不同施肥量和施肥方式对甬优 7872 产量和稻米品质的影响.

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 30 cm x 18 cm, the application of slow-release fertilizer as the base fertilizer of 540 kg / hm², the application of urea of 156 kg / hm² and potassium chloride of 75 kg / 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.
