陈闻礼:什么是无菌的盆栽土壤吗？

Benefits优点

• Sterile potting soils have no active weed seeds, insects or disease organisms, which allows you to grow healthier plants.无菌盆栽土壤有没有活跃的杂草种子，昆虫或疾病的生物体，它允许你长出健康的植物。 The sterilization process, called pasteurization, uses heat to kill or neutralize any pests living in the soil.称为巴氏杀菌，灭菌过程，利用高温杀死或抑制任何生活在土壤中的害虫。 Chemical sterilization is also used for some commercial soils.也可用于一些商业土壤化学灭菌。 Seeds started in sterilized soil are less prone to damping-off disease and other fungi that kill the young plants.不易发生猝倒病和其他真菌杀死年轻的植物种子消毒土壤开始。

Commercial Mixes商业混合

• Commercial potting mixes usually combine sterilized potting soils with naturally sterile mediums, such as a peat moss or vermiculite.商业培养土的包装袋与自然无菌介质，如泥炭藓或蛭石，通常结合盆栽土壤消毒。 Not all commercial mixes have undergone sterilization, so it's vital to check that the soil mix is labeled sterile or pasteurized.并非所有的商业混合进行杀菌，所以它的重要的检查，土壤结构为无菌或经消毒的。 If you prefer purchasing compost over traditional potting soil mixtures, it must also undergo sterilization procedures and should be labeled as such.如果你喜欢购买堆肥比传统的盆栽土壤混合物，它也必须接受绝育手术的，应该打成这样。 Using a nonsterile soil, in either pots or garden beds, can introduce weeds seeds and pathogens to your garden.使用未经消毒的土壤，无论是盆或花园床，可以介绍你的花园里的杂草种子和病原体。

Homemade Mixes自制混合

• Unless you assemble your homemade potting mixes with sterile purchased components, you must heat treat any soil or compost before planting.除非你组装你的自制培养土，用无菌购买组件，您必须热处理任何播种前的土壤或堆肥。 Peat moss, vermiculite, perlite and other mineral potting soil amendments are already sterile and shouldn't be heat treated.泥炭土，蛭石，珍珠岩和其他矿产盆栽土壤改良剂已经无菌，不应该进行热处理。 Baking moistened compost and garden soil at 180 degrees Fahrenheit for 30 minutes kills most weed seeds and disease organisms, making these components sterile for use in your homemade potting recipes.烘焙沾在华氏180度的堆肥和园土30分钟杀死大部分杂草种子和疾病的生物体，在您自制的灌封食谱，这些组件使用无菌。

Keeping Soil Sterile保持土壤消毒

• Both purchased and homemade sterile soils must remain sterile until they are planted.无论是购买和自制的无菌土壤必须保持无菌，直到他们种植。 Storing the soil in sealed bags or plastic tubs prevents pathogens and insects from compromising the safety of the soil.储存在密封袋或塑料浴盆的土壤，防止危及安全的土壤，病原体和昆虫。 Reused pots and garden tools may also transfer unwanted pests to sterilized soil.重复使用盆和园林工具，也可将不需要的害虫消毒土壤。 Cleaning these items with a weak bleach solution sterilizes them so they do not infect otherwise healthy potting soils.这些项目与弱的漂白剂溶液清洗消毒，以便它们不感染其他健康的盆栽土壤。 Heat treatment sterilizes used potting soils, but should not be used on soils containing vermiculite or perlite as these minerals respond poorly to heat.热处理消毒用于盆栽土壤，但不应该使用含有蛭石，珍珠岩的土壤上，因为这些矿物质不良反应热。
