STUDY ON THE EFFECTS OF NPK FERTILIZER ON SOME PHYSIOLOGICAL AND BIOCHEMICAL PARAMETERS OF MANGLIETIA CONIFERA DANDY AT SEEDLING STAGE

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.
