Ganoderma lucidum cultivation techniques
I. Cultivation techniques 1, the production of cultivars. The raw material formula is 60% cottonseed hull, 20% wood, bran 20%, sugar 1%, bean cake 2%, gypsum, lime 1.5%, magnesium sulfate 0.4%. During the preparation, the main ingredients are mixed and mixed dryly, then sugar, lime, and magnesium sulfate are dissolved in water, sprayed in the main ingredient, and then mixed and mixed until the water content is even (60-65%). It is best to use 1735CM of propylene material in the strain bag, with two ends tied and two inoculated. Each bag can hold 0.5 kg dry material. When loading, it should be tight and tight, and the two bags should be fastened tightly. After the bags are packed, normal pressure (or high pressure) sterilization is performed in a timely manner. When the temperature reaches 100° C., it is maintained for 8-9 hours. After the ceasefire, it is boring for 5-6 hours before the pans are allowed to dry. When the temperature of the bag falls below 30°C, it can be inoculated. Inoculation must be strictly controlled, aseptic operation, reduce pollution. During the germination phase, the light is dark, the air humidity is controlled below 70%, and the temperature is maintained at 24-28°C. Bags were returned once every 7-10 days, and it was found that the contamination was removed in time. Generally, after 25-30 days, the hyphae can be filled with a bag, and after 5-7 days, it can be expanded. The mycelium culture is the same as that of the cultivar when it is expanded. 2, out of the management of Chi. Chiba can be arranged from late April to mid-October. When the mycelium of Ganoderma lucidum is filled with mycelium and the original primordium begins to appear, it can be administered. Because of its short handle or even no handle, the purple zizhi can not be fully bagged when covering the soil. It should leave a 2-3 CM bag in one head, and the rest should be removed completely and then cover the soil. The soil should be covered to 0.5cm below the bag mouth to prevent the soil layering of the stalks and affect the quality. About 50 bags per square meter, the spacing between the bags is about 2CM. After the soil is covered with a watering can, the remaining soil of the bag head is washed away, and the bags are cut off in two days. Zhifu should not be too wide, 80CM is appropriate, after finishing the soil, began to control the temperature. Grasp 22-30 °C, the air temperature is controlled at 85-90%, increase light, ventilation so that buds formed early, rapid differentiation. Under suitable conditions, it usually takes about 40 days from cultivation to picking. The sign of maturity of Ganoderma lucidum is that the cap of the fungus grows thin and thick, and its color changes from light yellow to reddish brown. The white growth circle around the cap has disappeared, and a small amount of spore powder is scattered in the tube. The cap becomes light color. The mature Ganoderma lucidum has stopped growing, and its ability to resist counter-resistance to bacteria has weakened. In addition, the temperature and humidity of the Ganoderma lucidum shed is high, so it is susceptible to miscellaneous bacteria. Therefore, it is necessary to harvest in time, harvesting knife can be cut from the root of the Zhizhi handle or hand-twisted Zhizhi directly, the Ganoderma lucidum should be placed on a clean cement field in time to dry, to prevent debris from adhering, It can be dried at 40-60°C to reduce the moisture to 12%.
Broccoli powder is a good anti-cancer ingredient. The rich vitamin C content in broccoli can help the body improve immunity and has anti-cancer effects. Broccoli contains a lot of cellulose, cellulose has a very good effect on the human stomach and intestines, and can reduce the cholesterol content of the human body.
