水稻是我国主要的粮食作物之一,是我国粮食作物中单产最高的作物,高于世界稻谷平均单产近1倍,位居世界前列。由此可见,水稻在我国粮食生产中占有举足轻重的地位,对世界水稻生产也有重大的影响,探讨21世纪我国水稻种植机械化发展方向,具有非常重要的意义。 Rice is one of the main grain crops in China. It is the highest-yielding crop among the grain crops in China, which is about one time higher than the average rice yield in the world and the highest in the world. Thus it can be seen that rice plays a decisive role in grain production in our country and has a significant impact on world rice production. It is of great significance to explore the development direction of rice planting mechanization in the 21st century.
