Mushroom is an edible fungus. It is not a plant and does not need photosynthesis to rent. The nutrients required for its growth are all obtained from its nutrient soil. If the nutrients in the nutrient soil are not enough, it is easy to cause the mushrooms to be small. The top dressing of the mushrooms, then how to top dress the mushrooms? 1. Spray carrot juice: take 10 kg of carrots and chop, add 15 kg of water and boil for 15 minutes, filter and extract juice, add 40 times of water and spray the bacteria bed from 300 square meters to 400 square meters, which can increase the yield of mushrooms by 10%-15%. 2. Mushroom soup: Wash the mushrooms at the harvesting, processing and cutting of the mushroom feet and crushed mushrooms, cut into thin slices, add 1.5 kg of water per kg of material, boil for 15 minutes, dilute the filter juice with water to 10 kg. 30 square meters of mushroom bed. When used at the peak of mushroom emergence, it can make the fruit body thicken and prolong the peak period of mushroom emergence. 3. Apply cow dung and urine: Take fresh cow dung and urine, boil until the foam disappears, add 7 to 8 times of diluted water, dilute it every 2 to 3 days, and spray the bed surface preferably. If there are small mushrooms on the bed surface, spray again with clean water after spraying to promote the growth of small mushrooms. 4. Spray fertilizer solution: Use 0.1%~0.2% urea solution, spray every 2~3 days, it is better to spray wet bed surface. It has the effect of increasing fat and thickening the fruiting bodies of mushrooms in the middle and late stages. It can also be dissolved by using 0.5 kg of superphosphate and 15 kg of water to dissolve the filter juice, and then spraying 50 grams of ammonium carbonate on the bed surface to make the mushroom thick. Increase production by 15% to 200%. 5. Spray salt water: use 0.5 kg of salt and add 50 kg of water, spraying at the peak of mushroom emergence to make the body white. 6. Spraying plant ash: Use plant ash 25 kg, add water 50 kg to soak, spray after filtering to prevent mushroom redness. 7. Spraying soybean milk juice: take 2 kg of soybeans, add water to soften the pulp and grind it into a slurry, filter out the residue and add 80 kg of water, spray the mushroom bed from 80 square meters to 100 square meters, which can promote the growth of small mushrooms and white.

It provides a way to make more copies of a portion of DNA.
We need to have PCR ingredients that include DNA portion, Buffer solution, Primer+DNA (tap polymerase), and Nucleotides during the preparation step.
In the step of PCR sequence, there are three steps in this section.
Step 1 Denaturation
The addition of heat is needed to separate the two strands of the DNA molecule.
Step 2 Annealing
Temperature, is going to be cool in this step, should allow the primers to bind to the specific segments.
Step 3 DNA Synthesis
To make more copies of the DNA.
Those three steps above keep repeating to make enough copies of the DNA fragments. It is the principle of how PCR machine works.
