Abstract: In order to clarify the growth features, lodging resistance, population formation and yield performance of mechanical precision hill-drop drilling rice, the experiment and demonstration of different types of rice varieties were carried out using the main rice variety in Shanghai as materials. The economic benefits and the changes of microbial population of soil after using the mechanical precision hill-drop drilling technique were analyzed in this study. The results showed that the mechanical precision hill-drop drilling rice has the characteristics of the shorter period of rice growth, the more tillers per plant, the suitable plants per block, the more weight of dry matter, the higher yield and the less cost. This technique showed high efficiency and less energy, thus it is possible to be populized in the rice production. This method is expected to meet the agricultural requirement in the city. Moreover, it leads to less carbon emission and has broad application prospect.
