Zhengyang, Henan province is the largest county for peanut planting in China, with a planting area of more than 1.6 million mu and an annual output of more than 500,000 tons of peanuts. At present, the growth of peanut in Zhengyang county is better in general, and it has entered the harvest stage. In order to ensure a high yield of peanut in the whole county, the Agricultural Machinery Center of Zhengyang county fully played its role in preparing for the “Three autumn” agricultural mechanization production to ensure the smooth operation of the“Three autumn”production.

A comparative experiment of the picking process of the picking peanut machine, was carried out in Qingyuan by the agricultural machinery technology center of the county, combined with the peanut harvesting machinery manufacturers, several peanut harvesters from peanut machinery manufacturers participated in the field comparison. Everywhere the harvester went, rows of peanuts were uprooted, the plants were picked clean and then scattered on the ground. The threshing process was carried out directly in the harvester, after the peanuts in the harvester were filled and dumped into the truck, the harvester can then return to the field. The Agricultural Machinery Technology Center of the county has held the peanut picking machine contrast test for 3 years in succession, and achieved good results, the peanut picking machine performance obtain a further enhancement. This time, from pick up rate, pick fruit rate, broken rate, and the rate of impurities to test, the performance of the 4 peanut harvesters that participated in the test has been greatly improved compared with previous years.

The improvement of the performance of the peanut harvester is closely related to the increase of farmers’ income. The less loss, the more income for the farmers. In addition, the mechanized harvesting of the peanut has greatly solved the problems of high labor cost and difficulty in recruiting workers of the cooperative. “Instead of three to four farmers picking one mu of peanuts a day by hand, this machine can pick 20 mu of peanuts a day, greatly improving the picking efficiency of the peanut and reducing the breakage rate of the peanut.
