Increasing farm income by introducing agricultural techniques on pre- and post-rice cropping in the rainfed lowland area in Southeast Asia: A case study in Northeast Thailand

雨水灌溉的低地地区主要种植水稻单作，这被认为是农户经济的缺点和弱点之一。在这项研究中，我们发现，农场家庭劳动力和地下水的容量和质量是适合引进新的旱季作物在选定的调查地点在泰国东北部。在此基础上，进行了对照田农艺试验，以了解不同栽培方式下旱稻与旱稻轮作的产量效应。

Rain-fed lowland areas are mostly cultivated by rice mono-cropping and its regards one of the disadvantages and weakness of the farm household economy. In this research, we found that the farm family labor and ground water capacity and qualities are suitable to introduce the new dry season crops at a selected survey site in Northeast Thailand. Then agronomical experiments were carried out in the controlled fields in order to understand the yield effect of crop rotation between dry season crops and the wet season rice by the different cultivation method.
