The edible mushroom Volvariella volvacea or straw mushroom is extensively cultivated throughout the year in countries with warm and humid climates. It has the potential for integration into agroforestry food production systems and support food security strategies via climate- and environmental-friendly agriculture, without adversely affecting forest ecosystems. This study aims to ascertain the effect of microclimate on the production of V. volvacea by adapting outdoor cultivation methods to logged lowland dipterocarp forests, along with the application of oil palm wastes as a growing substrate. The study measured a range of microclimatic variables including bed temperature and humidity, as well as bed orientation. Freshly processed planting material from oil palm empty fruit bunches (EFB) was partially composted using conventional open-air composting method and then used as a growing substrate. V. volvacea was cultivated on twenty planting beds composed of EFB, with north–south and east–west orientations, over 4 replication periods, between November 2017 and May 2019, and mushroom production was measured. The analysis found that bed humidity, bed temperature, harvesting week, harvesting month, and replication significantly affected V. volvacea production, while bed pH and orientation did not affect production. Varying temperature and humidity particularly during incubation, for mycelial growth and fruiting body development, as well as harvesting period, are important factors affecting mushroom production. Our study showed that lowland dipterocarp forest provide an ideal setting for cultivating edible mushrooms. Further investigation should be conducted to ascertain the potential for cultivating V. volvacea in other tropical agroforestry contexts, and to assess its potential to mitigate climate change and contribute to a circular economy through recycling oil palm wastes.

可食用蘑菇Volvariella volvacea或草菇在气候温暖潮湿的国家全年广泛种植。它有可能融入农林业粮食生产系统，并通过气候和环境友好型农业支持粮食安全战略，而不会对森林生态系统产生不利影响。本研究旨在确定小气候对草菇生产的影响通过将户外种植方法应用于砍伐的低地龙脑香林，同时将油棕废料用作生长基质。该研究测量了一系列小气候变量，包括床温和湿度，以及床的方向。来自油棕空果串 (EFB) 的新鲜加工的种植材料使用传统的露天堆肥方法进行部分堆肥，然后用作生长基质。2017 年 11 月至 2019 年 5 月，在由 EFB 组成的 20 个种植床中栽培草菇，南北向和东西向，4 个复制期，并测量蘑菇产量。分析发现，床温、床温、采收周、采收月、繁殖对V. 草菇产量，而床层 pH 值和取向不影响产量。温度和湿度的变化，特别是在孵化期间，对于菌丝生长和子实体发育以及收获期，是影响蘑菇生产的重要因素。我们的研究表明，低地龙脑香林为种植食用菌提供了理想的环境。应进行进一步调查，以确定在其他热带农林业环境中种植草菇的潜力，并评估其通过回收油棕废料缓解气候变化和促进循环经济的潜力。
