I. Purpose of the experiment
    To verify the utility of polyglutamic acid on vegetables through the fertilizer efficiency test on greenhouse fruit cucumber. To provide a basis for guiding scientific fertilization.
Experimental content
1. Study the effect of polyglutamic acid on fruits and vegetables.
Experimental design
The experiment was set up with 2 treatments. The base fertilizer was applied evenly. The fertilizer treatments were as follows
T1: Control: 60 kg of basal fertilizer;
T2: base fertilizer 60 kg + polyglutamic acid (200 g) applied with water;
IV. Experimental implementation
Location: Puhao Ecological Garden.
2. Test crop: fruit cucumber
3. Fertilizer application and field management:
The base fertilizer was evenly spread and tilled, the flushing treatment was started when the seedlings were 5-6cm tall, and the management was the same as the daily management.
V. Results and analysis


Twelve days after fertilization treatment, fruit cucumbers in the treatment group were robust, with oily green leaves and significantly higher plant height than the control group.

The leaves of the treatment group were large and plump with clear veins and oily color.

Seven days after the fertilization treatment, the treated group flowered early and the control group remained unbloomed.

LiYoung polyglutamic acid fertilizer can promote early flowering and fruiting of crops and make fruit cucumbers available earlier.

Fruit cucumbers in the treatment group were observed in the same period, picking period was advanced and marketed 5-7 days earlier.
