摘要
[目的]进一步提高豫南温暖湿润区烤烟的产量和质量。[方法]以当地主栽品种云烟85为试验材料,设置6个试验处理进行烤烟专用微生物有机肥大田肥效对照试验,分析不同处理对烟株植物学性状和烟叶经济性状的影响。[结果]结果表明,烤烟专用微生物有机肥的施用量与大田不同时期烟株的各项植物学性状呈正比。营养生长期,大田烟株个体营养趋于协调,田间整齐度明显提高,叶片油润度增加。成熟期,烟叶表现集中成熟,部位间分层落黄好,鲜烟叶成熟度提高,烘烤特性改善。该试验条件下,微生物有机肥较常规施肥处理的烟叶产量和产值最高可增加11.17%和16.80%,增产、增值作用明显。[结论]烤烟专用微生物有机肥与无机复合肥配合施用,能够满足烤烟大田生育期的营养需要。
[Objective] The purpose was to enhance output and quality of the flue-cured tobacco of the south Henan warm moist area.[Method] With the local varieties Yunyan 85 as the trial materials,six treatments were mounted to study the microorganism organic fertilizer efficiency and analyze the effect of different treatment on botany traits of tobacco plant and economic character of tobacco leaf.[Result]The results indicated that employment quantity of the flue-cured tobacco special-purpose microorganism organic fertilizer and each botany traits of tobacco plant in the different period was proportional.The individual nutrition of tobacco plant tended to be coordinated,the field uniformity degree enhanced distinctly and the leaf blade smoothness increased in the nutrition vegetal period.The tobacco leaf was mature,the inter-layered site was yellow,the maturity of fresh tobacco leaf enhanced,roasting characteristic was improved in the mature period.Under this test condition,tobacco leaf output and the production valu
e which compared the convention to apply fertilizer processing might increase 11.17% and 16.80%,the function of the production increase and increment was obvious.[Conclusion] Coordinate employment of the flue-cured tobacco special-purpose microorganism organic fertilizer and the inorganic compound fat can satisfy the nutrition need of the flue-cured tobacco big field growth period.
