海南省儋州市橡胶树施肥管理问题与对策

合理施肥是保持我国天然橡胶高产稳产的重要措施。但目前我国胶园在施肥管理方面还存在很多不合理的地方。本文以海南省儋州市为例，通过调研国营农场胶园和民营胶园的施肥管理情况，发现目前胶园施肥管理存在的一些问题，如土壤样品缺乏代表性、样品化验分析时效性差、施肥配方精准化程度较低和缺乏合理的橡胶树施肥技术等，进而提出制定胶园土壤采样标准、加强快速分析测试技术研究、科学制定橡胶专用肥配方和加强施肥环节指导等具体完善措施，从而为提高儋州胶园施肥管理水平奠定一定基础。

Problems and Countermeasures of Rubber Tree Fertilizing Management in Danzhou County, Hainan Province

Rational fertilization play an important role in maintaining high and stable yield of natural rubber. However, there are many unreasonable aspects in rubber plantation fertilizer management at present. This study took Danzhou County as an example, and investigated status of rubber plantation fertilizer management for state-owned and private rubber plantations. Some problems in rubber plantation fertilizer management were found. These problems included lack of representative in soil samples, poor in time effectiveness of the traditional laboratory analysis method, imprecise fertilization formula, and shortage of rational fertilizing techniques. Accordingly, this research put forward some suggestions. They were developing criteria for soil sampling, accelerating study on rapid chemical analysis technique, establishing fertilization formula scientifically, and enhancing guidance in process for the fertilization.
