摘  要:
为选择合理的烤烟控制灌溉模式,提高烟叶品质,在烤烟伸根期、旺长期、成熟期3个生育阶段进行灌溉控制,设计不同控制灌溉模式,并对所生产的烟叶品质进行测定,采用投影寻踪技术对各模式进行评价。结果表明:N5模式[60%(伸根期)-80%(旺长期)-60%(成熟期)]为最优控制灌溉设计;成熟期60%的控水设计,有利于烤烟品质的提高;N5模式所产烟叶的烟碱、还原糖、钾含量以及氮碱比、钾氯比均处于国家烟草专卖局给出的化学成分适宜范围,相比其他处理,烟叶品质更优。

摘  要:
In order to select the reasonable irrigation control pattern and improve the tobacco qua-lity,different irrigation control patterns were designed during the growth period of root extending,vigorous growth,and maturity.The indexes of tobacco quality were determined and the projection pursuit model was introduced for the assessment of irrigation control patterns.Results showed that:N5(60%-80%-60%,lower limit of root-extending stage,vigorous growth stage and maturity stage) was the optimal irrigation control pattern;the irrigation control design of 60% water during the maturity period was beneficial for the improvement of tobacco quality;among the chemical components of tobacco in N5 pattern,the nicotine content,reducing sugar content,potassium content,nitrogen/alkali ratio and potassium/chloride ratio were in the reasonable scope which was formulated by the State Tobacco Monopoly,in comparison with the other treatments,indicating a more reasonable and tobacco-preferable irrigation control pattern.
