Effect of highly activated calcium for mushroom growth step
p.120
Highly Activated Calcium(below HAC) is the oxidized calcium made by dissolving shell materials with high voltage, about 15,000V, and high temperature(1,500~5,000). This HAC is a material with a very high degree of purity without toxicant. This HAC decreases chemical reaction so the degree of being active and dissolving living material is outstanding. The effects of HAC on the propagation of mushrooms are following. In the case of the Pleurotus ostreatus, when controlling media moisture by mixing with the HAC, mycelium cultivating days were shortened by 2days. The day required for primordial formation after inoculation(DPI) were one day faster, The number of stem was 15 and individual weight was 248g/850cc, a 6.5% increase. In the case of Pleurotus eryngii, when controlling media moisture by mixing with the highly activated calcium, mycelium cultivating days were shortened by 3days. DPI were 1 day faster, The day required for colonization after inoculation was shortened by 6days and individual weight was 108.8g/850cc, a 9.7% increase. In the case of Flammulina velutipes, the highly activated calcium was the best for scraping up mycelium. Mycelium incubating days were shortened by 2days. DPI were shortened by 3days. The day required for colonization after inoculation was 1day faster and the period of cultivation was shortened by 3days. Individual weight was 165g/850cc, a 6.7% increase. In the case of Lentinus edodes, when mixing medial with the highly cultivated calcium, cultivating days were shortened by 3days. The days for becoming brown in color were 2 days faster and the days of the first harvest were shortened by 4days. The weight of mushrooms was 169g/2kg, a 9.7% increase.
