How to deal with earthworms: hot topics and practical guides on the Internet in the past 10 days
Recently, vermicomposting has become a hot topic in environmental, agricultural, and home gardening circles. This article combines the hot content on the Internet in the past 10 days to sort out the scientific treatment methods, application scenarios and practical data of earthworms to help you make efficient use of this "soil engineer".
1. Core Values of Earthworm Treatment
Earthworms improve soil by decomposing organic waste, and the way they are processed directly affects ecological benefits. The following are the three major directions that netizens have paid most attention to in the past 10 days:
| areas of concern | Proportion | Popular platforms |
|---|---|---|
| home composting | 45% | Xiaohongshu/Douyin |
| organic farming | 35% | Zhihu/Bilibili |
| Environmental protection project | 20% | Weibo/public account |
2. Comparison of earthworm treatment technologies
According to the latest research data from China Agricultural University (2023), the effects of mainstream processing methods are as follows:
| Treatment method | degradation cycle | Organic matter conversion rate | Applicable scenarios |
|---|---|---|---|
| traditional compost | 60-90 days | 40%-50% | large farm |
| Earthworm Tower | 15-20 days | 75%-85% | family balcony |
| commercial breeding | Continuous output | 90%+ | Organic fertilizer production |
3. Practical Guide to Home Vermicomposting
The 5 most popular steps under Douyin’s #zerowaste life topic:
1.Container selection: 20L plastic box with lid (drilled for ventilation)
2.Mat laying: Shredded newspaper + coconut bran (thickness ≥10cm)
3.Earthworm casting: Red earthworms 500g/square meter (average price on Taobao 25 yuan/jin)
4.Feeding management: Add 1kg of food waste per week (avoid citrus/greasy food)
5.harvest cycle: 10kg of high-quality vermicompost can be obtained in 2-3 months
4. Questions and Answers on Hot Topics in Earthworm Treatment
| question | High frequency answers | Data source |
|---|---|---|
| Will earthworms escape? | Keep the humidity at 60%-70% to prevent | Zhihu Zangzang 1.2w+ |
| Can pet waste be disposed of? | Dog and cat feces require pre-treatment (fermentation for 7 days) | Actual measurement of UP master at B station |
| How to maintain it in winter? | Foam box + straw insulation (above 5℃) | Agricultural technology extension station |
5. New trends in commercial applications
According to Qichacha data, there will be 317 new earthworm-related companies in 2023, mainly distributed in:
| Application areas | Typical cases | annual processing volume |
|---|---|---|
| food waste | An environmental protection company in Chengdu | 200 tons/day |
| Sludge treatment | Nanjing Ecological Project | Reduce heavy metals by 35% |
| Medicinal breeding | Hebei base | Earthworm protein extraction |
Conclusion
As an important part of the circular economy, earthworm processing not only complies with the "double carbon" goal, but also creates actual economic value. It is recommended that household users start trying composting on their balconies, and companies can focus on large-scale organic solid waste treatment technology. Continuing to pay attention to cutting-edge developments such as earthworm gene editing (research has been launched in the United States) will lead to more efficient biological treatment solutions.
