不同有机肥对云烟99生长发育及产质量的影响

目的]探明秦巴烟区不同有机肥对烤烟生长发育及产质量的影响。方法]以云烟99为试验材料,通过田间试验,研究高碳基土壤修复一体肥、腐殖酸类有机肥与无机肥配合施用对其生育期、农艺性状、经济性状等的影响。结果]配施有机肥对云烟99农艺性状影响不显著;但有利于烟株早期及中期早发快长和成熟期落黄;能够提高烟株抗病能力,但抗病能力随有机肥比例的增加而下降;有机肥不能提高烟叶产量,但可以显著增加中上等烟叶比例。结论]配施有机肥可以改善烟叶质量,增加烟株抗病性,但是不能提高其产量。

Effects of Different Organic Fertilizers on the Growth,Yield and Quality of Yunyan 99

Objective] To discuss the effects of different organic fertilizers on the growth, yield and quality of flue-cured tobacco in Qinba To-bacco Growing Area. Method] With Yunyan 99 as the tested material, field experiment was carried out to research the effects of carbon based fertilizer soil remediation, humic acid organic fertilizer and inorganic fertilizer on the growth, agronomic characters and economic character.Re-sult] Organic fertilizer had no significant effects on agronomic characters of Yunyan 99, but was conductive to the early and mid-term early fast growth and to turn yellow in mature period.Organic fertilizer was able to improve the disease resistance of Yunyan 99, but the resistance dropped with the increase in the proportion of organic fertilizer.Organic fertilizer could not improve the yield of tobacco leaves, but significantly increased the first and second class tobacco proportion of Yunyan 99.Conclusion] Organic fertilizer improves the quality of tobacco leaves, enhances the disease resistance of tobacco plant, but can not enhance the yield of Yunyan 99.
