What will happen to kiwifruit due to nitrogen deficiency? Please introduce the nitrogen content of healthy new leaves of kiwifruit 2.2% Mel 2.8%.

The color of the leaves changed from dark green to light green, or even completely yellow, but the veins remained green. The apical edge of the old leaf was scorched and expanded to the base along the leaf vein, and the necrotic tissue curled slightly upward, sometimes accompanied by the phenomenon of smaller fruit.

Nitrogen fertilizer can be applied twice from the end of May to July, and 0.3% Mel 0.5% urea solution can also be sprayed on the leaves in the middle of growth for 2-3 times, each time at an interval of 7 days.
