Abstract: [Objective] The study was aimed to adjust and optimize production structure of rice so as to meet the requirements of the development of aquaculture. [Method] Seventeen newly-bred domestic early long-grain rice varieties were introduced. With Zhuqing, the Anhui provincial high-yield rice variety, as control, the early long-grain non-glutinous rice varieties which had high yield, high protein and high brown rice rate and could meet the requirement of plant industry and breeding industry were selected. And supporting cultivation techniques were also studied. [Result] Zhuliangyou 819 and 99 were high-yield, high-protein and high-brown rice rate rice varieties. They could be used in demonstration and promotion of rice forage in Anhui Province. Nitrogen fertilizer could significantly increased protein content in brown rice, and the optimal proportion of nitrogen was 70%. [Conclusion] Early long-grain rice has broad applicative prospect.
