Field latex is an important raw material in Thailand, produced by a large number of smallholders and handled by numerous local traders. This diversity of stakeholders involved along the production and marketing chain could result in the variability of the latex quality delivered to the factories. Latex processing industries need a raw material with consistently specified properties. Therefore, it is crucial to identify the factors that could affect latex properties. However, a complete description of the practices from the farmer to the factory is missing. Thus, a study was conducted to (1) characterise the upstream practices, (2) identify variable practices and (3) analyse farmers’ and traders’ perceptions of field latex quality that are believed to influence their practices. A survey was conducted with 398 field latex producers and 182 field latex traders distributed in eight provinces of Southern Thailand. The results showed that some agronomic practices in the mature plantations presented homogeneity (planting material, weed control, management of the inter-row of the plantations) while others (fertilisation, tapping panel treatment, harvesting practices) presented important diversity. Farmers’ and traders’ post-harvest practices presented limited sources of contamination. Nonetheless, for both stakeholders, an important possible source of variability was the quantity of latex preservative used. Finally, the analysis of the practices and the perception of the stakeholders clearly showed that field latex quality was determined both before and after harvesting. Research is still needed to analyse the impact of some agronomic practices on field latex quality. Latex traders also appeared as key stakeholders dealing with the quality.

泰国南部的田间乳胶生产:一项关于农民和商人的做法的研究,这些做法可能会影响交付给工厂的天然橡胶乳胶的质量

田间乳胶是泰国的重要原材料,由大量小农生产并由众多当地贸易商处理。涉及生产和销售链的利益相关者的这种多样性可能会导致交付给工厂的乳胶质量发生变化。乳胶加工业需要具有一致指定特性的原材料。因此,确定可能影响乳胶性能的因素至关重要。但是,缺少从农民到工厂的做法的完整描述。因此,进行了一项研究,以(1)表征上游实践,(2)确定变化的实践,以及(3)分析农民和贸易商对田间乳胶质量的看法,认为这会影响他们的实践。对分布在泰国南部八个省的398家乳胶生产商和182家乳胶贸易商进行了调查。结果表明,在成熟的人工林中,某些农艺措施表现出同质性(种植材料,杂草控制,人工林行间管理),而其他的(施肥,轻敲面板处理,收获方式)则表现出重要的多样性。农民和商人的收获后实践表明污染源有限。但是,对于两个利益相关者而言,可能的重要可变性来源是所使用的乳胶防腐剂的数量。最后,对实践和利益相关者看法的分析清楚地表明,田间乳胶质量是在收获前后确定的。仍需要进行研究以分析一些农艺实践对田间乳胶质量的影响。乳胶贸易商也成为处理质量问题的主要利益相关者。
