Appropriate NH₄ ⁺/NO₃ ^- Ratio Triggers Plant Growth and Nutrient Uptake of Flowering Chinese Cabbage by Optimizing the pH Value of Nutrient Solution.

ABSTRACT: Compared with sole nitrogen (N), the nutrition mixture of ammonium (NH₄ ⁺) and nitrate (NO₃ ^-) is known to better improve crop yield and quality. However, the mechanism underlying this improvement remains unclear. In the present study, we analyzed the changes in nutrient solution composition, content of different N forms in plant tissues and exudates, and expression of plasma membrane (PM) H⁺-ATPase genes (HAs) under different NH₄ ⁺/NO₃ ^- ratios (0/100, 10/90, 25/75, 50/50 as control, T1, T2, and T3) in flowering Chinese cabbage. We observed that compared with the control, T1 and T2 increased the economical yield of flowering Chinese cabbage by 1.26- and 1.54-fold, respectively, wherea
