Key techniques of early Operation of Edible Fungi Culture material
It is very important to make a good culture material of edible fungus, which directly affects the growth of edible fungus and the benefit of growers. Here I will take Gymboree starter as an example to introduce the essentials of operation.
1. Preparation: according to 0.1% of the weight of the culture material (that is, 1/1000, if the newspaper waste is reused, 0.2% can be added) to prepare Gymboree edible mushroom culture material fermentation auxiliaries; pre-soak or pre-wet the crushed or cut-off main materials, adjust the moisture to 60%, 70%, and the PH value is about 8. If the moisture is too low, it is not conducive to the rapid reproduction of functional microorganisms, and the fermentation speed is slow; if the moisture is too high, not only the temperature is slow, but also the local anaerobic environment may be caused by poor ventilation, resulting in the bad smell caused by the reproduction of "spoilage bacteria". The way to judge whether the moisture is appropriate or not: hold on to a handful of material with your hand and see the watermark without dripping.
2. mixing: using fresh rice bran (note: "rice bran" is not "uniform bran". The nutrition and air permeability of rice bran are good, while the nutrition of old rice bran or rice bran is poor. If there is no rice bran, you can use wheat bran or cornmeal instead of wheat bran. Dilute the Gymboree fermentation auxiliaries with wheat bran, cake fertilizer, manure and other auxiliary materials, and then evenly mix them into the main material.
3. Pile-making: mix the culture materials evenly and stack them according to the routine. The stacks are evenly perforated and ventilated with pointed rods about 10 cm in diameter, and covered with sacks, straw curtains and other breathable coverings for heat preservation and moisturizing.

Preparation of Mother Culture medium for Edible Fungi
1. 800 grams of corn, 20 grams of glucose, 20 grams of Agar, 1.5 liters of rice water. First, boil the corn kernels in dilute Amoy rice water, pick them up when a small amount of corn kernels burst and filter. Continue to heat the filtrate (if the filtrate is less than 1 liter, add clean water to make up), add Agar and glucose, stir until all the Agar dissolves, then separate the test tube, sterilize and place the bevel. two。 Fresh Pleurotus ostreatus or mushroom foot 200 grams, glucose 20 grams, Agar 20 grams, water 1 liter. The preparation method is the same as potato glucose Agar medium. 3. Wheat bran 2

Smart picking of edible fungi
Edible fungi are vegetables rich in nutrients and popular with urban and rural people. They are also an important way for farmers to increase their income. Therefore, in the process of picking, we should master the following techniques: First, master the best harvest period. All kinds of mushroom ears basically have beautiful appearance, fresh complexion and delicious taste when they mature in July and August. Take shiitake mushroom as an example, the mature sign in July and August; the bacterial membrane has been broken, the cap has not been fully developed, there are still a few inward rolls, forming a "gong edge", the pleats have all elongated, from white to white
