Problems solved by technology

However, most of these early growth promoters use a single chemical component, which has a single function and poor effect. After being applied to the fruiting body of edible fungi, it is not easy to adsorb on the surface of the fruiting body, and the duration of effect is short.
Improper use can easily damage the growth of the fruiting bodies of edible fungi and cause high concentrations of certain heavy metals to remain in the fruiting bodies of edible fungi, reducing the quality of edible fungi and causing potential harm to consumers

Embodiment 1

[0009] Embodiment 1: preparation of solid edible fungus growth promoter

[0010] 1. Cut the dried astragalus into thin slices, crush them, add 300g of astragalus powder per kilogram of water, completely submerge the astragalus, boil on low heat for 1 hour, filter, collect the filtrate, and cool it for later use;

[0011] 2. Weigh 2 g of alginic acid, 8 g of fulvic acid, 0.1 g of EDTA-Na (sodium ethylenediamine tetraacetate), 0.8 g of borax, and 0.8 g of FeSO 4 0.1g, Na 2 Mo 2 o 4 0.1g, ZnSO 4 0.2g, LaSO 4 0.05g, CeSO 4 0.05g, mixed and crushed;

[0012] 3. Weigh KH 2 PO 4 1.5g, chitosan 0.5g, gibberellin 1g, ammonium polyphosphate 1.5g, vitamin B group 0.5g, mixed and crushed;

[0013] 4. Measure 50mL of astragalus extract, mix all the above solid powder and liquid thoroughly, dry in the air, pulverize, pass through 200-300 mesh, and obtain 16.87g of the product.

Embodiment 2

[0014] Embodiment 2: the production of liquid edible fungus growth accelerator

[0015] 1. Cut the dried astragalus into thin slices, crush them, add 400g of astragalus powder per kilogram of water, completely submerge the astragalus, boil on low heat for 1 hour, filter, collect the filtrate, and cool it for later use;

[0016] 1. Weigh 2.5g of alginic acid, 15g of fulvic acid, 0.5g of EDTA-Na (sodium ethylenediaminetetraacetate), 0.8g of borax, FeSO 4 0.8g, Na 2 Mo 2 o 4 0.3g, ZnSO 4 0.6g, LaSO 4 0.5g, CeSO 4 0.3g, mixed and crushed;

[0017] 2. Weigh KH 2 PO 4 1.5g, chitosan 1g, gibberellin 2g, ammonium polyphosphate 1.2g, vitamin B family 1.2g, mixed and crushed;

[0018] 3. Measure 150mL of astragalus extract, thoroughly mix all the above-mentioned solid powder and liquid, and dissolve in 1500-2000mL of water to obtain a liquid product.

Embodiment 3

[0019] Example 3: Product application effect

[0020] 1. Application of the invented product (solid) in the production of Pleurotus ostreatus

[0021] Produce bagged oyster mushrooms in the laboratory, each bag is filled with 1000g, sterilized at 121°C for 45 minutes, cooled to 30-32°C, inoculated with oyster mushroom strains, cultured at room temperature, and after white dot-shaped fruiting bodies grow, 1g of the above-mentioned invention product solid powder is diluted with water, and is prepared into 0, 25, 50, 100, 200, 400, 800mg / L concentration respectively, sprayed on the fruiting body of Pleurotus ostreatus, investigate the growth status of Pleurotus ostreatus 10 days after spraying, Harvesting, each bag of fresh mushrooms (mature fruiting bodies) has a maximum weight gain of 45.8% ( figure 1 ), the surface of the fruiting body is white and smooth, hypertrophic, tall and straight, and grows vigorously.

Abstract

The invention relates to a method for preparing a growth promoter for edible fungi and application thereof. The method comprises the following steps of: dissolving, complexing, drying, mixing, and smashing the following components of raidx astragali leaching liquor, alginic acid, EDTA-Na, chitosan, fulvic acid, gibberellin, FeSO4, Zn SO4, LaSO4, CeSO4, KH2PO4, borax, Na2Mo2O4, ammonium polyphosphate, vitamins of B family and the like to obtain a mixture. The mixture has the advantages of rapid promotion of the edible fungi growth, enlargement of the fruiting bodies, accelerated growth, high performance of degrading and utilizing nutrients, improvement on stress resistance and disease resistance, yield increase, quality improvement, and nutrient value enhancement after the mixture is sprayed on fruiting bodies of the edible fungi.

Description

1. Technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a preparation method and application of an edible fungus growth promoter. 2. Background technology [0002] The traditional way of growing edible fungi is to use various discarded agricultural and sideline products to inoculate edible fungus strains for artificial cultivation. The growth rate is slow, the output is low, and the input-output ratio is small. Although some growth promoters have been developed and applied, these edible fungus growth promoters (solid or liquid) can be quickly absorbed and utilized by the edible fungus fruit bodies after spraying them with water to promote the growth of the fruit bodies and improve nutrient utilization. Rate. However, most of these early growth promoters use a single chemical component, which has a single function and poor effect. After being applied to the fruiting body of edible fungi, it is not easy to adsorb on ...
