什么是无菌的土壤吗？
Sterile soil is either soil purposefully sterilized for growing plants, or soil unable to sustain life.目的地为植物生长，或无法维持生命的土壤消毒灭菌土壤要么土壤。 Sterile soil can either refer to soil purposefully sterilized for special needs of horticulture or agriculture, or to soil that is no longer able to sustain life.无菌土壤，既可以指故意园艺或农业的特殊需要消毒的土壤，或不再能够维持生命的土壤。 Soil that is intentionally sterilized has both benefits and disadvantages for growing plants, while soil that is unproductively sterile requires either natural or human-guided remediation to be able to support plant life once more.土壤，是故意消毒的好处和缺点，为植物生长，而非生产性无菌的土壤，需要自然或人为引导的整治，能够再次支持植物的生命。
Sterile or sterilized soil (used interchangeably) has been chemically or heat-treated to prevent harmful pathogens from harming plants.无菌或灭菌土壤（交替使用）已被化学或热处理，以防止危害植物的有害病原体。 The logic behind this is that these pathogens might be present in the soil, so all microbial organisms are killed off, effectively sterilizing the soil.这背后的逻辑是，这些病原体可能是目前在土壤中，使所有的微生物都死光了，有效地消毒土壤。 Chemicals are used to fumigate the soil, while heat-based sterilization relies on cooking the soil in an oven or microwave, or solarizing the soil by spreading clear plastic over it during the summer and letting direct sunlight blast the soil with heat and ultraviolet rays.化学品的使用熏蒸的土壤，而基于热杀菌的土壤，在烤箱或微波炉烹调，或solarizing在暑假期间传播的透明塑料，让阳光直射下爆炸的热量和紫外线的土壤土壤的依赖。
Seeds and seedlings in particular are susceptible to damping-off, a soil-borne disease that kills the germinating plant before it has the chance to resist.特别是种子和幼苗易患立枯病，土壤传播的疾病，死亡之前，它已经发芽的植物抵抗的机会。 House plants and other potted plants are grown under conditions where many pathogens and pest insects that spread pathogens aren't exposed to natural predators.室内植物和其他盆栽植物种植，许多病原体和害虫，传播病原体不暴露于天敌的条件下。 So they often go unchecked if they are already present in the soil.因此，他们往往听之任之，如果他们已经在土壤中。 In other cases, outdoor soil has been exposed to a disease that may stay in the soil for years.在其他情况下，室外土壤已经露出一种疾病，可能会留在多年的土壤。 Sterilizing the soil before planting anything in such soils may help reduce disease and pest problems.之前，任何在这种土壤种植的土壤消毒，可能有助于减少疾病和虫害问题。
Sterilizing soil removes not only the pathogens, but also the predator microbes that would normally keep the pathogens in check.消毒土壤移除不仅病原体，但也捕食微生物，通常会保持在检查病原体。 It also alters the structure and chemical makeup of the soil and kills beneficial microbes that work in symbiosis with the plant.它也改变了土壤的结构和化学成分，并杀死有益微生物与植物共生工作。 At best, they are a temporary solution, since pathogens travel by air, by flying insects, and on the surface of humans or animals that come in and out of the area.充其量，他们是一个临时的解决方案，因为病原体乘飞机旅行，飞虫，对进出该地区的人类或动物的表面。
Soil that is unable to support plant life, or very little of it, is also called sterile soil.土壤是无法支撑植物的生命，或只有极少，也被称为无菌土壤。 Not only are essential microbes missing, but there are also precious few nutrients in the soil.不仅缺少必要的微生物，但也有在土壤中的几个珍贵的营养素。 Climatic conditions, such as little to no moisture or constant sub-zero temperatures usually accompany the environment of sterile soil.气候条件，如几乎没有水分或零度以下的温度恒定，通常伴随无菌土壤环境。 However, soil that has been over-tilled, over-fertilized and overloaded with pesticides can become sterile as well, since chemical nutrients of fertilizers alone are only sufficient in such an overworked area if they are constantly applied.然而，土壤已被过度耕种，过度施肥和农药重载可以成为无菌为好，因为化学肥料单独养分只有在这样一个过度劳累的面积是不够的，如果他们不断应用。 Overworking the soil has the seemingly ironic effect of depleting it.操劳过度的土壤，消耗它似乎具有讽刺意味的??的效果。
