摘要
为探讨生物有机硒对马铃薯产量和硒含量的调控效应,在不同马铃薯品种不同生育时期(块茎形成期和块茎增长期)叶面喷施生物有机硒营养液,研究其对马铃薯产量、地下块茎硒含量的影响以及不同马铃薯品种间差异。结果表明,施硒后马铃薯大中小薯个数均增加2.69%~17.72%,大薯率提高3.65%~3.79%,大中薯产量增加7.35%~26.17%,小区产量增加,且施硒2次比施硒1次的小区产量更高,增幅9.06%,折合3590.10 kg/hm^(2);随着施硒次数增加,马铃薯中总硒和有机硒含量均显著增加,相同处理不同品种间差异显著,且硒处理组马铃薯地下块茎硒含量均达到农业行业标准《富硒马铃薯》(NY/T3116—2017)规定的15~150μg/kg要求,为应用生物有机硒营养液生产高产富硒马铃薯配套栽培技术的制定提供了理论依据。
In order to explore the regulatory effects of bio-organic selenium on potato yield and selenium content,the bio-organic selenium nutrient solution was sprayed on the leaves of different potato varieties at different growth stages(tuber formation stage and tuber growth stage),and its effects on potato yield,selenium content in underground tubers and differences among different potato varieties were studied.The results showed that after selenium application,the number of large,medium and small potatoes increased(2.69%-17.72%),the rate of large potatoes increased by 3.65%-3.79%,the yield of large and medium potatoes increased(7.35%-26.17%),the plotyield increased,and the plot yield of potatoes with two selenium applicationwas higher than that with one,with an increase of9.06%,equivalent to 3590.10 kg/hm^(2);with the increase in the number of selenium applications,the content of total selenium and organic selenium in potatoes both increased significantly.There were significant differences between different varieties of the same treatment,and the selenium content of underground tubers of the selenium treatment group potato met the requirements of 15-150μg/kg specified in the agricultural industry standard"Selenium-enriched Potatoes"(NY/T 3116-2017),which provided theoretical basisfor the development of supporting cultivation techniques for the production of high-yield selenium-enriched potatoes using bio-organic selenium nutrient solution.
