中微肥的施用对云南砚山地区烟叶经济效益的影响研究

Effect of Fertilizer Application on the Economic Benefits of Tobacco in Yanshan Area of Yunnan Province

中微量元素是多种酶的成分或活化剂,参与碳素同化、碳水化合物转运、氮素代谢和氧化还原过程等,能促进植物生长发育,增强抗逆力。该试验根据砚山烟区土壤肥料缺乏程度和烟株营养需求,在施用氮、磷、钾肥的基础上,研究增施中微量元素肥料在烤烟生产中的增产效果。结果表明,增施中微量元素肥料的烟株根系发达、生长旺盛,适时落黄,烟叶增产、增质效果显著,经济效益明显。

Trace elements in a variety of enzymatic components or activators,participate in carbon assimilation,nitro-gen metabolism and carbohydrate transport and oxidation reduction process,can promote plant growth,increase resil-ience.According to the test of soil and fertilizer Yanshan tobacco deficiency and tobacco plant nutrient requirements,based on the application of nitrogen,phosphorus and potassium fertilizer,effects of application of trace elements fer-tilizer in tobacco production yield were studied.The results showed that the nitrogen fertilizer of trace elements in to-bacco roots developed,vigorous growth,timely yellow and increased production and quality of tobacco leaves,signifi-cant effect,obvious economic benefit.
