生物有机类肥料对‘云烟87’生长发育及烟叶产质量的影响

The Effects of Bio-organic Fertilizer on Growth and Yield and Quality of‘Yunyan 87’

为提高楚雄武定烟叶产质量,探索不同类型的生物有机类肥料对烟叶产质量的影响,在楚雄州武定县通过同田对比试验进行研究,研究腐植酸有机肥、功能微生物菌剂以及生物有机肥等不同种类生物有机类肥料对‘云烟87’生长发育及烟叶产质量的影响。结果表明,施用功能微生物菌剂、生物有机肥A、生物有机肥B的处理烟株提前2~3天进入旺长期,促进烟株早生快发;与常规施肥相比,施用腐植酸有机肥、生物有机肥A烟株封顶后株高分别提高3.57%、12.37%,单株叶片提高-7.73%、5.83%,中部最大叶面积提高-10.24%、21.46%;施用腐植酸有机肥、微生物菌剂和生物有机肥A产量分别提高12.50%、2.28%、14.82%,产值提高0.16%、-4.02%、30.13%,均价提高-10.96%、-6.13%、13.34%;施用生物有机肥可有效改善植烟土壤营养成分及土壤酸碱度,使其更利于烟株早生快发,促进烟株根系生长,改善烟叶品质,增强烟叶化学协调性,提高经济效益。

To improve the yield and quality of tobacco leaves in Wuding County of Chuxiong in Yunnan,and explore the effects of different types of bio-organic fertilizers on the yield and quality of tobacco leaves,a field comparative experiment was conducted to study the effects of humic acid organic fertilizer,functional microbial agent and bio-organic fertilizer on the growth and development of‘Yunyan 87’and the yield and quality of tobacco leaves.The results showed that the application of functional microbial agents,bio-organic fertilizer A and bio-organic fertilizer B could promote early and rapid growth of tobacco plants by 2-3 days.Compared with conventional fertilization,applying humic acid organic fertilizer and bio-organic fertilizer A increased the plant height by 3.57%and 12.37%,the leaf area per plant by-7.73%and 5.83%,and the maximum leaf area in the middle by-10.24%and 21.46%,respectively.Applying humic acid organic fertilizer,microbial agents and bio-organic fertilizer A increased the yield by 12.50%,2.28%and 14.82%,the output value by 0.16%,-4.02%and 30.13%,and the average price by-10.96%,-6.13%and 13.34%,respectively.The application of bio-organic fertilizer can effectively improve the nutrient composition and pH of tobacco planting soil for the early and rapid growth of tobacco plants,promote the root growth of tobacco plants,improve the quality of tobacco leaves,enhance the chemical coordination of tobacco leaves,and increase economic benefits.
