利用腐植土改良覆土性質對洋菇增產效果比較試驗

Experiments on the Effect of Peat-moss Mixed in the Casing Soil for Mushroom Production

1.覆土混拌15%彰化產腐植土可提高洋菇產量98.6%，其增產效果最佳，其次為拌埔裏產泥炭土15%，可提高產量79.8%。2.覆土攪拌15%彰化產腐植土較之混合60%及45%同樣腐植土對於洋菇增產效果差異顯著，較之混合30%，75%及不混合同樣腐植土者其效果差異極顯著。

1. A total of 98.6 percent of mushroom yield was increased by casing of soil mixed with 15% of Chung-hwa peat moss by volume; while substituted 15% of Puli peat for Chung-hwa peat moss, the product was increased only 79.8 percent. 2. The difference of mushroom yied between the amounts of 15% and 45% or 60% of peat moss to ha mixed with soil was significant; and between 15% and 30%, 75% or the check (none peat moss added) was highly significant.
