摘要
在大田条件下,研究了喷施低(0.67 mL/L)、中(1.33 mL/L)、高(2.00 mL/L)三种浓度富硒有机水溶肥料对冬小麦硒含量、生物量、硒累积量及籽粒产量质量的影响。结果表明:(1)冬小麦各部位硒含量总体上表现为根>茎叶>穗,硒累积量均以茎叶为最高。(2)喷施富硒有机水溶肥料可提高冬小麦各部位硒含量、硒累积量,但对各部位干重影响不尽一致;随着喷施浓度由低至高,冬小麦根硒含量、硒累积量均呈先增加后降低趋势,茎叶硒含量、硒累积量均呈先降低后增加趋势,穗硒含量、硒累积量均呈逐步增加趋势。(3)喷施富硒有机水溶肥料可提高冬小麦产量、穗数、穗粒数及千粒重,但对籽粒粗蛋白、粗纤维、面筋质、脂肪及硒含量的影响不同;喷施中浓度富硒有机水溶肥料对冬小麦产量、千粒重及籽粒硒含量的提高较为明显,增幅依次为8.4%、6.2%、240.0%。(4)喷施中浓度富硒有机水溶肥料总体增产提质效果最好,达到富硒冬小麦要求。
The effects of spraying low(0.67 mL/L),medium(1.33 mL/L)and high(2.00 mL/L)level selenium-enriched organic water-soluble fertilizer on selenium content,dry weight,selenium accumulation and yield,quality in wheat were investigated under field conditions.The results showed that:(1)The selenium content order was root>stem and leaf>spike,the selenium accumulation in stem and leaf was the highest.(2)Spraying selenium-enriched organic water-soluble fertilizer could increase the selenium content,selenium accumulation in each organ,but had different influences on dry weight;with the increase level of selenium-enriched organic water soluble fertilizer,the selenium content,selenium accumulation increased first and then decreased in root,decreased first and then increased in stem and leaf,showed a upward trend in spike.(3)Spraying selenium-enriched organic water-soluble fertilizer could increase the yield,number of spike,grains per spike,1000-grain weight,but had different influences on crude protein,crude fiber,wet gluten,fat,Se content;spraying medium level Selenium-enriched organic watersoluble fertilizer had a better effect on yield,1000-grain weight,Se content,the increasing ranges were 8.4%,6.2%,240.0%,respectively.(4)Spraying medium level selenium-enriched organic water-soluble fertilizer had the best effects on yield and quality,met the standard of selenium-enriched wheat.
