The experiments showed that the optimum temperature for fruitbody of Hericium erinaceus was about 25℃ for the strain Hou 3 and about 20℃ for Hou 1 and Hou 2. The biological efficiency of Hou 3 was the highest, followed by Hou 2, and that of Hou 1 was the lowest. However, Hou 2 and Hou 1 showed its higher growth rate, shorter growth duration and higher stress resistance. While the fruitbodies of Hou 3 appeared more compact. All the three strains studied had similar nutrition composition. A C: N ratio of 17—26:...

However, Hou 2 and Hou 1 showed its higher growth rate, shorter growth duration and higher stress resistance. While the fruitbodies of Hou 3 appeared more compact. All the three strains studied had similar nutrition composition. A C: N ratio of 17—26: 1 was desirable for the cultural media of all the three strains. Higher ratios (30:1) tended to suppress their biological efficiency. Hou 3 showed a greater Cu and Pb enrichment capacity than Hou 2 Hou 1, but Cu and Pb concentration in their fruitbodies was too low to affect their food or medicine value. The adoption of sawdust or rice straw in place of cotton seeds was profitable. The formulation of the substrate with distillers grains as a component required further improvement.

The enrichment capability of native zinc by iron oxide, manganese oxide and organie matter in 18 soils of the eastern China were studied with the sequential extraction fractionation procedure. Soils used include 5 acid soils, 5 neutral soils and 8 calcareous soils which are derived from 11 kinds of parent materials from south to north in China.The enrichment capability of native zinc by per unit soil components is different from enrichment capacity of soil components, and a comparative study of them were conducted.The enrichment capability of native zinc by per unit components may be expressed as enrichment distribution ratio (EDR) and enrichment capacity as distribution coefficient (DC):EDR=(enrichment capacity/total zinc/amonnt of component) × 100,DC=(enrichment capaeity/total zinc) × 100,EDR of various components in soils of the eastern China is, in general, as follows: manganese oxide>iron oxide>organic matter and amorphorous iron oxide>crystalline iron oxide, being in the same order as the enrichment capability of per unit of these components. In addition, there is the same tendency for enrichment capability of per unit of these components from acid soils to calcareous soils, i.e., calcareous soils>neutral soils> acid soils. This shows that enrichment capability of per unit of components is related with their properties and increases with soil pH.The distribution of EDR. of soil components is characterized by somewhat geography distribution especially for iron ,oxide. From south to north in the eastern China, the EDR of iron oxide increases. It is≤5 in acid Soils, 5—15 in neutral soils and ≥15 in calcareous soils. Geography distribution is related with the effect of soil pH on the enrichment capability of zmc in soil. The optimium regression equation ,of EDR of iron oxide (y) with.8 soil properties (x) is that: y =-20.80+6.26pH (r=0.64~(**), n=18). Soil pH is one of the most irnportant factors controlling the enrichment capability especialIy for iron oxide.But the enrichement capacity of native zinc by various soil components as DC is in the following order: iron oxide>organic matter>manganese oxide and Cox. iron oxide>Amor. iron oxide. This shows that although the enrichment capability of per unit of manganese oxide is more than.that of iron oxide, the enrichment capacity of iron oxide is more than that of manganese oxide becouse of more iron ,oxide in soil. The same as Amor. iron oxide and Cox. iron oxide. On the other hand, this relates with the transformationof amorphorous iron oxide Zn into crystalline iron oxide Zn with the elapsing of time.The enrichment capacity of iron oxide in different soils is as follows: calcareous soils>neutral soils>acid soils.And it is obvious that the enrichment capacity of soil components depends not only on the enrichment capability of per unit of soil components, but also on the components amount in soil.
