It was composed of adjustable screw, stirrer, metering device housing and central metering sheave and so on. The sowing rate can be set by turning the screw to change the working length of the central metering sheave relative to the metering device housing. The stirrer inside of the sheave housing is used to prevent seeds overhead. And metering of different sizes of seed is adjusted by changing the position of internal components of the slot wheel mechanism. Innovative design on the structure of the central metering sheave was finished. According to the structure parameters and physical characteristic parameters, different seed sowing rate of per hectares was calculated. And then the working length scale of the central metering groove wheel was made. And there is a one-to-one correspondence between scale values and sowing quantity per hectare of different kinds of seed.展开更多

Clusters efficiently pool and distribute elements of production, and provide better division among small specialized firms in given local regions. Economic agglomerations are the typical spatial structures of clusters. Clusters drive forward industrialization, and this path of industrialization in China is similar to the industrialization wave based on industrial districts( IDs or clusters) with concentrations of SMEs that started in west European countries, particularly in Italy and Germany, since the 1960s. However, in contrast to developed EU countries, Chinese clusters are mainly concentrations of labor-intensive and low-tech industries, without independent intellectual property fights or leading brands. China's industrial clusters' capaciW for innovation is rather weak. Chinese clusters participate in the international trade and world division of production from the node of processing, stopping at the lower end of Global Value Chain of industrial production. By reviewing Zhejiang clusters, this study examines the innovation capacity of Chinese clusters in the process of development and industrialization, so as to provide advice on the future development of Chinese clusters.展开更多
