| 摘 要： | 以水稻品种吉粳88为试验材料,采用裂区试验设计,研究了秸秆还田与氮肥运筹对东北稻区水稻产量及稻米品质的影响。结果表明,与秸秆不还田处理相比,秸秆还田降低了稻米糙米率、精米率、整精米率、垩白粒率、垩白度和直链淀粉含量,提高了稻米蛋白质含量;与秸秆不还田条件下最佳氮肥运筹处理相比,秸秆还田条件下的最佳氮肥运筹处理产量分别提高7.50%（2018年）和11.63%（2019年）;随基肥氮占比的下降,稻米糙米率、精米率、整精米率呈先上升后降低的趋势,垩白粒率、垩白度、直链淀粉含量呈下降趋势,蛋白质含量呈上升趋势。综合来看,在秸秆还田条件下,配以基肥:蘖肥:穗肥为6:3:1的氮肥运筹模式可以保证水稻产量的同时改善稻米加工品质和外观品质。

| Abstract: | A split-zone design experiment was used to study the effects of straw returning and nitrogen fertilizer management on yield and quality of rice variety Jigeng 88 in 2018 and 2019. The results showed that, compared with the treatment of not returning straw to the field, returning straw to the field reduced the rice brown rice rate, polished rice rate, whole rice rate, chalky grain rate, chalkiness and amylose content, and increased rice protein content. Compared with the optimal nitrogen fertilizer treatment （base fertilizer : tiller fertilizer : ear fertilizer is 5:3:2）under the condition of not returning straw to the field, the rice yield of the optimal nitrogen fertilizer treatment （base fertilizer : tiller fertilizer : ear fertilizer is 7:2:1） under the condition of straw returning to the field increased by 7.50% （2018） and 11.63% （2019）, respectively. With the decreased of the proportion of basal fertilizer in the total nitrogen application rate, rice brown rice rate, polished rice rate, and whole rice rate showed a trend of increasing first and then decreasing; chalky grain rate, chalkiness, and amylose content showed a decreasing trend, and protein content showed an increasing trend. On the whole, under the condition of returning straw to the field, combined with a 6:3:1 nitrogen fertilizer operation model of basal fertilizer : tiller fertilizer : panicle fertilizer could ensure rice yield while improving rice processing and appearance quality. |
