I. Purpose of the experiment
To verify the effect of polyglutamic acid on vegetables through the fertilizer efficiency test on greenhouseedible amaranth plant. To provide a basis for guiding scientific fertilization.
Contents of the experiment
1.To study the effect of polyglutamic acid in edible amaranth plant.
Experimental design
The experiment set up 2 treatments. The base fertilizer was applied uniformly. The fertilizer treatments were as follows:
T1: Control 60kg of basic fertilizer;
T2: base fertilizer 60kg + polyglutamic acid (20g flush);
IV. Experimental implementation
1、Test site: Puhao Ecological Park.
2、Crop for trial: edible amaranth plant
3、test plot setting: each treatment plot area of about 120 square meter
4、 fertilization and field management:
The base fertilizer was uniformly spread and tilled, and the treatment started when the seedling height was 5-6cm to flush with water; the management was consistent with the daily management.
V. Results and analysis



edible amaranth plant overall uniform growth, fat foliage, strong plants, few pests and diseases.

VI. Conclusion
Liyoung γ-PGA the main effect performance of the flushing fertilizer:
1、Edible amaranth plant plants are high, vigorous and high yield;
2、Edible amaranth plant leaves are fat, thick stems;
3、Edible amaranth plant root system is developed, root more, root long.
