摘要

本研究旨在研究社区对种植水稻和经济作物的决策方法,包括在大地块农业系统下对农场的适当资源分配。研究区域位于泰国清莱省潘区,数据来自400名田间农人的抽样调查。采用的方法是与一位农学家代表和多标准决策(MCDM)专家一起建立一个多目标、多时期种植作物的数学模型。这是为了优先考虑替代作物的重要性,并找到适当的资源分配,以实现目标。结果表明,农学家最倾向于种植质量为0.179 Kg的日本水稻。,依次为移栽水稻、移栽糯米、大蒜、播种水稻、播种糯米。研究结果还表明,作物产品的价格波动导致更多地使用土地和劳动力来增加产量以弥补低价格,这也导致种植插秧水稻的机会成本更高。因此,在应季种植时种植移栽水稻被认为是最有效的方法,而在淡季种植时,可以种植大蒜或日本水稻。在大面积农业地区共同规划利用资源的集体模式,加上明确的销售目标,将带来资源的有效利用,并减少价格波动带来的收入风险和干旱造成的产量不确定。此外,解决劳动力短缺问题的技术发展也被认为是未来提高农民竞争力的重要途径。

Planning rice cultivation in a large plot agricultural system
This research aimed to study the approach of the community toward the decision to grow rice and economic crops, including appropriate resource allocation for use on a farm under a large plot agricultural system. The study areas were in Phan district, Chiang Rai province, Thailand, and the data were collected from a sampling of 400 field agriculturalists. The method used was to develop a mathematical model for growing crops with multi-objectives and in multi-periods, together with an agriculturist representative and experts in multiple-criteria decision-making (MCDM). This was to prioritize the importance of alternative crops and find the appropriate allocation of the resources to achieve the targeted goal. The results showed that agriculturists prioritized most toward the criteria for growing Japanese rice with a weight of 0.179 Kg., followed by transplanted rice, transplanted glutinous rice, garlic, sown paddy rice, and sown glutinous paddy rice, respectively. The study’s results also showed that the price fluctuation of the crop products resulted in more use of land and labor in order to increase the production to compensate for the low price, and this also resulted in the higher opportunity cost of growing transplanted rice. Therefore, growing transplanted rice during in season planting was considered the most effective way, while during the off season, either garlic or Japanese rice could be grown. A collective pattern for planning for using resources together in large plot agricultural areas, together with a clear marketing target would bring about effective use of the resources and reduce the risk in revenue from the fluctuation in prices and uncertainty of yields from drought. Moreover, technology development to solve the problem of the lack of labor would be deemed an important approach toward the enhancement of the competitiveness of agriculturists in the future as well.
