Abstract
With the development of the technology of precision fertilizer in the world, the high working efficiency of the spinning disc spreader was manifested in the countries with developed precision agriculture, and saved lots of time for fertilization in die field. The performance test of spinning disc spreader was conducted under four different application rates with two different spread width in the field of National Experiment Station of Precision Agriculture; and the simulation curve of multi pass application was drawn when the spreader worked in the field through simulated overlap distribution patterns. And the values of actual fertilization amount, standard deviation, and coefficient of variation were calculated in the four different application rates with two different spread width, through these performance parameters the distribution uniform and application accuracy of the spinning disc spreader could be evaluated. The results indicated that the machinery worked the best with 15 m application width for small quantity of fertilization, and 20 m for large quantity of fertilization. The machinery can be popularized in whole China.关键词
