不同农家肥施用量对彭水烟区烟叶产质量的影响

目的]探明彭水烟区烟叶的最佳农家肥施用量。方法]2015年通过随机区组试验开展了不同农家肥用量对烟叶产质量的影响。结果]较对照而言,施用农家肥的各处理对烟叶外观质量总分影响较大,T3处理(施用农家肥2 250 kg/hm2)总体较优。各处理对化学成分的影响主要体现在中部叶两糖含量方面,其中T3处理(施用农家肥2 250 kg/hm2)、T4处理(施用农家肥3 000 kg/hm2)两糖含量较对照差异达到显著水平。产值以T3处理(施用农家肥2 250 kg/hm2)最高,较对照差异达到显著水平。结论]T3处理(施用农家肥2 250 kg/hm2)效果最佳,建议在彭水烟区烟叶生产中施加农家肥2 250~3 000 kg/hm2。

Effects of Farmyard Manure Dosage on Tobacco Leaf Quality of Pengshui Tobacco Area

Objective] To research the optimal farmyard manure dosage for tobacco leaf in Pengshui Tobacco Area.Method] Effects of farm-yard manure dosage on tobacco leaf quality were researched in 2015 by randomized block test. Result] Compared with the control, different treatments of applying farmyard manure had relatively great impacts on the appearance quality of tobacco leaf .And T3 treatment(2 250 kg/hm2 ) was better in general.The effects of treatments on chemical components were mainly reflected in total sugar and reducing sugar contents in middle leaves.Among them, total sugar and reducing sugar contents in T3 treatment(2 250 kg/hm2) and T4 treatment(3 000 kg/hm2) reached signifi-cant level compared with those in control.Output value in T3 treatment(2 250 kg/hm2 ) was relatively high, reaching significant level compared with the control.Conclusion] T3 treatment(2 250 kg/hm2) has the optimal effects.And 2 250 -3 000 kg/hm2 farmyard manure is suggested to be applied during production.
