摘要:

本研究旨在探讨孕穗期外施不同用量硒肥对粳稻品种南粳9108和皖垦糯2号产量及稻米品质的影响。试验结果表明,孕穗期喷施硒肥能显著(p<0.05)提高稻米中的硒含量,并对水稻的产量和品质具有积极作用。相较于对照,2个水稻品种在喷施30和60 mL·hm-2硒肥后,产量均有所增加,其中南粳9108和皖垦糯2号在喷施60 mL·hm-2硒肥后分别增产2.25%和4.09%。此外,外施硒肥能有效提升水稻籽粒的灌浆速率、剑叶SPAD值、食味值和整精米率,同时降低垩白粒率和垩白度,改善稻米的加工品质和外观品质。研究结果为合理利用硒肥和提高稻米硒营养水平提供了理论依据。

Abstract:

This study was conducted to investigate the effects of different doses of selenium fertilizer applied at booting stage on the yield and rice quality of japonica rice varieties Nanjing 9108 and Wankennuo 2. The results showed that selenium fertilizer sprayed at booting stage could significantly (p<0.05) increase the content of selenium in rice,and had positive effects on the yield and quality of rice.Compared with the control,the yield of these two rice varieties increased after spraying 30 and 60 mL·hm-2 of selenium fertilizer,and the yield of Nanjing 9108 and Wankennuo 2 increased by 2.25% and 4.09%,respectively, after spraying 60 mL·hm-2 of selenium fertilizer. In addition,the application of selenium fertilizer could effectively improve the grain filling rate,SPAD value of flag leaf,taste value and head rice rate,and reduce chalky grain rate and chalkiness degree,and improve the processing quality and appearance quality of rice. The results provided theoretical basis for rational utilization of selenium fertilizer and improvement of selenium nutrition level of rice.
