“以草替代木材”项目可以部分解决蘑菇生产和平衡生态系统之间的冲突,促进农业经济可持续性。肺叶侧耳是一种经济上重要的食用和药用蘑菇,传统上使用由木屑和棉籽壳组成的基质生产,补充麦麸。采用单纯形晶格设计,以农残为主要底物,以替代木屑和棉籽壳,对肺虫的栽培进行了系统优化。不同数量的小麦秸秆的影响,玉米秸秆,和大豆秸秆对产量的影响,菌丝生长速率,刀柄长度,绒头长度,绒头宽度,并证明了收获的时间。结果表明,混合的小麦秸秆,玉米秸秆,大豆秸秆可能对这些变量中的每一个都有显著的积极影响。然后将高产综合配方优化为包括40.4%的小麦秸秆,20.3%玉米秸秆,18.3%大豆秸秆,加上20.0%的麦麸,和1.0%轻质CaCO3(C/N=42.50)。生物效率比对照高15.2%。最令人鼓舞的是,表明高产综合配方可以将达到生殖阶段的时间缩短6天,与对照相比。根据这项研究的结果,农业残留物可用作木屑和棉籽壳的合适替代品,作为肺假单胞菌的主要栽培基质。这些结果为食用菌栽培“以草代木”项目提供了理论依据。
The \"replacing wood by grass\" project can partially resolve the conflict between mushroom production and balancing the ecosystem, while promoting agricultural economic sustainability. Pleurotus pulmonarius is an economically important edible and medicinal mushroom, which is traditionally produced using a substrate consisting of sawdust and cottonseed hulls, supplemented with wheat bran. A simplex lattice design was applied to systemically optimize the cultivation of P. pulmonarius using agro-residues as the main substrate to replace sawdust and cottonseed hulls. The effects of differing amounts of wheat straw, corn straw, and soybean straw on the variables of yield, mycelial growth rate, stipe length, pileus length, pileus width, and time to harvest were demonstrated. Results indicated that a mix of wheat straw, corn straw, and soybean straw may have significantly positive effects on each of these variables. The high yield comprehensive formula was then optimized to include 40.4% wheat straw, 20.3% corn straw, 18.3% soybean straw, combined with 20.0% wheat bran, and 1.0% light CaCO3 (C/N = 42.50). The biological efficiency was 15.2% greater than that of the control. Most encouraging was the indication that the high yield comprehensive formula may shorten the time to reach the reproductive stage by 6 days, compared with the control. Based on the results of this study, agro-residues may be used as a suitable substitution for sawdust and cottonseed hulls as the main cultivation substrates of P. pulmonarius. These results provide a theoretical basis for the \"replacing wood by grass\" project on edible mushroom cultivation.
