Q: Is it difficult to cultivate Chlorella? Can the production team cultivate Chlorella?
A: The culture technology of Chlorella is not complicated, as long as we master the key technology of Chlorella production and strengthen management. The equipment for cultivating Chlorella is also very simple. For example, the grain drying field with cement bottom is surrounded by a wall two or three feet high when not drying grain, which is a good production pool; Idle cesspits can also be used; It would be better if a new production pool could be built. In addition, a stirrer (which can be replaced by a grain rake), a dustpan and water are needed.
Barrels, as well as human and animal manure, a small amount of fertilizer powder, etc. These things can be done by the production team.
The following technical keys should be paid attention to in Chlorella production: ① The culture medium should be rich in nitrogen, phosphorus, potassium fertilizer and trace nutrients such as iron, magnesium, manganese and sodium. ② The temperature should be suitable, preferably 24 to 28 degrees Celsius. (3) Sufficient sunshine, at least four hours a day, preferably more than eight hours. (4) Stir four or five times a day to increase air and carbon dioxide. (5) The culture medium is preferably neutral, for example
If the acidity is too high, caustic soda can be added; If the alkalinity is too high, add sulfuric acid or dilute hydrochloric acid.
Q: Is there any simple way to determine the pH value of the culture solution?
A: Generally, the culture solution made of 4% ~ 8% decomposed human feces is mostly neutral, and it is not necessary to determine the pH value. If it is necessary to determine the pH value, you can soak the universal pH test paper (available in western pharmacies) in the culture solution. After five or six seconds, compare the color of the test paper with the standard color. Blue is alkaline and red is acidic.
Q: How to prepare human feces culture solution?
Answer: The decomposed human excrement is filtered by double-layer sacks, and four to eight kilograms of human excrement are added into 100 kilograms of water to form a human excrement culture solution. Using 5% chicken manure as culture medium, the effect of cultivating Chlorella is also very good. Feces from cattle, pigs, sheep and rabbits can also be used as culture media.
Q: How to cultivate algae seeds?
Answer: First, prepare the culture solution and inoculate the algae seeds into the culture solution. Pay attention to temperature, sunshine and stirring. After Chlorella grows and reproduces, a small amount of culture solution is added every one or two weeks to supplement nutrition.
Q: What should I do if I find animal carcasses and paramecium in the production pool?
A: Chlorella can't grow when paramecium and calla lily are found in the pond. Dropping a small amount of iodine solution can kill paramecium; Add 6% wettable BHC (2.5g per100kg Chlorella solution) to kill cicadas.
Q: How much Chlorella is used to feed pigs?
Answer: Boil the concentrated Chlorella solution and feed it to pigs with green roughage. The dosage should not be too much, because it is not easy to digest if you eat too much. Generally, pigs weighing 50 kg or 60 kg eat 3 kg of concentrated Chlorella every day; If you weigh 60 to 100 kg, you can eat four to five kg of concentrated Chlorella.
Q: The temperature is too high in summer and too low in winter. Can Chlorella be cultured?
A: Facts have proved that Chlorella can still be produced outdoors in summer and winter as long as it is cooled and kept warm. Bamboo curtains can be used at noon in summer to prevent direct sunlight from reaching the pool water. The temperature is too low in winter,
