| 摘 要： | 通过不同种养模式下椰园田间试验，研究了椰园间种牧草-养鸡、间种牧草-养羊及椰园自然状态下的杂草-养鸡3种不同种养模式对土壤养分的影响。结果表明： （1）不同种养模式下土壤pH值与对照相比，椰园间种牧草-养鸡模式显著提高土壤pH值，其它种养模式对土壤pH值影响不显著； （2）不同种养模式下的土壤有机质含量高于对照，且椰园间种牧草-养鸡模式土壤有机质显著高于其它处理，杂草-养鸡、间种牧草-养羊与对照区土壤有机质含量差异未达显著水平； （3）在不同种养模式下0~20 cm表层土壤中有效氮、有效磷及有效钾的含量均显著高于对照；在20~40 cm土层中各处理养分含量差异不显著。

| Abstract: | Through the test of different modes of planting and feeding in coconut-garden fields,the influence of three different modes of planting and feeding,intercroping grass and feeding Wenchang chickens,intercroping grass and feeding goats,feeding chickens and intercroping weeds in natural coconut-garden fields,on soil nutrients were studied.The results showed that:(1)In these three modes of planting and feeding,by comparing the control soil with the sample soil,different modes of planting and feeding had certain influence on the soil pH,the mode of intercroping grass and feeding chicken had significant influence on soil pH,the other two modes had little influence on soil pH.(2)The soil organic matter was higher in the mode of planting and feeding than that of control soil,and the soil organic matter in the mode of intercroping grass and feeding chickens was significantly higher than that of other modes,the soil organic matter in the mode of intercroping weeds and feeding chickens and in the mode of intercroping grass and feeding goats had slight difference with that of the control soil.(3)In different modes of planting and feeding,the content of available N,available P,available K of the top soil from 0 to 20 cm in the different modes of planting and feeding increased significantly compared with that of the contol soil,the nutrients in top soil from 20~40 cm did not change in all the situations. |
