摘要: 通过不同地点的同一田块水稻的同一生育时期选择3种不同类型硒肥进行叶面喷施处理,以清水处理作为对照(CK),考察不同类型硒肥对水稻富集硒的差异。结果表明,通过富硒微生物将亚硒酸钠转化而成的华龙西科生物有机硒肥(处理3、处理4)效果最好,稻米总硒和有机硒含量为0.3~0.5 mg/kg,达到DBS42/002-2014要求,不同地点、不同品种稳定性好且成本较低;处理1施用的是农希科牌硒肥,稻米总硒和有机硒含量不稳定,在0.15 mg/kg以下,或在0.5 mg/kg以上,达不到DBS42/002-2014要求;处理2施用的是硒之源牌硒肥,稻米总硒在0.15 mg/kg以下,且有机硒占比未达到80%,达不到DBS42/002-2014要求。

Abstract: Three different types of selenium fertilizers were selected for leaf spraying treatment at the same growth stage of the same field of rice in different locations. The clean water treatment was used as control (CK) to investigate the difference of different types of selenium fertilizers on selenium enrichment in rice. The results showed that the Hualongxike brand bio-organic selenium fertilizer (treatment 3 and treatment 4) transformed by selenium-enriched microorganisms sodium selenite had the best effect, and the total selenium and organic selenium content of rice reached 0.3~0.5 mg/kg accurately, meeting the requirements of DBS42/002-2014, good stability and low cost in different locations and different varieties; Treatment 1 application was Nongxike brand selenium fertilizer, the total selenium and organic selenium content of rice was unstable, some points were below 0.15 mg/kg, and some points were above 0.5 mg/kg, which could not reach DBS42/002-2014 requirements; Treatment 2 applied selenium fertilizer of Xizhiyuan brand. The total selenium in rice was below 0.15 mg/kg, and the proportion of organic selenium was less than 80%, which could not meet the requirements of DBS42/002-2014.
