Abstract
Potato, which is one of the most important grain crops in our country, is growthing in a rather huge area. In 2007, potato’s planting area and output of China situated in the first place of the whole world. Although the ultimate output is huge, the per unit area yield quantity is at a rather low palce. The tow primary reasons for this situation are that we are behindhand in the way of planting and in the mechanized level. Therefore, the currently primary mission is enhances the per unit area yield quantity. Generally speaking,we could arrive at this aim through two ways: First, improving the way to plant; Second, enhancing the mechanized level of planting. At now, raising the mechanized production level is the most effective way. This will request each kind of potato-planting machine with advanced performance, high efficiency of planting, strong universal property and adaptability, and simple structure that is easy to be produced and maintained to be designed unceasingly and widely promoted and applicated vigorously.
Rises to transport the chain potato seeder is one kind of sowing seeds massive potato seed tuber's seeder. With its simple structure, reliable operation, high efficiency, and hurtless to plants, this machine is widely applicated both in domestic and foreign country.
