    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。

    Abstract:

    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.
