摘要

After long-term intercropping pastures in young coconut grove for 10 years, the soil pH of 0 -20 cm decreased 0.92 unit, the 20 - 40 cm decreased 0.75 unit, and in old coconut grove the soil pH of 0 - 20 cm decreased 0.82 unit, the 20 - 40 cm decreased 1.04 unit; after long-term intercropping pastures in young coconut grove for 10 years, the soil water content was lower than before, but higher than before , in old coconut grove the soil water content decreased above half than before and was lower compared with the young coconut grove; after long-term intercropping pastures in young coconut grove for 10 years, the soil organic matter of 0 -20 cm was higher than before, but the 20 -40 cm was lower, and in old coconut grove there were all lower; after long-term intercropping pastures in young coconut grove for 10 years, the soil total nitrogen content was a little lower than before, but in old coconut grove it decreased above half than before, but was higher compared with the young coconut grove. These results suggesed that long-term intercropping pastures in coconut grove, there must be applying fertilizer properly, and combining with proper lime or adopting legume-graminaceae rotation or legume-non graminaceae rotation.%幼龄椰园长期间作牧草,10年后0~20 cm层下降0.92个pH单位,20~40cm层下降0.75个单位,而成龄椰园0~20 cm层下降0.82个单位,20~40 cm层下降1.04个单位;幼龄椰园间作牧草,10年后土壤含水量有所下降,但仍比间作前高,而成龄椰园土壤含水量下降了一半以上,而且比幼龄椰园低;幼龄椰园间作牧草,10年后0~20 cm土层有机质含量比间作前有所上升,但20~40cm以下则低于间作前,成龄椰园均比间作前明显降低;幼龄椰园间作牧草,10年后土壤全氮含量略微降低,而成龄椰园下降了一半以上,但目前成龄椰园的土壤全氮含量比幼龄椰园的略高.建议椰园实行长期牧草间作,每年必须追施足够的肥料,并采取施入石灰或进行禾本科牧草与豆科或其它非禾本科作物轮作.
