Autumn and winter are the golden season for the production of edible fungi, but the annual economic loss caused by inoculation to mushroom farmers is about 20%. The following five methods can be used to reduce the inoculation contamination rate.
First, the bottled fermented material is loaded with 1 to 2 cm deep fermentation material 4 cm above the bottle from the top of the culture medium, and then sterilized. The advantage is that the bacteria are not easily impregnated with the culture medium, and the strains have the same age.
Second, the wheat germination method allows germination and then bottle sterilization. That is, one-time use of the germs to germinate the germ, the length of the bud is 1 to 2 times the grain, and then fully dried and stored. One day before the bacteria was cultured, the wheat was soaked for 12 hours and directly bottled and sterilized. The advantage is that the process of cooking the wheat grains is eliminated, the bacteria generation is fast, and the bacteria are less. The pollution rate is between 2% and 3%.
Third, the use of liquid culture The traditional culture of bacteria used is a solid medium, solid culture medium has the disadvantage of slow bacterial growth, inconsistent age of bacteria, the chance of contamination with bacteria. The improved method is the use of a liquid medium, which overcomes the disadvantages of the solid medium, and can be directly cultivated using the liquid culture medium as a cultivar, and the contamination rate can be reduced to 2%.
Fourth, from the original species of the bottom of the bottle in the bottom of the bacteria species of the species of bacteria in the bottom of the bacteria, vitality, and less bacteria, hyphae eat faster after inoculation, the pollution rate is low. It is recommended that 1/5 of the original species in the upper part of the bottle be discarded, and the contamination rate can be reduced to 3%.
V. Reasonably arrange the season of seed production. In the high temperature and humidity environment, the growth of the bacteria is fast. The improvement method is to inoculate at a lower temperature, such as morning or evening. If inoculated in an air-conditioned room, the effect is better.
Chinese traditional chicken growth cycle is long, mature slowly, less meat. Meat features more fat, rich flavor, more suitable for soup, braised, white cut and other traditional diet. The introduction of white feather broiler with advanced scientific large-scale collective breeding experience, so that its growth cycle is greatly shortened, and there are more mature and fast meat characteristics, compared with the meat of its own flesh less fat, rich gravy, Fine fibers, the nutrients contained in the body more easily absorbed. Because of the characteristics of white chicken meat, so they are more suitable for deep-fried, barbecue, fried chicken and other cooking methods.
Fresh lamb, high
nutritional value, where lack of kidney yang, Yaoxisuanruan, abdomen
cold pain, labor-deficit who can use it for therapeutic products. Mutton
is rich in nutrition, and is of great benefit to tuberculosis,
bronchitis, asthma, anemia, deficiency of both qi and blood in the
postpartum, cold pain in the abdomen, chills, malnutrition, weakness of
the waist and knees, impotence and premature ejaculation, Bushen impotence, moderate temperature effect of tonic, men are suitable for regular consumption.
