EM1 means Effective Microorganism One
在农业领域里,“EM1”通常是指 有效微生物菌液第一号(Effective Microorganisms 1),这是由 Teruo Higa 在 Japan 开发的一种有益微生物混合液。它被广泛应用于:自然农法有机农业堆肥园艺畜牧业土壤改良
EM1里面有什么?
EM1含有许多有益微生物,例如:
乳酸菌,酵母菌,光合细菌,发酵菌类与其他有益微生物
这些都属于“好菌”,能够帮助改善土壤与有机物的生态环境。
农民通常会把EM1用水稀释,有时再加入糖蜜(molasses)活化后,喷洒在:土壤,作物,堆肥,畜禽,粪便,水池等地方。
为什么农民喜欢使用EM1?农民使用EM1,主要是为了改善土壤生态,并减少对化学农药与化肥的依赖。1. 改善土壤健康. EM1能增加土壤中的微生物活动。健康的微生物能够:更快分解有机物。 提高养分吸收。让土壤更加松软肥沃。2. 促进植物生长。有些农民发现使用EM1后:根系更强壮,叶子更翠绿,作物长势更好,产量提高。尤其是在长期使用化肥、导致土壤微生物受损的土地上。3. 减少恶臭与腐败。
EM1常被用于:堆肥场,畜牧场,粪便处理系统。因为它能促进“发酵”而不是“腐烂”,从而减少臭味。4. 加快堆肥速度。EM1能加速分解:树叶稻草厨余动物粪便。
因此能更快制成堆肥。5. 减少化学肥料使用。有些农民利用EM1来减少:化学肥料,农药,除草剂。不过效果会因土壤条件与管理方式不同而有所差异。
为什么叫“EM1”?
“EM”是 Effective Microorganisms(有效微生物) 的缩写。
“EM1”是原始浓缩菌液。
农民通常会把EM1与:水,糖蜜。混合后发酵几天,制成“活化EM”:
Activated EM,AEM,然后再使用。
EM1真的有效吗?
对此有不同看法。支持者认为:土壤更健康作物更强壮病害与臭味减少更符合永续农业理念质疑者认为:科学证据并不完全一致效果非常依赖土壤条件与管理方式有些效果可能只是因为增加了有机质
不过实际上,很多自然农法与有机农民仍然喜欢使用EM1,因为它成本低、风险小,而且操作简单。
活化EM(AEM)的常见制作方法
材料,1. EM1 原液。市售EM1。2. 糖蜜(Molasses)黑糖蜜最好。没有的话,也有人用:黑糖,红糖,黄糖。但效果可能略差。3. 无氯水。最好是:井水雨水放置24小时以上的自来水因为氯会杀死微生物。见比例。很多农民使用:EM1:1份糖蜜:1份水:18份。例如:EM1 1公升,糖蜜 1公升,水 18公升。总共约20公升。
制作步骤
第一步:混合。先把糖蜜溶于温水中(不要太热)。然后加入EM1。第二步:密封发酵。装入塑胶桶。注意:尽量减少空气,盖紧,但每天稍微放气一次。因为发酵会产生气体。第三步:发酵。放在温暖阴暗处。
通常:夏天:5~7天冬天:7~14天。怎样算成功?成功的活化EM通常:有酸甜发酵味。像酸菜、酵素、优格那种气味。pH 大约 3.5 以下颜色通常:黄褐色,深棕色。什么情况表示失败?如果出现:
臭味,腐败味,发霉(特别是黑霉、绿霉)pH太高
通常表示坏菌污染。
如何使用?土壤喷洒
常见稀释比例:1:100 ~ 1:500 例如:100 c.c. 活化EM,加10公升水
喷土壤或叶面。堆肥。可直接喷在:厨余落叶动物粪便。帮助发酵。除臭。很多农场喷在:猪舍鸡舍排水沟,减少臭味。为什么EM会有效?原理主要是:有益菌大量繁殖后,会压制:腐败菌部分病原菌
同时帮助有机物发酵分解。简单讲,就是:“用好菌去抢地盘。”
In farming, “EM1” usually refers to Effective Microorganisms 1, a liquid mixture of beneficial microbes developed by Teruo Higa in Japan.
It is used in natural farming, composting, gardening, livestock care, and soil improvement.
What is inside EM1?
EM1 contains living beneficial microorganisms such as:
Lactic acid bacteria
Yeasts
Photosynthetic bacteria
Fermenting fungi and microbes
These microbes are considered “good bacteria” that help create a healthier biological environment in soil and organic matter.
Farmers usually dilute EM1 with water and sometimes molasses before spraying it on:
soil
compost
crops
animal waste
ponds
Why do farmers use EM1?
Farmers use EM1 mainly to improve soil biology and reduce dependence on chemicals.
1. Improve soil health
EM1 helps increase microbial activity in the soil.
Healthy microbes can:
break down organic matter faster
improve nutrient availability
make soil softer and more fertile
2. Better plant growth
Some farmers report:
stronger roots
greener leaves
improved crop vigor
higher yields
especially when soil life has been damaged by heavy chemical use.
3. Reduce bad smell and rot
EM1 is often used in:
compost piles
animal farms
manure systems
because it can reduce foul odors by encouraging fermentation instead of putrefaction.
4. Compost faster
EM1 speeds up decomposition of:
leaves
straw
kitchen waste
manure
This helps create compost more quickly.
5. Reduce chemical fertilizer use
Some farmers use EM1 to reduce:
synthetic fertilizer
pesticides
herbicides
although results vary depending on soil condition and farming practices.
Why is it called “EM1”?
“EM” means Effective Microorganisms.
“EM1” is the original concentrated microbial solution.
Farmers often make a secondary activated form called:
EM Activated Solution
AEM (Activated EM)
by mixing:
EM1
molasses
water
and fermenting it for several days.
Does it really work?
There are mixed opinions.
Supporters say:
soil becomes healthier
crops become stronger
less odor and disease
more sustainable farming
Critics say:
scientific evidence is inconsistent
results depend heavily on soil and management
some benefits may come simply from adding organic matter
In practice, many organic and natural farmers still like using EM1 because it is relatively inexpensive and low risk.
Here are some common farming uses of EM1:
