Research progress on cultivation pattern, forming regulation and approach of high-yielding broadcasted rice.

The evolution process of broadcasted rice cultivation was reviewed and summarized in this paper.Several patterns of high yielding cultivation in broadcasted rice were highlighted.The process of seedling establishment and its eco-physiological characteristics of broadcasted rice were expounded.The biological advantages,high-yield forming regulation and approaches of broadcasting seedling rice were also clarified.The existing problems for large scale broadcasted seedling rice production were analyzed and the solving measures were put forward.Finally,the development of broadcasted rice in the future was forecasted.
