不同原料栽培平菇的生态学转化特点研究

Ecological features of matter conversion or mushroom(Pleurotus ostreatus) cultured on different media

运用熟料袋栽方法对小麦杆和棉籽壳栽培平菇的转化特点进行了研究．结果表明平菇生产转化率（Ｒｃ）无显著差异，剩余率（Ｒｒ）和耗出率（Ｒｄ）有极显著差异，Ｒｃ、Ｒｒ和Ｒｄ相互间有极显著的直线回归关系．不同处理中Ｒｄ对Ｒｃ的回归系数（ｂ）一致，但回归截距（ａ）有较大差异，Ｒｄ对Ｒｒ的回归系数（ｂ）和截距（ａ）都有显著差异，但ｂ与ａ之比却十分接近．说明平菇生产中对原料的消耗可分为两个部分，一是基础消耗，与平菇产量无关，二是生产直接消耗，与平菇的产出率呈正相关．

The ecological features of matter conversion of mushroom cultured on sterilized and bagged wheat straw and cotton seed shells are studied in the paper. No significant difference of conversion rate (Rc) was found. but significant difference was existed in residue rate (Rr) and dissipation rate (Rd) when mushroom was grown on different media. Highly significant linear regressions were found between Rc, Rd and Rr. In different treatments, the regression coefficients (b) of Rd against Re are consistent, but the regression intercepts (a) have larger variation I both b and a of Rd against Rr show a significant variation with very closed ratios of b/a. The results indicat that the dissipation of original materials for mushroom cultivation could be devided into two parts: the basic dissipation irrelative with mushroom yield and the direct production dissipation positivily correlated with output rate of mushroom production.
