探讨不同氮磷钾施用量对烤烟红花大金元产量和品质的影响,为凉山烟区红花大金元的进一步推广示范提供科学依据。试验设N1(60kg/hm2)、N2(82.5kg/hm2)、N3(105kg/hm2)3个处理水平,采用正交L9(34)设计,田间调查了各处理烟叶的农艺性状、主要经济性状和质量。结果表明,各处理的产量、产值、均价、上等烟比例和上中等烟比例均有显著差异,处理N(82.5)P(105)K(210)的经济性状较好,烟叶化学成分较适宜,烟叶评吸最好。凉山烟区土壤中等肥力下红花大金元的氮磷钾最佳施用量为N:P:K=82.5:105:210。
The effects of different NPK rates on the yield and quality of flue-cured safflower Daikin were explored to provide a scientific basis for further promotion and demonstration of safflower Dajinyuan in Liangshan. Three treatment levels, N1 (60kg / hm2), N2 (82.5kg / hm2) and N3 (105kg / hm2), were set up and the orthogonal L9 (34) design was used to study the agronomic characters and main economic traits And quality. The results showed that there was a significant difference in yield, output value, average price, superior tobacco ratio and upper middle tobacco ratio among all treatments. The economic traits of N (82.5) P (105) K (210) Appropriate, smoking the best tobacco. The optimal N, P, K = 82.5: 105: 210 for N, P, K fertilizer under medium fertility of soil in Liangshan tobacco growing area.
