Simple Method for Making Mother Culture Medium of Edible Mushrooms

Simple method for making the mother culture medium of edible fungi Mushroom farmer generally uses agar in preparing mother culture medium of edible fungi. However, the price of agar is relatively high, and it is not easily available in some regions, and the use of agar to solidify the medium is also a cumbersome process. For this reason, the author introduced the preparation methods of several kinds of simple mother-breeding media. Green bean powder medium. Put fresh, dry, mildew-free mung bean powder into the pot, add the appropriate amount of water to boil, turn it into a paste, and put it into a test tube. The loading amount is 1/4--1/3 of the test tube capacity, and then it is plugged. The tampon was sterilized under a pressure of 15 pounds for 45 minutes and was taken out and shaken for later use. Wheat grain medium. The wheat grains are soaked in warm water for 2 hours, removed and placed in a bamboo sieve, and the water is poured and poured every 4 hours. After about 24 hours, when the grains germinate 0.50 cm long buds, into the pot and boiled (boiled for half an hour) to remove and drain, evenly mix 1% gypsum powder, and then into the test tube, install Into the 1/3--1/2 of the test tube, plug the tampon, sterilize for 15 minutes under 15 pounds of pressure, and take it out. Rice rice medium. Remove the rice and wash it, add 1% sugar, and boil rice as usual. Use rice grains with high hardness, evenly mix 1% rice bran or dried horse manure, pound the rice into pellets, and then put it into a test tube. The loading amount is 1/3--1/2 of the test tube, and the cotton is stuffed. Sterilize at 15 pounds for 45 minutes. Corn grain medium. The corn kernels are crushed (or chopped) into mung bean size, soaked in water, drained, and drained. Stir in 1% calcium carbonate powder and spread into a test tube. Load 1/3--1 of the test tube. /2, plug the tampon, sterilize under 15 pounds of pressure for 45 minutes, remove it and shake it for use. If there is no autoclave, it can be steamed for 2 hours in a household autoclave or sterilized in an ordinary pan for 6 hours. The effect is also very good. The above several mediums are suitable for the culture medium of mushroom, mushroom, and parent mushroom.
