Data underlying the publication “Feeding growing mushrooms”.

Button mushrooms (Agaricus bisporus) are cultivated on a substrate prepared of composted wheat straw, chicken and/or horst manure and gypsum. <br>This manuscript describes a number of experiments indicating that in a harvesting strategy towards quality mushrooms there is a fixed amount <br>of nutrients prepared/available to feed two flushes. The increase of mycelial biomass in the substrate after venting and especially during the <br>development of flush one indicates that likely a branching of mycelium occurs during this period, leading to a substantial number of growing <br>hyphal tips excreting lignocellulolytic enzymes that degrade substrate and make nutrients available during flush one which are utilised in <br>flush one and two. The presently used substrate seems to have reached its limits and there are hardly opportunities for further improvement. <br>Research on alternative, more energy dense, substrates are needed to improve the efficiency of the present production system.

纽扣菇（双孢蘑菇，Agaricus bisporus）以腐熟小麦秸秆、鸡粪和/或厩肥及石膏配制的栽培基质进行栽培。
本文通过多组实验证实，在以产出优质菇为目标的采收策略中，可供两潮菇生长的养分总量固定。
通风后尤其是第一潮菇发育阶段，基质内菌丝生物量显著提升，表明此阶段菌丝大概率发生分枝，由此产生大量活跃的生长菌丝尖端，分泌木质纤维素降解酶分解基质，为第一潮菇提供可利用养分，此类养分同时可被第二潮菇利用。
当前使用的栽培基质似乎已达性能极限，几乎无进一步优化空间。
亟需开展替代型高能量密度基质的相关研究，以提升现有生产系统的整体效率。
