Research on Hill-drop Drilling and Row Drilling of Rice
The yield and yield components of rice under hill-drop drilling and row drilling were studied, using Huanghuazhan and Tianyou 998 as material. The results showed that the emergence rate is similar under mechanical hill-drop drilling and row drilling. In this experiment, the yield with mechanical hill-drop drilling is higher than row drilling, increased by 4.75% and 13.96% for Huanghuazhan and Tianyou 998 respectively.
