Embodiment 1
[0033] Embodiment 1: the preparation of plant nutrient:
[0034] 1) Enzymolysis: Wash the fish skin with 0.2N hydrochloric acid, add lipase to degrease or soak the fish scales in 3 times the amount of water, add 50% industrial grade hydrochloric acid to react for 10 hours, wash the fish scales with water twice to remove ash, and adjust the pH to 7 .5 to 8.0, add 0.3% of the total amount of alkaline protease, enzymatically hydrolyze for 2 hours, and obtain a small molecule collagen peptide solution after filtration;
[0035] 2) Determination: the obtained small molecule collagen peptide solution is sampled and hydrolyzed to determine the type and molecular weight of amino acids;
[0036] Specific method: Weigh 1 ml of the sample solution, put it into a small ampule bottle, add 1 ml of 12mol / L hydrochloric acid into the bottle, and seal it on the blowtorch flame. Put the ampule bottle into the drying oven, hydrolyze at 110°C for 20 hours, pour the hydrolyzate in the ampule bott...
Embodiment 2
[0048] Embodiment 2: field application experiment
[0049] 1) spray (apple)
[0050] The test plant nutrient agent was sprayed with 1000-1500 times of liquid in the apple flowering stage, fruit setting stage, young fruit stage, and fruit expansion stage. The control groups were conventional amino acid foliar fertilizer and blank control. The statistical analysis of the test results showed that: Not only the coloring rate and fruit grade of the plant nutrition agent are greatly improved, but also the yield is increased by 10% and nearly 50% respectively compared with other fertilizers and the blank control group.
[0051] 2) Spray (celery)
[0052] The test plant nutrients were sprayed at the seedling stage, growth stage, and harvest stage with 1000-1200 times of liquid respectively, and the control groups were conventional foliar fertilizer and blank control respectively. The statistical analysis of the test results showed that: Compared with the latter two cases, the yield ...
