我们开发了一个系统，沃茨生物锈苔藓与雾在粗麻布衬底，测试其生产能力，并评估其生产的苔藓定殖织物的现场建立。首先，我们研究了施用量，浇水时间和粉碎对全球分布的藓类植物Syntrichia ruralis生物量增加的影响。我们观察到增加在高和低的应用率，虽然粉碎阻碍增长。在随后的一项更频繁地研究生长的实验中，我们观察到该物种在前30天增加了1.5%，在81天增加了17%。这证实了我们对时间和产量之间的非线性关系的预期，即当培养在从田间培养之前或在储存期间受到应力的组织时。在这两个实验中，培养后苔藓松散地附着在粗麻布上。我们实地测试了苔藓殖民麻布生产的多级雾系统，安装它面朝上或面朝下，并比较了覆盖变化与相同的材料从麻布和野生苔藓。五个月后，我们观察到所有治疗的损失，可能是由于不活动和随之而来的位移风在异常的夏季干旱。然而，面朝下的处理保留了最多的覆盖，并在第二年春天再生到60%（初始水平）。这些水平比不含粗麻布的雾室材料高出四倍。雾材料，没有粗麻布协会建立了8%以上的覆盖比野生苔藓，这表明雾材料是野外准备的野生材料。因此，即使在干旱期间，苔藓定殖的粗麻布也能有效地在田间快速建立生物结壳。
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.
