如何收集羊肚菌的样本进行分析?

Materials:

• Fresh sheep's dung
• Container for collecting dung
• Knife or scalpel
• Container for holding the sample
• Labels for each sample

Procedure:

1. Collect fresh sheep's dung:

   • Find a clean and undisturbed area where sheep have recently defecated.
   • Use a knife or scalpel to dig a small hole in the dung and extract a small sample (about 10-15 ml).
   • Make sure to collect a sample that is representative of the dung and free from any debris.

2. Label the sample:

   • Label each sample with its unique identifier, such as its location or date of collection.

3. Store the sample properly:

   • Transfer the sample to a container for holding the sample.
   • Use a clean container to avoid contamination.
   • Store the sample at room temperature in a sealed container.

Additional tips:

• To ensure the sample is fresh, collect it just before examining it.
• Avoid collecting samples from animals that are sick or injured.
• Handle the sample with care to prevent contamination.
• If the dung is wet or difficult to handle, you can dry it with a clean cloth before collecting the sample.
• Store the sample in a cool, dry place.
