有机钾肥及氨基酸络合微肥对烤烟产质效应的影响

Influence of Organo-Potash Fertilizers and Amino Acid-Complexed Micronutrient Fertilizers on Yield and Quality Effect of Flue-Cured Tobacco

研究了有机钾肥分别作为基肥和叶面肥和以含稀土的氨基酸微肥作为叶面肥对烟株的植物学性状、光合作用的影响以及对烟叶产量、产值和品质的影响。试验结果表明 :当以有机钾肥作为基肥 ,并在生育期和成熟期内分别喷施有机钾肥和含稀土的氨基酸微肥作为叶面肥时 ,烟叶的产量、产值可增加 10 %以上 ,烟叶中钾含量及烟叶品质均可得到明显的改善。

A study is made of the influence of organo-potash fertilizers as base manures and for foliar dressing and amino-acid micronutrient fertilizers with rare earth elements for foliage dressing on the phytological properties and photosynthesis of the tobacco plant and the yield, output value and quality of the tobacco leaves. The experimental results indicate that, when organo-potash fertilizers are used as base manure and are sprayed as foliar fertilizers during vegetation and amino-acid micronutrient fertilizers with rare earth elements are used for foliar dressing during maturity, the yield and output value of the tobacco leaves can be increased by over 10%, and the potassium content and quality of the leaves are greatly improved.
