The mechanism of high-yielding in rice under dry-raising and thin-planting and its regulating technique Ⅰ.Advances in the mechanism of high-yielding in rice under dry-raising and thin-planting and its prospects

Wang Songliang; Lin Wenxiong(College of Crop Science, Fujian Agricultural University, Fuzhou 350002)  
The general developping situation of rice cultivation by dry-raising seedling and thin-planting in China and its theorical base are briefly introduced. The advances in the mechanism of high-yielding in rice under dryraising and thin-planting were mainly reviewed. Besides that, the problems were analysed and the directions for further studies were also suggested, which were: (1) the relation between microecological environment in dryraising bed with fertilizing and seedling quality; (2) the relation between root advantages of dry-raising seedling and formation of organs and yield; (3) and the relation between high-yielded populational quality under dry-raising and thin-planting and its formation of yield.
