In order to using the fertilizer scientific,economical and environmental,realizing the target of increasing the yield,improving the benefit and protecting the environment,taking Suijing No.10 as experimental material to study the effect of five different fertilizing models on rice yield and economic benefit.The results showed that:the yield,net output and rate of input and output of the model of additionally fertilizing for three times was the highest,it was the best one.The difference between once additional fertilizer and twice additional fertilizer was not significant,generally speaking,the model of once additional fertilizer was better.Both the yield and the net output of the model of applying once fertilizer was the lowest,it was not suitable for the rice production in Tieli city.
