| 摘 要： | 以尿素、硫酸铵和硝酸钙为氮源,分别在基肥和追肥中选择不同氮肥施用,确定不同氮肥配施对马铃薯块茎形成和发育的影响。结果表明,与单施尿素相比,配施硫酸铵或硝酸钙可不同程度促进块茎形成和发育。其中,硫酸铵作基肥施用块茎总产量分别增加16.7%(2016年)和33.5%(2017年)(P0.05),商品薯产量增加20.1%(2016年)和40.7%(2017年)(P0.05);而硝酸钙作追肥施用块茎总产量增加10.4%(2016年)和26.2%(2017年)(P0.05),商品薯产量增加15.0%(2016年)和32.8%(2017年)(P0.05)。

| Abstract: | Urea, ammonium sulfate and calcium nitrate were used as start fertilizers or dressing fertilizers to study the influence of different fertilizer combinations on the formation and development of potato tuber. The results showed that compared with using urea only, both ammonium sulfate and calcium nitrate could facilitate the formation and development of tuber in varying degrees, and the treatment applied with ammonium sulfate as start fertilizer achieved increasements of the total tuber yield by 16.7% (2016) and 33.5% (2017) (P＜0.05) and commercial tuber yield by 20.1% (2016) and 40.7% (2017) (P＜0.05), while the treatment applied with calcium nitrate as dressing fertilizers got increasements of the total tuber yield by 10.4% (2016) and 26.2% (2017) (P＜0.05) and commercial tuber yield by 15.0% (2016) and 32.8% (2017) (P＜0.05). |
