Abstract: At present, the fertilization process of rice production in China is largely followed by manual scattering fertilization, which has problems such as waste of fertilizer, high labor intensity of farmers and pollution of people’s living water sources. Therefore, according to the agronomic requirements, the overall structure and component design of the rice spiral pushing type lateral deep fertilization device, the performance test of the main working components and the performance test of the whole machine were carried out.The structure design, parameter design and field test of the whole structure and key working parts are introduced in detail.Through a large number of practical field transplanting and lateral fertilization operations to assess the device performance, and through analysis of test data, it is known that with synchronous spiral force behind the type of rice planting and deep side fertilizing technology and device is to change the traditional rice fertilization model and the granular fertilizer can precise and quantitative in rice seedlings roots sounding position, to save about 20% compared with the traditional fertilizer, greatly improve the fertilizer utilization ratio and reducing fertilizer pollution of nearby rivers.
