| 摘 要： | 以新兴引进种植的澳洲坚果为试材,研究了树盘覆盖处理对澳洲坚果园土壤水分、温度、养分、抽梢物候和生产性能的影响.结果表明:地膜和草覆盖都有明显保水作用,地膜覆盖兼有显著的增温效应,而覆草处理下土壤温度却明显低于对照,在高温季节有降温作用;覆草和覆膜不同程度地增加了土壤有机质和速效磷、钾等养分含量,速效氮在覆膜后有下降趋势,覆草后正好相反;覆草处理可促进澳洲坚果的抽梢量,显著提高澳洲坚果的最初及最终座果率、降低空花率,最终使产量获得提高;而覆膜处理后澳洲坚果座果率、产量均显著降低.

| Abstract: | Macadamia trees newly introduced for planting were selected as the materials. The macadamia trees were mulched around tree base to observe the change of soil moisture, temperature, nutrients, phenophase, and yields in macadamia orchard. Both plastic mulch and grass mulch had significant moisture-retention capacity. The plastic mulch also increased soil temperature significantly. The soil temperature was obviously lower in the grass mulch than the control, indicating that the grass mulch could lower soil tem... |
