摘要: 以豫花37为供试材料,采用盆栽试验,探讨了3种硒源(Na2SeO3、SeMet、SeCys)对花生农艺性状、花生植株各部位中硒含量、硒累积量、分配和产量构成的影响。结果表明,在同一施硒水平下,施入有机硒源(SeMet和SeCys)较无机硒源可以更好地促进植株的生长发育,增加主茎高、第一侧枝长和分枝数;花生植株各部位硒含量均表现为根部最高,其次为子粒,无机硒源对花生子粒硒含量及硒累积量高于有机硒源,植株各部位硒累积量高低均表现为子粒(5.40~16.75 μg/株)>叶(3.33~4.86 μg/株)>茎(2.11~3.47 μg/株)>壳(2.05~3.23 μg/株)>根(0.85~1.75 μg/株);硒积累量的分配比率均表现为子粒占比最大,根占比最小。有机硒源产量、百果重及单株饱果重均高于无机硒源(Na2SeO3),其中SeMet和SeCys处理花生产量较Na2SeO3处理显著增加22.5%、18.8%;土壤施入3种外源硒对花生的农艺性状、硒含量及累积量分配比例和产量构成均产生不同的影响。

Abstract: Using Yuhua 37 as the experimental material, a pot experiment was conducted to explore the effects of three selenium sources (Na2SeO3, SeMet and SeCys) on agronomic characters, selenium content, selenium accumulation, distribution and yield composition of peanut. The results showed that at the same level of selenium application, the application of organic selenium sources (SeMet and SeCys) could promote plant growth better than inorganic selenium sources, and increase the height of main stem, the length of first branch and the number of branches. The content of selenium in all parts of peanut plants was the highest in the roots, followed by kernels. The selenium content and selenium accumulation of peanut kernel from inorganic selenium sources on were higher than those from organic selenium sources. The order of selenium accumulation in different parts of the plant was as follows: Kernel(5.40~16.75 μg/plant)>leaf(3.33~4.86 μg/plant)>stem(2.11~3.47 μg/plant)>shell(2.05~3.23 μg/plant)>root (0.85~1.75 μg/plant). The distribution ratio of selenium accumulation showed that the proportion of kernel was the largest and that of root was the lowest. The yield, 100-pod weight and full pods weight per plant of organic selenium source were higher than those of inorganic selenium source (Na2SeO3), and the yield of SeMet and SeCys treatments increased significantly by 22.5% and 18.8% compared with Na2SeO3 treatment. Soil application of three kinds of exogenous selenium had different effects on agronomic characters, selenium content and cumulative distribution proportion and yield components of peanut.

Key words: different exogenous selenium, peanut, the content of selenium, distribution, yield
