摘要

针对陇东旱塬烤烟生产中存在的氮肥种类选择不合理引起的产量不高、品质下降等问题

于2009年在甘肃省庆阳市正宁县进行大田试验

研究不同形态氮肥硝铵磷(ANP)和尿素(UA)对烤烟产量形成的作用及其机理。结果表明:ANP处理显著促进了烤烟根系的生长发育

增强了烤烟根系活力

比UA处理具有更理想的根参数和更强的根系活力

移栽15 d后

ANP处理的总根长、表面积、根尖数和根系活力分别比UA处理的增加了63.4%

64.3%

54.3%和43.8%;ANP处理显著提高了根系和地上部干物质积累量

表现在收获时ANP处理的根系及地上部干物质积累量分别比UA处理的增加了15.87%和12.05%;烤烟移栽后短期内

ANP处理的土壤NO3--N含量明显高于UA处理的

且土壤NH4+-N含量明显低于UA处理的

移栽5 d后

ANP处理的土壤NO3--N含量比UA处理的增加了44.7%

NH4+-N含量比UA处理的降低了44.8%;ANP处理显著提高了烤烟产量和产值

分别比UA处理增加了16.8%和24.8%

纯收入增加了7 330元/hm2;尿素和硝铵磷施入土壤后短期内化学行为的不同

以及由此引起的根形态和吸收能力不同是引起烤...

Abstract

Aimed at dealing with the serious problems brought about by irrational fertilization which detered the growth

yield and quality of flue-cured tobacco in Loess Plateau of east Gansu province

the present research had probed into the effects of different nitrogen fertilizers(ANP and UA) on yield formation of the flue-cured tobacco and its mechanisms

in 2009 in Zhengning county

Gansu.The results showed that:ANP significantly promoted the growth of roots and enhanced the activities of roots.Compared with UA trea...
