Effects of different types of organic fertilizers on rice yield and quality
In this study,a field plot experiment was conducted with Nanjing 46 as the test material.By setting no ni-trogen fertilizer,conventional chemical fertilizer,and organic manure(chicken manure,pig manure and sheep manure)instead of 50%chemical fertilizer as the base fertilizer,a total of five treatments were used to explore their effects on rice yield and rice quality.The results showed that compared with conventional chemical fertilizer treatment,50%sheep manure organic fertilizer treatment significantly reduced rice yield,but significantly increased the head rice rate and viscosity of rice,significantly reduced the chalkiness rate and chalkiness degree of rice,and significantly reduced the rice's hardness,impairment,recovery value,and peak time,so that the quality of rice was significantly improved.Compared with the con-ventional chemical fertilizer treatment,different types of organic fertilizers replacing chemical fertilizer basal application all reduced the protein content of rice and increased the gel consistency of rice.However,different organic fertilizer treatments did not significantly improve most of the rice quality indicators.In summary,applying different types of organic fertilizer in-stead of chemical fertilizer as base fertilizer could improve rice quality to different degrees,especially 50%sheep manure organic fertilizer treatment could improve rice quality more obviously,but the rice yield was reduced un-der this treatment.
