生物炭与氮肥配施对米粉稻产量与稻米品质的影响
Effect of Combined Application of Biochar and Nitrogen Fertilizer on Yield and Quality of Rice in Noodles Rice
摘要
Abstract
In order to explore the effect of combined application of biochar and nitrogen feryilizer on the yield and quality of noodle rice,three treatments(without nitrogen fertilizer,CK;pure nitrogen 180 kg/hm2,T1;pure nitrogen 180 kg/hm2+biochar,T2)were set up to conducte a two-year field experiment with noodle rice variety Xiangzaoxian No.32 as material in Liuyang,Hunan.The results showed that nitrogen application treatment mainly achieved rice yield increase by signifi-cantly increasing the number of effective panicles,while combined application of biochar and nitrogen feryilizer further sig-nificantly increased yield by 7.92%-11.80%by increasing the number of effective panicles and seed setting rate.Combined application of biochar and nitrogen feryilizer treatment significantly improved the brown rice rate and milled rice rate,and reduced the chalky rice rate and chalkiness to a certain extent.Combined application of biochar and nitrogen fe-ryilizer treatment increased the content of amylose starch and protein components,especially the albumin content.Combined application of biochar and nitrogen feryilizer treatment reduced the peak viscosity,minimum viscosity and final viscosity of rice starch,but had no significant effect at the peak viscosity time and gelatinization temperature,and improved the viscosi-ty characteristics of noodle rice as a whole.It can be seen that biochar application treatment has better effect on the yield and quality of noodle rice.关键词
