Problems solved by technology

[0002] With the reduction of land area available for planting and the continuous growth of people's demand for materials, it is more and more urgent to improve the land utilization rate and increase the crop yield per unit planting land area. Among them, the large-scale use of chemical fertilizers and pesticides is a relatively It is a common way to increase and ensure crop yield, but it also brings some outstanding problems, such as soil compaction and pollution, pesticide residues, etc., which endanger people's health and the sustainable development of the ecosystem. Therefore, plant growth promoters are used to promote the growth of plants. The use of pathways such as growing to increase crop yields is increasingly common

Embodiment 1

[0030] 1. Test sample preparation

[0031] Plant growth promoter 1-1 preparation:

[0032] (1) After freezing the 5-10-day-old black soldier fly larvae cleaned with water at -15°C for 24 hours, crushing the frozen black soldier fly larvae and thawing to obtain black soldier fly meat paste;

[0033] (2) adding water to dilute the black soldier fly meat paste and then heating to 95-100° C. to ripen the black soldier fly meat paste; the quality of adding water is 28% of the quality of the black soldier fly meat paste;

[0034] (3) Cool down the matured black soldier fly meat paste dilution to 55°C, add biological enzymes to enzymolyze the black soldier fly meat paste for 3 hours, then raise the temperature of the enzymatically hydrolyzed black soldier fly meat paste to 98°C and keep it for 13 minutes to inactivate the biological enzymes to obtain the black soldier fly enzymatic hydrolyzate; the added amount of the biological enzymes is 0.2% of the mass of the black soldier fly m...

Embodiment 2

[0048] 1. Test sample preparation

[0049] Plant growth promoter 2-1 preparation:

[0050] (1) After freezing the 5-10-day-old black soldier fly larvae cleaned with water at -10°C for 24 hours, crushing the frozen black soldier fly larvae and thawing to obtain black soldier fly meat paste;

[0051] (2) adding water to dilute the black soldier fly meat paste and then heating to 95-100° C. to ripen the black soldier fly meat paste; the quality of adding water is 25% of the quality of the black soldier fly meat paste;

[0052] (3) Cool down the aged black soldier fly meat paste dilution to 50°C, add biological enzymes to enzymolyze the black soldier fly meat paste for 2 hours, then raise the temperature of the enzymolyzed black soldier fly meat paste to 95°C and keep it for 15 minutes to inactivate the biological enzymes to obtain the black soldier fly enzymatic hydrolyzate; the added amount of the biological enzymes is 0.3% of the mass of the black soldier fly meat paste, and the...

Embodiment 3

[0067] 1. Test sample preparation

[0068] Plant growth promoter 3-1 preparation:

[0069] (1) After freezing the 5-10-day-old black soldier fly larvae cleaned with water at -20°C for 16 hours, crushing the frozen black soldier fly larvae and then thawing to obtain black soldier fly meat paste;

[0070] (2) adding water to dilute the black soldier fly meat paste and then heating to 95-100° C. to ripen the black soldier fly meat paste; the quality of adding water is 30% of the quality of the black soldier fly meat paste;

[0071] (3) Cool down the aged black soldier fly meat paste dilution to 60°C, add biological enzymes to enzymolyze the black soldier fly meat paste for 3 hours, then raise the temperature of the enzymatically hydrolyzed black soldier fly meat paste to 100°C and keep it for 10 minutes to inactivate the biological enzymes to obtain the black soldier fly enzymatic hydrolyzate; the added amount of the biological enzymes is 0.1% of the mass of the black soldier fl...

Abstract

The invention relates to the technical field of agriculture, and particularly discloses a preparation method of a plant growth promoter, which comprises the following steps: (1) freezing hermetia illucens larvae cleaned by water, crushing the frozen hermetia illucens larvae, and unfreezing to obtain hermetia illucens meat paste; (2) adding water to dilute the hermetia illucens meat paste, and cooking the hermetia illucens meat paste; (3) adding a biological enzyme to perform enzymolysis on the hermetia illucens meat paste for a specified period of time, and inactivating the biological enzyme to obtain hermetia illucens enzymatic hydrolysate; (4) grinding clean fresh plant of Draba nemorosa, and adding water for dilution to form a Draba nemorosa diluent; (5) adding a bio-enzyme to carry out enzymolysis on the diluent for a specified period of time, and inactivating the bio-enzyme to obtain a Draba nemorosa plant enzymatic hydrolysate; (6) filtering the Draba nemorosa plant enzymatic hydrolysate to obtain Draba nemorosa filtrate; and (7) mixing the Draba nemorosa filtrate and the hermetia illucens enzymatic hydrolysate to obtain the plant growth promoter. The preparation method of the plant growth promoter is high in raw material utilization rate, and the obtained plant growth promoter is green, environment-friendly, free of soil pollution, free of residual harm to human bodies and outstanding in plant growth promoting effect.
