新型有机无机复混肥对烤烟部分生理指标的影响

Effect of a New Type Organic-mineral Complex Fertilizers on Several Physiological Indices of Flue-cured Tobacco

以烤烟品种K326为材料，在大田条件下研究了新型有机无机复混肥对叶片光合色素含量、超氧化物歧化酶（SOD）活性、硝酸还原酶（NR）等生理指标的影响。结果表明：施用新型有机无机复混肥合纯N6．5～7．5kg／667m^2时，烤烟光合色素总量和各色素的比例、SOD活性和NR活性均在一个较好的水平，对烤烟生长发育和良好品质的形成有好的作用，对烤烟生产具有指导意义。

The effects of a new type organic-mineral complex fertilizers on some physiological indices such as the contents of photosynthetic pigment, the activity of superoxide dismutase（SOD）, and the activity of NR were studied with the cultivar K326 under farm experiment. The resuhs showed that under the condition of a new type organic-mineral complex fertilizers in the lever of N 6.5 - 7.5 kg/667 m^2, the contents of photosynthetic pigment and the proportional of every photosynthetic pigment, the activity of SOD, and the activity of NR, both on a better level, is good to growth and better quality of flue-cured tobacco, and it has a signification of guidance to farm yield.
