Design and Experiment of Fertilization Mechanism for 2BZD-2 Intelligent Electric Planter

In order to reduce the environmental pollution in the application of chemical fertilizers, improve the growth environment of crops and improve the utilization rate of fertilizers, this paper, in combination with the agricultural industry standard of the People's Republic of China and the agricultural technology requirements of fertilization, developed a kind of intelligent Precision seeding machine, that is, 2BZD-2-type intelligent no-tillage electric planter fertilization institutions, and to determine the main components of the best parameters. In the control system, the core of its technology for the microprocessor technology and sensor technology, can achieve real-time fertilizer, automatic, single variable control. The experimental results show that the performance of the equipment is good, and the indexes meet the technical standard of precision sowing machinery and the technical conditions of precision planter. The technical conditions of the cultivator of 2BZD-2 type intelligent no-tillage electric planter are designed. The coefficient of variation is far less than the national standard, and meet the agronomic requirements.
