[目的]筛选适宜黔北烟区烤烟生产的适宜配方复合肥料.[方法]采用3点大田试验,研究3种新配方复合肥配施有机肥对烤烟经济性状、评吸质量、株型及化学成分协调性等指标的影响.[结果]施用T1(N:P2O5:K2O为10:12:24)和T2(N:P2O5:K2O为10:10:24)2种新配方复合肥料烤烟的评吸质量分别较对照(常规复合肥)提高了1.35和2.55分,产值分别提高了16.08%和4.73%;T2处理能改善株型,但烟叶的化学成分协调性欠佳.T3(N:P2O5:K2O为10:8:24)处理的经济性状、化学成分和评吸质量较对照略有降低,3种新配方复合肥对烤烟产质量改善的综合作用效果由优到劣依次为T1、T2、CK、T3.[结论]N:P2O5:K2O为10:12:24和10:10:24 2种新配方复合肥配施有机肥能有效提高烟叶的评吸质量和内在质量,增加经济效益.
[Objective]To select a suitable compound fertilizer in tobacco cultivation areas in North Guizhou.[Method]3 kinds of new formula compound fertilizer were applied with organic fertilizer,effects of new formula compound fertilizer with organic fertilizer on economic characters and sensory evaluation quality and chemical composition coordination of flue-cured tobacco by field test were studied.[Result]The smoking quality of T1 (nutrient ratio of N:P2O5:K2O was 10:12:24) and T2 (10:10:24) new formulation compound fertilizer of tobacco were increased by 1.35 and 2.55 score respectively,the output value were increased by 16.08% and 4.73%;T2 treatment could improve the plant type,but the coordination of chemical components was poor.The economic characters,chemical components and smoking quality of T3 (N:P2O5:K2O was 10:8:24)treatment were slightly lower than those of the control.And the effect of 3 kinds of compound fertilizers on the yield and quality of flue-cured tobacco was T1 > T2 > CK > T3.[Conclusion] Two new formulations of compound fertilizer of 10:12:24 and 10:10:24(N:P2O5:K2O) combined with organic fertilizer can effectively improve the quality of tobacco smoking and internal quality,and increase the economic efficiency.
