In order to solve the problem of time-consuming and labor-intensive cotton topping, Wang Weixin, then dean of the College of Mechanical and Electrical Engineering of Shihezi University, began to develop cotton topping machines since 2001.
According to Tang Jun, the stationmaster of the Agricultural Technology Promotion Station of the Corps, the cotton topping machine developed by Shihezi University is the first in the entire corps. It is another major technological breakthrough after the cotton precision seeder and cotton picker. It has a very broad Prospects.
On July 11th, the cotton topping machine developed by Wang Weixin, director of the Academic Affairs Office of Shihezi University of Xinjiang Production and Construction Corps, was tested in the 143th Regiment of the Eighth Division of Agriculture and achieved success.
