Zoysiagrasses are warm season grasses native to China, Japan and other parts of Southeast Asia. The species was named to commemorate an 18th century Austrian botanist, Karl von Zois. In 1911, Zoysia matrella was introduced into the United States from Manila by a U.S.D.A. botanist, C. V. Piper. Because of its origin the grass was commonly called Manila grass.
The third species of Zoysia used for turf is called Korean velvet grass or Mascarene grass, Zoysia tenuifolia. It is a very fine textured species, but is the least cold tolerant of the three species. Zoysia tenuifolia is native to the Far East and was introduced in the U.S. from the Mascarene Islands. In the U.S. it is used in southern California as a low growing ground cover.

Piper described the grass as abundant on or near the seashore in the Philippine Islands. When closely clipped, it made a beautiful lawn according to Piper's notes. He suggested that the grass had unusual promise as a lawn grass along the Gulf Coast and Atlantic coast of Florida.
Zoysia japonica, sometimes called "Japanese lawn grass" or "Korean lawn grass", is a coarser textured, but more cold hardy species than Zoysia matrella. Zoysia japonica was introduced into the United States in 1895 from the Manchurian Province of China. In the United States, Zoysia japonica could be expected to do very well as far north as Maryland. It is a seeded variety of Zoysia.
1. Adaptability and economy (1) The new backpack-type airflow rice throwing machine is small in size, light in weight, simple in operation, convenient in use, and does not require a dedicated machine for cultivating roads. In the plains, hills, shallow mountain areas have a strong adaptability. It can also be used in one machine, which can throw parasites and spray pesticides. (2) The economic and practical investment is small. Generally, the price of a throwing machine is purchased in the range of 850 to 1100 yuan, which is suitable for purchase by family farms, villages, groups, and joint households. (3) Broadcasting a single acre with a new type of transplanter rice throwing machine generally takes only 12 to 15 minutes, and the working efficiency is 4 to 6 times that of manual throwing, and 20 times that of artificial transplanting. (4) The machine has good throwing uniformity, flexible maneuverability, long throw distance, and easy adjustment. (5) About 25% of the water resources are saved, and the management of Daejeon water promotes the distribution of water by inch of water, and it is dry and wet to harvest. (6) The cost-saving effect is obvious. It can increase rice production by 10%-15% per acre, save cost, and produce high overall economic benefits. 2. New Knapsack Rice Throwing Machine The new knapsack rice throwing machine is composed of four parts: the engine, the ventilation pipe, the connection support frame, and the storage tray (with arc-shaped casting trough). The engine is powered by a two-stroke small backpack-type gasoline motorized spray duster. (1) The engine is equipped with model number and power. 1 Model: It is more suitable to use Shaanxi Weinan-fenglin brand 3MF-2, 3MF-4 and Beijing Dongfanghong brand-18AC two-stroke gasoline motorized spray duster as power machine. 2 Power: General requirements in the 1.84 ~ 2.94 kilowatts (2.5 - 4 horsepower). Speed ​​7000-7500 rpm. (2) The main technical parameters of the casting machine 1 Productivity: 4 ~ 5 acres / hour. 2 flat shooting distance: 13 to 17 meters. 3 vertical ejection: 8-10 meters. 4 into the mud depth: 5-20 mm. 5 Staffing: 3 people, including 1 operator, 2 persons for transfer. 6 The mixture ratio of gasoline and oil is 20:1.
