Research and utilization of a novel cultivation technology for high-quality early-seasoned rice

GONG Shu ming, DAI Zhi ping, LIU Dong lin (The Agricultural Bureau of Shuangfeng County, Shuangfeng, Hunan, 417700, China)  
The two high quality early seasoned rice varieties Zhongyouzao 81 and Xiangliangyou 68 were used as the experimental varieties. The patterns of raising rice seedlings, number of tillers transplanted, nitrogenous fertilization rates, harvesting dates, and methods of pest control by pesticides were investigated in 1999~2000 in order to improve panicle bearing, seed set and high milled whole grain rate and reduce pesticide contamination, The major technical parameters for high yielding cultivation of high quality early seasoned rice were systematically analyzed together with practice of exploitation of high quality early seasoned rice in recent years, A novel cultivation pattern for high quality early seasoned rice of 6 000~7 500 kg per hectare was therefore formulated and extended to Shuanfeng County.
