摘要
为提高湖南稻茬烤烟氮肥利用率,增加烤烟产量,改善烟叶品质,以云烟87为材料,采用大田试验研究不同基追氮肥比例对稻茬烤烟生长、产量和质量的影响。结果表明:较低的基肥氮比例有利于烤烟前期生长和中、下部烟叶发育,可促进烟株干物质积累,提高烟叶干物质分配比例,增加中、下部烟叶烤后单叶质量,从而提高烤烟产量和产值。同时,较低的基肥氮比例有利于提高下部烟叶糖含量和上部烟叶钾含量。综合考虑烤烟产量、产值及品质等因素,本试验条件下稻茬烟区的最佳基追氮肥比例为2∶8。
In order to improve nitrogen use efficiency,yield and quality of flue-cured tobacco in rice stubble area of Hunan Province,Yunyan 87 was used as material to study the effects of different ratio of basal and topdressing nitrogen on the growth,yield and quality of flue-cured tobacco.The results showed that the lower base fertilizer nitrogen ratio was beneficial to the early growth of flue-cured tobacco and the development of middle and lower tobacco leaves,promoted the dry matter accumulation of tobacco plants,increased the dry matter distribution ratio of tobacco leaves,increased the single leaf weight of the middle and lower tobacco leaves after curing,thereby increased the yield and output value of flue-cured to-bacco.The lower basal fertilizer nitrogen ratio was beneficial to increase the sugar content of the lower tobacco leaves and the potassium content of the upper tobacco leaves.Considering the yield,output value and quality of flue-cured tobacco,the best ratio of base and topdressing nitrogen was 2∶8 of flue-cured tobacco in rice stubble area of Hunan Province.
