摘 要: | [目的]研究小麦秸秆碳氮比调控施用对烟叶氮磷钾吸收的影响.[方法]2008~2009夏种季节于云南省曲靖市板桥镇进行田间小区试验,探讨小麦秸秆及其碳氮比调控后施用对烤烟产量、产值及上、中、下部烟叶对氮、磷、钾含量及累积吸收量的影响.[结果]小麦秸秆无论单独施用,还是碳氮比调控后施用均能促进烟叶产量、产值显著提高,同时,烟叶钾含量、钾和氮的累积吸收量也均有显著增加,而且小麦秸秆进行碳氮比调控后施用更有利于烟叶钾的吸收.与不施用秸秆相比,小麦秸秆单独施用、小麦秸秆+苕子、小麦秸秆+油枯、小麦秸秆+尿素进行碳氮比调控后施用,烟叶产量分别提高6.59%、3.58%、5.98%、8.80%,烟叶钾含量分别提高3.85%、7.76%、8.82%、11.21%,烟叶钾的总累积量分别提高10.71%、11.62%,15.32%、21.01%,烟叶氮的总累积量分别提高9.76%、1.22%、8.14%、14.00%;而不同处理之间烟叶氮含量无显著差异,烟叶对磷的吸收降低.[结论]在烤烟生产中施用高碳氮比小麦秸秆,即要注意补充氮素调节碳氮比,也要考虑磷素的补充.Abstract:[Objective] The aim was to study the effects of regulation C/N ratio wheat straw application on tobacco nitrogen,phosphorus,and potassium uptake.[Method]Effects of regulation C/N ratio wheat straw application on the flue-cured tobacco yield,output value,nitrogen,phosphorus and potassium content and cumulative uptake of the upper,middle and bottom leaf were studied by using the field plot experiments at Banqiao town,Qujing City,Yunnan Province during the 2008-2009 summer growing seasons, [Result] The results showed that the application of wheat straw alone or after C/N regulation,could significantly increase tobacco production,potassium content,the potassium and nitrogen accumulation amount of leaf,and was more conducive to the potassium uptake of tobacco leaf with wheat straW application after C/N regulation.Compared with non-straw application,the yield of tobacco increased by6.59%,3.58%,5.98%,8.80%with application of wheat straw alone,wheat straw and vetch,wheat straw and oilseed cake,wheat straw and urea nitrogen,the potassium content in tobacco leaf increasod by 3.85%,7.76%,8.82%,11.21%,respectively,the total potassium cumulative amount of leat increased by 10.71%,11.62%,15.32%,21.01%and the total nitrogen cumulative amount increased by9.76%,1.22%,8.14%,14.00%.However,the differences of tobacco leaf nitrogen content between the different treatments were not significant,the phosphorus uptake of tobacco leaf decreased. [Conclusion] The application of high C/N ratio wheat straw in flue-cured tobacco production,which should be concerned not only to adjust C/N ratio by adding nitrogen,but also considering additional phosphorus application.
