pH value（except intercropping ginger）, soil acid phosphatase activities, soil catalase oxidase activities（except intercropping Alpinia katsumadai） were little（P〉0.05）. The organic matter content, total phosphorus, available phosphorus and total nitrogen（except intercropping Alpinia katsumadai） content and soil urease activities in mature rubber plantation soils significantly decreased after intercropping 3 species of Zingiberaceae crops. However, the NH4＋-N content（except intercropping Amomum villosum）, available potassium content and soil sucrase activities increased significantly. These results demonstrated that intercropping Zingiberaceae crops could improve the soil nitrogen and potassium supply capacity and decrease soil phosphorus supply capacity in short time. At the same time, these findings showed that in order to achieve the long-term success of intercropping in mature plantation, people must strengthen the crop fertilization to make soil nutrient balance, maintain soil function and protect soil quality. |
