Title: Study on Nutrition Characteristics and Fertilizer Effect for Rice Yangliangyou 6
Abstract: Through field plot experiment,nutrition characteristics and the fertilizer effect for hybrid rice(Oryza sativa L.) Yangliangyou 6 in Jingshan were studied. The results showed that nitrogen fertilizer had the greatest impact on the yield, followed by potassium fertilizer,and the effects of phosphate fertilizer on the yield was not obvious. In General, fertilizer applied quantity in the actual production should be N 200 kg/hm2,P2O595 kg/hm2,K2 O 165 kg/hm2. Leaf SPAD values were significantly influenced by nitrogen application amount during jointing booting stage, and had no obvious relationship with phosphate and potassium fertilizer. Leaf SPAD value of 42.16 can be used as the indicator in rational application of nitrogen.
