Embodiment 1

[0016] Prepare the Jatropha extract powder first: select strong and lush Jatropha branches to cut the mouth and collect the pulp, store it at a temperature of 3-7°C for clarification for 24 hours within 6 hours, remove the lower layer of turbid liquid to obtain the Jatropha original pulp, and extract the Jatropha tree The puree was further concentrated at 60±10°C, and freeze-dried at -30±5°C to obtain Jatropha extract powder.

[0017] Preparation of jatropha-derived bacteriostatic agent: weigh and mix the ingredients according to the following weight percentages: 50% Jatropha extract powder, 8% osthole (90% white needle-shaped crystal powder), 37% Kaolin, 3% dispersant Morwet D-425 (sodium salt of alkylnaphthalenesulfonic acid polycondensate, Akzo Nobel), 2% wetting agent Morwet EFW (a combination of alkylnaphthalenesulfonate and anionic wetting agent mixture, AkzoNobel).

Embodiment 2

[0019] Prepare Jatropha Jatropha extract powder first: select strong and lush Jatropha Jatropha branches to incision and collect pulp, store at 3-7°C for clarification for 15 hours within 6 hours, remove the lower layer of turbid liquid to obtain Jatropha Jatropha original pulp, and extract Jatropha Jatropha The puree was further concentrated at 80±10°C, and freeze-dried at -25±5°C to obtain Jatropha extract powder.

[0020] Preparation of jatropha-derived bacteriostatic agent: weigh and mix the ingredients according to the following weight percentages: 58% Jatropha extract powder, 5% osthole (95% white needle-shaped crystal powder), 30.5% Kaolin, 5% dispersant Morwet D-425 (AkzoNobel), 1.5% wetting agent Morwet EFW (AkzoNobel).

Embodiment 3

[0022] Prepare the Jatropha Jatropha extract powder first: clean and disinfect the fresh Jatropha Jatropha leaves, then squeeze or crush them and add water to soak for 72 hours, then filter the filtrate and concentrate to obtain the water extract of Jatropha Jatropha leaves, put the water extract of Jatropha Jatropha leaves in Further concentrate at 70±10°C, freeze-dry at -35±5°C to obtain Jatropha extract powder.

[0023] Preparation of jatropha source bacteriostatic agent: weigh and mix the ingredients according to the following weight percentages: 42% Jatropha extract powder, 10% osthole (95% white needle crystal powder), 43% Kaolin, 2% dispersant Morwet D-425 (AkzoNobel), 3% wetting agent Morwet EFW (AkzoNobel).

Abstract

The invention discloses a bacteriostat from Jatropha curca, which contains Jatropha curcas extractive, wherein the Jatropha curcas extractive is prepared by using the method comprising the following steps: collecting syrup by choosing and cutting a strong luxuriant Jatropha curcas branch; preserving the syrup for 6 hours at 3-7 DEG C, and clarifying the syrup for 12-24 hours; taking the emulsion at lower layer, thereby acquiring original pulp of a Jatropha curcas tree; or washing and disinfecting fresh leaves of the Jatropha curcas tree; squeezing or smashing the leaves, adding water and soaking the leaves for 12-72 hours; and then filtering and concentrating the filtrate, thereby acquiring a water extract of Jatropha curcas leaves. The invention also discloses a bacteriostasis application of the bacteriostat in planting edible mushrooms. The bacteriostat from Jatropha curcas provided by the invention can be used for restraining fungus which is fostered by bacteria, has ultra-strong sterilization feature, and is characterized by full nutriments. The bacteriostat powder agent from Jatropha curcas which is scientifically prepared has excellent effect of restraining mildew and bacteria in planting edible mushrooms, is free from undesirable impact on the growth of fungus mycelium, and has excellent selective bacteriostasis.

Description

technical field [0001] The invention relates to a biological source bacteriostatic agent in the growth process of edible fungi, in particular to a jatropha source bacteriostatic agent and its bacteriostatic application in the cultivation of edible fungi. Background technique [0002] With the development of the edible fungi planting industry, some problems restricting the growth of edible fungi have also emerged. For example, most of the various edible fungi cultivated artificially belong to saprophytic fungi, and their growth substrates and cultivation conditions are also suitable for various types of fungi. The life of miscellaneous bacteria and some pests, and because the mycelium of edible fungi decomposes the matrix for nutrient transformation, the mycelium or fruiting body is full of nutrients such as special fragrance and high protein, which also makes many types of miscellaneous bacteria, especially molds Infecting the base material greatly damages the production of ...
