儋州市热科院试验场橡胶园土壤养分状况分析

Soil Nutrition Analysis in the Farm of CATAS in Danzhou Region

为了解海南省儋州市中国热带农业科学院试验场橡胶园土壤养分状况,分析试验场4个生产队不同林龄的胶园和临近防护林的土壤养分状况。结果表明,试验场橡胶园土壤呈酸性,有机质、全氮、全磷、全钾、速效氮、速效磷和速效钾在不同林段土壤均呈不同程度差异。胶园土壤多个营养因子优于或相似于防护林,表明胶园养分处于相对平衡状态。

To understand the soil nutrition status in Chinese academy of tropical Agricultural science proving ground in Hainan,Danzhou,soil samples from 4 different production teams which consist of 4 different age stands and 3 protection forest stands were analyzed.The results showed that the acid soil from all stands varied differently in many aspect of soil nutrition,including organic matter,total nitrogen,total phosphorus,total potassium,available nitrogen,available phosphorus and potassium.The soil nutrition of rubber plantation was similar with protection forest,or even better than protection forest in some nutrition elements.These results indicated the relatively balance of soil nutrition in rubber plantation.
