Abstract We developed a system that waters biocrust moss with fog on a burlap substrate, tested its production capacity, and evaluated field establishment of the moss-colonized fabrics it produced. First, we studied effects of application rate, watering period, and pulverization on biomass increase of Syntrichia ruralis, a globally distributed moss. We observed increases at both high and low application rates, though pulverization impeded growth. In a subsequent experiment studying growth more frequently we observed this species increase by 1.5% in the first 30 days and 17% over 81 days. This confirmed our expectation of a non-linear relationship between time and yield when cultivating tissues that have incurred stress prior to cultivation from the field or during storage. In both experiments moss was loosely attached to burlap following cultivation. We field tested moss-colonized burlap produced in a multi-level fog system, installing it face-up or down, and compared cover change with the same material detached from burlap and with wild moss. We observed losses in all treatments after five months, perhaps due to inactivity and consequent displacement by wind during an anomalous summer drought. However, face-down treatments retained the most cover and regenerated to 60% (initial levels) by the following spring. These levels were four-fold higher than fog chamber materials without burlap association. Fog materials with no burlap association established 8% more cover than wild moss, suggesting that fog materials are as field-ready as wild materials. Thus, moss-colonized burlap is effective at rapidly establishing biocrust in the field, even during drought.

在雾室中生产长满苔藓的粗麻布以修复生物地壳

摘要 我们开发了一种在粗麻布基材上用雾浇灌生物结皮苔藓的系统,测试了其生产能力,并评估了其生产的苔藓定植织物的田间建立。首先,我们研究了施肥量、浇水期和粉碎对全球分布的苔​​藓 Syntrichia villageis 生物量增加的影响。我们观察到在高和低施用率下都有增长,尽管粉碎阻碍了增长。在随后更频繁地研究生长的实验中,我们观察到该物种在前 30 天内增加了 1.5%,在 81 天内增加了 17%。这证实了我们在培养在田间栽培前或储存期间遭受压力的组织时,时间和产量之间存在非线性关系的预期。在这两个实验中,苔藓在栽培后松散地附着在粗麻布上。我们现场测试了在多级雾系统中生产的苔藓殖民粗麻布,将其正面朝上或朝下安装,并比较了从粗麻布上分离的相同材料和野生苔藓的覆盖变化。我们观察到五个月后所有处理的损失,这可能是由于在异常夏季干旱期间不活动和随之而来的风位移。然而,面朝下的处理保留了最多的覆盖率,并在第二年春天恢复到 60%(初始水平)。这些水平比没有粗麻布的雾室材料高四倍。没有粗麻布的雾材料比野生苔藓覆盖率高 8%,这表明雾材料与野生材料一样可用于野外。因此,
