There are many species of miscellaneous bacteria that are parasitic on Mushrooms. Trichoderma, Schizophyllum, Pleurotus ostreatus, Lepidium notatum are common. In terms of pests, it is harmful to the oysters, snails, horses, etc. of the fresh mushrooms, the larvae of the larvae of the harmful mushrooms, larvae and termites. In prevention and control, we should implement the principle of "prevention first, comprehensive prevention and control," and strengthen the scientific management of mushroom farms in mushroom trees to create an environment conducive to the growth of shiitake mushrooms, which is not conducive to germs and pests. Take precautions before they happen, and extinguish them in time if they occur. Mushroom mushrooms can be scraped off with a knife or coated with 2% lime water. For insects such as snails and slugs, they can be killed manually in the early morning or late afternoon. For the termites, mixed powders of 60% of arsenic acid (arsenic acid, arsenic, cremation), 40% of talc; 46% of arsenic acid, 15% of salicylic acid, and 5% of iron oxide can be applied to the ant and ant nests. On prevention and treatment. Poultry and Pest Control: Common bacteria are Trichoderma, Penicillium, Mucor, Rhizopus, Aspergillus, Streptomyces and so on. The prevention and control of germs should adopt comprehensive prevention and control measures. In addition to the selection of raw materials and strains, and the disinfection of fields and utensils, they should also be adopted in cultivation: The culture materials are first subjected to composting, using the biological heat generated by various high-temperature microorganisms to kill pests and mesophiles and reduce the sources of pollution. Fast bag sterilization. After the preparation of the culture is acidic, suitable for a variety of microbial growth and reproduction, it should be installed within 5 hours as far as possible, when sterilization requires 4-6 hours to raise the temperature to 100 °C. Cooling and ventilation in the cultivation room can reduce the contamination of bacteria and increase the yield of inoculation. If it is necessary to prevent the contamination of Trichoderma, the inoculated bag can be cultured at 16°C first. At this time, the mycelium of the mushroom can grow, and the spores of Trichoderma are difficult to germinate, and the mycelium grows slowly. (The optimum temperature for the growth of Trichoderma mycelia For 25-30 °C), after the mycelium of the mushroom grows to a certain degree on the surface of the culture material, the temperature is gradually increased. Finally, the whole mycelium is grown at 25°C. If cultured at 25°C from the outset, the growth of Trichoderma mycelia is beneficial, and the contamination rate of germs is high. Locally contaminated bacterial bags can be injected with 20% formaldehyde solution or 5% stearic acid to control the spread of contamination points. The prevention and treatment of cockroaches and termites can be carried out in accordance with the control methods for wood cultivation. For the prevention and control of the worms, 0.1 dichlorvos can be immersed in a small amount of honey during the fruiting period, or sprayed with 0.1% rattan extract or 150-200 times pyrethrum liquid.
According to the number of barrels, Piston-typed Mobile Milking Machine can be divided into two categories: Single-barrel Type and Double barrel Type.
With unique design, easy operation, easy maintenance, it can lower the utility costs. It will not hurt the nipple by milking soft with stable vacuum. The milking cup group is with a transparent tube, so the operator can observe the nipples of cows during the milking.
After years of production and constant technological improvements, the new designed milking machines can meet the actual demand for the majority of users. We discuss and improve more about the machine, to make them catch international standards, and suitable for more users in different countries. The portable Milking Machine is not only used for the individual animal in small farm, but also provides a selection for large-scale dairy farms for some special animals.
