水稻生产力的创新是水稻研究的主要目标。然而，许多研究倾向于单独分析影响生产力的各种因素，而农民将其稀缺的资源投入到对真实的农场的多种因素产生影响的农业投入中。本研究评估了柬埔寨农民田间学校（FFS）培训期间实施的害虫综合管理对水稻种植的生产效率、产量和盈利能力的有效性。在3年内，从3个省随机选择了270个在早期湿季、湿季和旱季种植的水稻FFS，使用6个成本相关因素（种子、种植方法、田间管理、肥料使用、农药施用和收获）分析生产实践和生产力。结果发现，产量和利润显着较高的技术建议的做法（TR）比传统的农民的做法（FP）。然而，由于在FP中过度使用种子和农药，生产成本相反，这两者都与FP和TR的产量增加无关。因此，FFS方法是一种知识密集型田间管理工具，能够合理使用农业投入，预计对可持续的水稻生产改良非常有效。
ABSTRACT Innovation in rice (Oryza sativa) productivity improvement is a major goal for rice research. However, many studies have tended to analyse the various factors that affect productivity separately, while farmers invest their scare resources in farm inputs that impact on multiple factors in the real farm. This study assessed the effectiveness of integrated pest management practised during farmer field school (FFS) training in Cambodia on the production efficiencies, yields and profitability of rice farming. In total, 270 FFSs on rice cultivated in the early wet, wet and dry seasons were randomly selected from three provinces in 3 years to analyse the production practices and productivity using six cost-related factors: seed, planting methods, field management, fertilizer use, pesticide application and harvesting. It was found that yields and profits were significantly higher with the technically recommended practices (TRs) than with traditional farmer practices (FPs). However, the reverse was true for production costs due to the overuse of seed and pesticides in FP, neither of which are correlated with yield increase for both FP and TR. Thus, the FFS approach is a knowledge-intensive field management tool that enables the rational use of farm inputs and that is expected to be highly effective for sustainable rice production improvement.
