摘要
进行了烟秆生物有机肥与化肥配施对烟叶生长及产量和质量的影响示范。结果表明,烟秆生物有机肥与化肥配合施用,与施用纯化肥相比,可以使上部叶提前成熟落黄,缩短白肋烟的大田生育期,而且更符合白肋烟的生长需肥规律,前期促进烟苗生长,后期促进烟叶的成熟。施用烟秆生物有机肥对烟株的长势无显著影响,但可以有效促进烟叶的生长,增大烟叶的面积。施用烟秆生物有机肥能有效增加白肋烟的抗病性,与对照相比,青枯病发病率降低了66.36%。施用烟秆生物有机肥能显著增加烟叶的产量,提高烟叶的品质,与对照相比,产量、产值、中等烟比例分别提高了7.48%、14.07%、11.72%。
The effect of combined application of tobacco stem biological organic fertilizer and chemical fertilizer on the growth,yield and quality of tobacco leaf were studied.The results showed that the combined fertilizer application pattern could promote the upper leaf maturity,shorten burley＇s field growth period,accord with the demand of tobacco on fertilizers well.This pattern could also promote tobacco growth in earlier stage and leaves maturity in later stage.The use of tobacco stem biological organic fertilizer had no significant influence on field growth,but could promote tobacco leaf growth and increase its area effectively.Compared with CK,the application of tobacco stem biological organic fertilizer could enhance the disease resistance of tobacco,as the bacterial wilt morbidity decreased by 66.36%.Besides,the production and quality of tobacco increased significantly when this organic fertilizer were used;The production,output and proportion of medium tobacco increased by 7.48%,14.07% and 11.72% respectively.
