A Detailed Guide to the Methods of Capturing and Taming Wild Hazel Grouse
The history of artificial breeding of wild hazel grouse is still less than 10 years, so capturing and taming are effective ways to solve the shortage of breeding stock. 1. The trapping time is best from September to November each year. They lay eggs in May and the chicks hatch in June; during this period the hazel grouse is in plump body condition, reaching its highest weight of the year. 2. Trapping methods: set up some homemade trapping tools in areas where hazel grouse are frequently active, such as snares, capture cages, etc. If conditions permit, you can make full use of the hazel grouse's flocking tendency by continuously imitating the hazel grouse's call to make the birds gather together, and then capture them with a net. 3

Comprehensive Control Methods for Damping-Off Disease in Spruce Seedlings Grown in Greenhouse Tunnels
In high-cold mountain areas, greenhouse tunnel seedling cultivation is usually adopted to shorten the cultivation period of spruce seedlings and enable earlier out-planting. The special environment of the greenhouse tunnel creates conditions for the breeding and spread of various pathogenic bacteria and organisms that cause damping-off in newly sown spruce seedlings, and improper control can lead to failure of seedling cultivation. To control damping-off in newly sown spruce seedlings in greenhouse tunnels, the policy of "prevention first, comprehensive control" must be adhered to. 1 Damping-off symptoms The symptoms of damping-off mainly manifest in 4 types: (1) After sowing but before emergence, seeds and ungerminated sprouts rot and die in the soil,

Many Methods for Propagating Goji Berry: A Full Analysis of Commonly Used Propagation Techniques
1. Seed propagation: Spring sowing should be carried out from late March to mid-May, when temperatures rise noticeably. Soak the seeds in 30°C warm water for 24 hours, then rub them, pick out the flesh and skin, take out the sunken seeds, and dry them. Mix the seeds with wet sand at 1:3, then place them indoors at about 20°C to germinate, keeping them moist. When about 30% of the seeds have cracked and shown white, germination is complete. For the nursery site, loam or sandy loam near a water source can be chosen as the seedbed. It requires flat terrain, good drainage, and ample sunlight. Apply 5000 kg of decomposed barnyard manure per mu
