After cooling, it should be dissolved to 1000ml with heavy distilled water, and then heated to make a stable transparent solution(3 inch square pots). 5ml of each mixed IL medium can be taken. All the tools used for inoculation should be disinfected on the flame of alcohol lamp, and then disinfected. Finally, wipe and disinfect the super clean table with new jieermin and 70% alcohol(plastic garden pots wholesale). The prepared solution must be put into the refrigerator to prevent deterioration.

Trace elements can be prepared 100 times of mother liquor, dissolved to 100 ml, adding 1 ml for each 1 l medium.
(bulk buy cheap plastic clone trays australia)Then, the all-optical spray can also reduce the great changes in the ambient temperature around the cuttings(4 gallon planter), reduce the respiration of the cuttings, and the nutrients added to the cuttings are more than those used for breathing. After selecting suitable culture medium according to different perennial plant species, it is necessary to prepare mother liquor with large amount of elements, trace elements and organic matter(large plastic planters cheap), and enlarge multiple as diluent for storage.
Sucrose: the concentration of sucrose is generally 3%, the concentration of agar is about 0.7%, the pH of medium is 5.4-6.2, and the commonly used pH is 5.8(five gallon pot). Organic nutrients must be prepared separately. Generally, 50 times of the dosage can be weighed. After being dissolved in distilled water, the volume can be adjusted to 50ml. 1ml of each mixed IL medium can be taken(72 cell trays bulk). 100 ml mother liquor can be taken for every 1 l medium.(bulk buy cheap plastic clone trays australia)
Auxin: generally, 50mg can be weighed and put into a small beaker(white plastic hanging baskets), dissolved with a few drops of 95% alcohol, and then diluted to 50ml with hot distilled water (about 80 ℃), and then put into a brown bottle to avoid oxidation into pink.
