The competition is carried out on a plastic field with the length of 27.50 meters, the width of 4-4.50 meters and the height of the surrounding coamings of 23-25 centimeters. The judge judges the distance between the big ball and the small ball thrown by both sides and the score. However, the existing plastic ground throwing court has no unified and standard technical requirements, such as sandy soil, asphalt, plastic particle ground and the like, the elasticity and the friction coefficient of the ground are insufficient, but the ground is required to have low elasticity and large friction coefficient in the ground throwing game. Three techniques are used in plastic ball throwing games, one is a rolling ball technique, the ball is thrown out by hands and is made to be as close to a target ball as possible after rolling on the ground, and if the ground is not smooth enough, the rolling track of the ball is seriously influenced; the friction coefficient is too small, the rolling time of the ball is too long, the difficulty is increased for the player to play, the competition time is prolonged, and the project popularization is not facilitated; the other two technologies are a throwing ball technology and a rolling ball technology, and both the throwing ball technology and the rolling ball technology need to hit a ball to be hit by means of ground, but the technical application of the athlete can be influenced by the slightly larger elasticity of the ground, the exertion of the athlete is seriously influenced, and the project development is not facilitated.
