为了研究不同栽培基质香菇氮、磷、钾运转规律,筛选适合香菇生产的栽培基质,本试验选择香菇‘K5’为试验材料,以杂木、桑木、苹果木和枣木为栽培基质,研究了不同栽培基质下香菇菌棒中氮、磷、钾的含量变化及其养分利用率。结果表明:香菇菌棒中的氮、磷、钾含量均呈现先升高后降低的趋势,且在转色完成时达到最高值;枣木基质和苹果木基质栽培的香菇,其菌棒中的氮、磷、钾含量以及养分利用率均处于相对较高的水平,因此,在香菇代料栽培中可以考虑使用枣木屑和苹果木屑代替传统的阔叶树木屑。
Abstract
To study the translocation rule of nitrogen, phosphorus and potassium in different cultivation mediums and select the optimal cultivation medium for mushroom production,‘K5’was used as the material, and cultivation mediums were hardwood, mulberry trees, apple trees and jujube trees. The content change of nitrogen, phosphorus and potassium and the nutrient utilization of mushroom sticks in different cultivation mediums were detected. The results showed that the contents of nitrogen, phosphorus and potassium in mushroom stick first increased and then decreased, and reached the highest when the color transform was completed. The contents of nitrogen, phosphorus and potassium of mushroom stick and their nutrient utilization rated were at a relatively high level in the jujube trees and apple trees. Therefore, from the nutrient utilization of mushroom stick, jujube trees and apple trees could be used as the cultivation medium instead of the traditional hardwood.
