Abstract: As a kind of conservation tillage, seedling-broadcast with no-tillage techniques is a labor saving, time saving, cost saving and high efficiency technology of farmland. This technique has been widely studied and applied to paddy in China in recent years, bringing farmers convenience and high incomes and it is the innovation of rice cultivation technique. This paper briefly reviews the formation and development of seedlingbroadcast with no-tillage techniques, and mainly narrates the development of this technology research at home and abroad and forecasts the future of this technology. Through summarizing the development of seedlingbroadcast with no- tillage techniques and analyzing the growth of rice and the ecological benefit of this technique, we know seedling-broadcast with no-tillage techniques can indeed alleviate the shortage of China’s rural labor. In addition, it is also in line with our environment-friendly development. However, there isn’t a perfect solution in solving the problems of diseases, insect pests, weeds of rice and seeding standing slowly, which requires us to research more in the future, so that this technology can be further refined and innovated and have a long-term development.
