One, warming and warming 鹌鹎 at a suitable temperature 15-25 °C between the appetite, egg production, egg fertilization rate is also high; below 15 °C egg production rate decreased significantly. Therefore, in the winter or early spring, measures should be taken to increase the temperature of insulation, night in the cage should be covered with insulation items, appropriate increase cage density, can be raised 90-100 per square meter. Or in the leeward sunny place double plastic shed (two-story film interval 5-10 cm) to raise crickets; can also build double sheds, filled with chaff, chaff, sawdust, etc., at night covered straw insulation.
Second, increase the light production of egg tarts each day requires 12-14 hours of light time. In winter, artificial lighting must be added. Each 30-40 square meter is equipped with a 40-watt electric light. Lights are turned on 2 hours before dawn every day. Lights are turned off 2 hours after darkness to maintain stable illumination and time.
Third, balanced nutrition Winter should be fed a comprehensive nutritional feed, and provide the right amount of sand for free access to feed, to help digestion.

Like summer management, daily maintenance of cages and cleanliness of eating and drinking are continued. Every cubic meter of space is fumigated with 25 ml of formalin and 12.5 g of potassium permanganate. Every 7-14 days with 2% -3% of the water in the kitchen utensils inside and outside disinfection once.
Fifth, timely prevention and control of disease winter cages are generally more intensive, once the disease, timely isolation and treatment. Anti-churning white diarrhea can be used for furazolidinone (20 grams per 100 kg of feed plus furazolidone) for 7 days. Treatment of ulcerative colitis, intramuscular injection with penicillin, 10,000 units each time, sooner or later, or gavage sulfamethoxazole, each time a quarter, the first double, twice a day, continuous administration 5 days. For the treatment of bronchitis, 0.005% tylosin was added to the feed for 10 days, stopped for 5 days, and then administered for 5 days. Tylosin and erythromycin were added to drinking water while feeding.
Lycium barbarum is rich in nutrients, but it is also a product that is difficult to preserve. Often due to environmental conditions, the emergence of insects, moldy, discoloration and so on. During storage, attention should be paid to controlling water content, temperature, oxygen content in the air, pest control and pest control. The fruit of Lycium barbarum takes longer time to bake and dry. It needs energy consumption or restricted by natural weather, and the processing cost is increased.
