不同栽培基质对香菇头潮菇产量及子实体营养成分的影响

为了缓解香菇传统栽培过程中的木屑资源短缺问题,充分利用果木废弃物,试验选择香菇‘K5’作为试验材料,以杂木、桑木、苹果木和枣木为栽培基质,每种基质设3个氮含量处理水平,通过测定并分析不同基质头潮菇产量及子实体的有机质、氮、磷、钾含量,研究不同栽培基质对香菇头潮菇产量及子实体养分的影响。试验结果表明:4种果木屑均可作为香菇的栽培基质,其中枣木C配方和桑木A配方生产的香菇头潮菇产量和生物学效率较高,但是以桑木做栽培基质生产的香菇,头潮菇结束后菌棒便开始萎缩,不利于后期出菇。枣木C配方生产的香菇,其有机质、氮、磷、钾等营养成分均处于较高水平,因此,在香菇代料栽培中可以使用枣木代替传统的阔叶树木屑。

Influence of Cultivation Medium on Yield and Nutrient Composition of the First Tide Mushroom

This experiment select mushroom K5 as experimental material and sets four kinds of cultivation medium including hardwood,mulberry trees,apple trees and jujube trees,and each medium set three treatment levels of nitrogen content.We attempt to study the influence of different cultivation medium to the yield and nutrient composition of the first tide mushroom through testing and analyzing the yield and the content of organic matter,nitrogen,phosphorus and potassium.The result indicates that four kinds of fruit trees can be used as the cultivation medium of mushroom, and the production and the biological efficiency of the jujube C and mulberry A are higher than others.But when the mulberry trees as the cultivation medium,the mushroom-stick began to shrink after the first tide,and it is not conducive to the late fruiting.The nutritional including the organic matter,nitrogen,phosphorus,potassium of the jujube C are at a higher level,therefore,jujube trees can be used instead of the traditional hardwood as the cultivation medium in the mushroom substitute cultivation.
