Abstract

The paper presents the effects of NPK fertilizer on some physiological and biochemical indicators in the seedling stage of manglietia conifera grown in Lao Cai. The results showed that NPK with the appropriate content (0.5g/plant) had the effect of increasing a number of physiological and biochemical indicators such as leaf area, root mass, chlorophyll content, and the amount of vitamin C, total organic acid, reducing sugar content, free ammonium content and increasing the activity of the enzymes catalases, perozydases, thereby making plants grow and develop better.
Keywords: NPK fertilizer, physiological parameter, biochemical parameter, seedling.
