贵州龙里县推广山地丘陵农机—— 机收划算，这笔账“老把式”算得清楚（秋收进行时）

Core Viewpoint - The article highlights the increasing adoption of mechanized rice harvesting in Guizhou Province, showcasing the efficiency and economic benefits of using machinery over traditional manual labor in rice farming [2][5]. Group 1: Mechanization Benefits - The use of harvesting machines significantly reduces the time required for rice harvesting and processing, with one farmer reporting that it takes only 30 minutes to complete the process for one acre, compared to two days with manual labor [3][4]. - The cost-effectiveness of mechanization is evident, as hiring a machine costs around 100 yuan per acre, while manual labor previously cost 200 yuan per person per day [3][4]. - The mechanization process also minimizes losses, with improved techniques leading to a reduction in the amount of rice lost during harvesting [4]. Group 2: Training and Skill Development - Local training programs for operating harvesting machines have been implemented, enhancing the skills of farmers and improving harvesting efficiency [4][5]. - Farmers are learning to navigate challenging terrains effectively, which is crucial for maximizing yield and minimizing losses [4]. Group 3: Agricultural Policy and Support - The local government is promoting high-standard farmland construction and providing subsidies for agricultural machinery purchases, which is increasing the mechanization rate in the region [5]. - The mechanization rate in the village has surpassed 70% and is expected to reach 85% this year, indicating a strong trend towards mechanized agriculture [5].
