Using the indica-japonica hybrid rice variety Yongyou 7872 as the experimental material,the effects of different fertilization rates and methods on its yield and rice quality were studied. 6 different slow-release fertilizer treatments were set up. The results showed that under the transplanting density of 30cm x 18cm,the application of slow-release fertilizer as the base fertilizer of 540 kg/hm2,the application of u-rea of 156 kg/hm2 and potassium chloride of 75kg/hm2 at the panicle stage could ensure the high yield and good comprehensive quality of rice,and was significantly superior to the group without topdressing at the panicle stage.
