摘要
田间试验条件下研究化肥及其与不同比例绿肥配合施用对烤烟生长发育、产量和品质的影响。结果表明：烤烟遭遇严重干旱年份，生长受到严重抑制，不施肥时表现更明显，病害发生普遍，产量、产值显著降低。与单施化肥相比，绿肥与化肥不同比例配施均可明显提高烤烟株高、最大叶长、最大叶宽和茎围，降低青枯病、普通花叶病发生率，根、茎、叶各部位生物量明显增加。随着肥料用量中绿肥比例增加，烤烟产量和产值有逐渐增加趋势，翻压绿肥各处理产量、产值分别是单施化肥的1．16～1．71倍、1．09～2．16倍。与单施化肥相比，绿肥与化肥配施烤烟叶片烟碱含量提高，还原糖／烟碱值下降，下部叶和中部叶总氮／烟碱比值均明显下降，上部叶总氮／烟碱比值平均有增加趋势，不同部位叶片钾含量均明显提高，烤烟化学成分协调性增加。
A field experiment was carried out to study the effects of combining application of green manure and chemical fertilizer on the growth and development,yield and quality of flue-cured tobacco in dry year. The results showed that the growth of flue-cured tobacco was inhibited in the dry year, especially under no fertilizer applying. Meanwhile the disease of flue-cured tobacco severely occurred, the yield and output value were significantly decreased. In comparison with single chemical fertilizer,combination of. green manure and chemical fertilizer significantly increased the plant height, the length and width of the max leaf and stem circumference of flue-cured tobacco,decreased the incidence of granville wilt and tobacco mosaic virus, enhanced the dry weight of root, stem and leaves of flue-cured tobacco. The higher the percentage of green manure accounted for the total rate of fertilizer application, the higher was the yield and output value of the flue-cured tobacco. To compare with single chemical fertilizer application,the yield and output value of flue-cured tobacco that the green manure were applied were 1.16- 1.71 times and 1.09-2. 16 times, respectively. Combining application of green manure and chemical fertilizer increased the content of nicotine and potassium in all leaves, decreased the ratio of reducing sugar to nicotine in all leaves and the ratio of total nitrogen to nicotine in the middle and lower leaves,and improved the ratio of total nitrogen to nicotine in upper leaves of the flue-cured tobacco. These suggested that the harmony of the chemical component of flue-cured tobacco would be raised when green manure was ploughed in.
