摘要
为改善烤烟品质，提高肥料施用效益，进行了有机肥与化肥配比试验。试验表明，一定量的牛粪、菜籽饼或花生饼与化肥配施，可明显提高烤烟叶片中磷钾营养、根系氮素营养的分配比例，降低茎秆中氮磷钾分配比例。适量有机肥与化肥配施有利于提高烤烟中、上部叶的氮钾含量。试验结果还表明，当有机氮施肥比例占总施氮量的２５％时，烤烟生长良好，抗病性增强，烟叶适时落黄成熟，烟叶内在品质提高，上等烟比例提高３．６～９．１个百分点，每公顷产值增加３９１．９５～１１８６．１６元。说明适量有机肥与化肥配施，可明显提高烤烟叶片中磷、钾营养元素的含量，提高烟叶品质，增加产量，提高经济效益。
Combining application of
organicchemical fertilizers was studied to raise the yield and improve the quality of tabacco
leavesResults showed that combining application of cow dung,rapeseed cake or peanut cake
with chemical fertilizers could increase the distribution ratio of phosphorus and potassium in
the leaves and that of nitrogen in the roots,and decrease the distribution ratio of
nitrogen,phosphorus,potassium in the stems of tobaccoAs the applying amount of cow dung and
rapeseed cake increased the distribution of nitrogen in the leaves reducedCombining
application of organicchemical fertilizers could raise the concentrations of nitrogen,potassium
in middle and upper leavesAs the applying amount organicN was twentyfive percent of total
N,tobacco plants grew better,increased disease resistance,and leaves turn into yellow and
ripened in time,improved the quality of leaves,the ratio of qualified tobacco leaves was
increased by 36-96 point of percentage,and output value was increased by 39195-11861 .So
combining application of organicchemical fertilizers could improve the quality of leaves
