Abstract:

Six treatments with three transplanting densities and two nitrogen application rates were set up to investigate the possibility of stablizing yield under the condition of nitrogen fertilizer reduction in different regions of Liaoning province. The results showed that there was no significant difference in rice yield between the reducing 10% nitrogen fertilizer treatment and the normal nitrogen fertilizer treatment in different regions, and proper increase of transplication density was one of the effective ways to reduce nitrogen and stabilize yield. The more suitable density for Yanfeng 47 in Haicheng and Liaojing 401 in Liaozhong was 2.4×10 5 hole/ha. The number of effective panicles of Yanfeng 47 in Haicheng and Liaojing 401 in Liaozhong reached about 4.0×10 6/ha and 3.7×10 6/ha, respectively. While the yield of Liaojing 401 was high at the two densities of 3.3×10 5 hole/ha and 2.4×10 5 hole/ha under the normal nitrogen fertilizer treatment and the density of 3.3×10 5 hole/ha under the reducing 10% nitrogen fertilizer treatment in Zhuanghe. The relative yield was more than 110% in these treatments.

Key words: Rice, Nitrogen reduction, Stable yield, Pattern of fertilizer and density
