Slide mushroom, also known as slider mushroom, is delicious, nutritious, and enjoys high reputation in the international market. In recent years, the mushroom industry in our county has developed rapidly, but mold contamination has generally occurred. Therefore, whether it can effectively prevent mold contamination is the key to improving the quality and yield of oyster mushrooms. 1, mold species and damage Slide mushroom cultivation, common contaminating molds are Trichoderma, Penicillium, Neurospora and Aspergillus. Such molds rapidly propagate and spread under conditions of high temperature, high humidity, and poor ventilation, and later form green, blue-green, orange-red, yellow, or black molds on the surface of the culture material. At this time, molds competed with the mushroom mycelium for nutrition, and some secreted toxins, affecting the growth and development of oyster mushrooms, of which the most serious damage to Trichoderma. 2, pollution 2.1 Culture material contamination. Inadequate culture formulation, excessive humidity, and incomplete sterilization. 2.2 inoculation pollution. Bacterial discomfort, impure bacteria, poor viability, unsanitary inoculation environment, improper inoculation methods, and common mold contamination around inoculated blocks. When the inoculum size is less than 5% -10%, the growth advantage of the oyster mushroom is not obvious, and the mold will infect. 2.3 Pore hole contamination. The plastic bag is brittle, microporous or mechanically damaged, and the bacteria enter the gap, quickly forming an obvious pollution center. 2.4 Cultivate pollution. This condition is often manifested in the poor air permeability of the pouch fungus and the high temperature and humidity environment suitable for mold reproduction. 3, comprehensive prevention measures To ensure the normal growth and development of oyster mushrooms, to achieve the purpose of high-quality and high-yield, prevention-oriented, comprehensive prevention and control approach should be adopted. 3.1 The correct selection and treatment of culture materials. Before mixing, the raw materials should be exposed to the sun for 3-4 days in order to reduce the amount of bacteria in the feed. The mixture was sterilized with 0.2% of 40% carbendazim, and 0.1% thiophanate-methyl, 0.1% clotrimazole was also used. 3.2 Strictly control the vaccination. High quality and suitable strains are the basis for successful cultivation. When the seedlings are selected, their bacterial age is 25-35 days, the mycelium is thick and white, there is no water accumulation or detachment phenomenon, no primordium of fruit bodies is formed, and no pollution is appropriate. With suitable raw materials and quality strains, the cleanliness of inoculation sites, tools, and inoculation personnel must also be maintained to prevent transmission of infections. 3.3 Protect the cultivation bag. The quality of plastic bags for cultivation is better, and the thickness should be even. Avoid the use of sturdy items. The surface of the bag to be contacted should be smooth and gently handled. The utensils to be transported should be smooth or padded. Both tools and hands need to be disinfected when moving. 3.4 Correctly cultivate management. The inoculated bag was placed at 15-25°C for germination. At a temperature of about 20-25 °C, the air relative humidity of 85-95%, mushroom mushroom mycelium grows rapidly, bacteria are not easy to occur. If the temperature reaches 28-32°C, the relative humidity of air is more than 95%, and the pH is 3.5-6.0, it will cause the growth advantage of various fungi such as Trichoderma and Penicillium. If it is found that there is more water in the bottom of the bag, it can be drained in time and the position of the bag is changed. Otherwise, the mold will be quickly contaminated. In addition, ventilate frequently during mycelium culture to maintain normal temperature and humidity to ensure normal mycelial growth. 3.5 Scientific medication. Frequently inspect bacterial bags, mold contamination should be treated in time to avoid spread. When the fungal spot occurs, 1% Kemodulin is injected into the affected area. If the pollution is heavy, it will be partially flaky. You can first remove the mold and spray 5% lime water on the affected area. Serious pollution must be promptly cleared and buried.
Goji Berry ( [Goji" means [happy") , also called wolfberry, has been used for thousands of years by herbalists in China to protect the liver, help eyesight, boost immune function, improve circulation, and promote longevity and overall well being. It has only recently gained popularity in the west, it has become so polar, in fact, the Time Magazine recently named the Goji berry as [super-fruit" of the year. A big reason why Goji berries have quickly become a favorite nutritional supplement is that its impressive list of ingredients. The Goji berry, also called the wolfberry, is a bright purplish red or purple red berry that comes from a shrub that is native to China. In Asia, goji berries have been eaten for generation in the hope of living longer.
