Title: Effect of the Integrated Application of the Organic Fertilizer, Inorganic Fertilizer and Soil Regulator on Rice Yield
Abstract: [Objective] The impact of the integrated application of organic fertilizer and chemical fertilizer,the application of soil regulator on rice yield was experimented.[Method] The different treatments including application of different types of organic fertilizer or inorganic fertilizer,and the application of soil regulator or not were designed in the experiment.[Results] The organic fertilizer can promote rice tillering and its fertilizer efficiency was slowly released,which treating efficiency in the early growing period of rice was not better than that of chemical fertilizer,however,in the late growing period of rice,significantly better than that of chemical fertilizer.The rice average yield was gradually increased with the increment the proportion of organic fertilizer application,and the treatment of compound fertilizer of 75.0 kg/hm2 + AP of 22.5 kg/hm2 + dried rice straw of 4 000.0 kg/hm2 could promote the formation of the highest rice average yield of 8 724.30 kg/hm2,which was 6.7% higher than that of CK.The application of soil regulator was beneficial to rice yield-increasing and the average rice yield was up to 8 440.05 kg/hm2.[Conclusion] The organic fertilizer and soil regulator can promote rice growth and development for many more tillers and obvious yield-increasing.The integrated application of compound fertilizer of 75.0 kg/hm2 + AP of 22.5 kg/hm2 + dried rice straw of 4 000.0 kg/hm2 and soil regulator made the rice yield being the maximum one and the average yield was up to 8 791.95 kg/hm2.
