Primary school teacher raises earthworms

(Baonghean.vn)- In the mountainous commune of Thach Son, Anh Son district (Nghe An), teacher Nguyen Thi Thuy built a model of raising earthworms to produce biofertilizer with high efficiency.

Although she is a primary school teacher, with her passion for agricultural production, Ms. Nguyen Thi Thuy has diligently studied books, documents and visited models in Cu Chi district - Ho Chi Minh city about the process of producing organic fertilizer from raising earthworms. After accumulating knowledge and experience, Ms. Thuy discussed with her family to rent over 1 hectare of land in the Lam River area in village 7, Tuong Son commune to implement the model.

Ms. Thuy said: At first, the family raised them on an area of ​​240 m2.²Thanks to proper care, the worms have grown strongly. From the initial source of seeds, she doubled, then tripled... currently the family's earthworm farming area has reached 0.5 hectares.

Ms. Nguyen Thi Thuy shares her experience: Raising earthworms is very easy because this is an animal that easily adapts to the environment and has a fast reproduction rate. The source of raw materials for raising earthworms is taken advantage of from livestock manure and agricultural by-products such as straw, corn stalks, etc. For the worms to grow well, the breeder also needs to build plots, earthworms like the dark, so during the raising process, they must be covered with tarpaulin to ensure humidity, avoid sunlight and also to prevent species such as toads, frogs, mice and insects from entering the garden.

During the breeding process, 20kg of seeds are needed per 1m.^2,Every 2-3 days, feed the worms directly and water them regularly to ensure good growth conditions. Applying this method, after 1 month, you will have biofertilizer to harvest. In addition to producing bioorganic fertilizer, Ms. Thuy also invested in a machinery system to produce worm juice to provide food for shrimp farms.

Currently, with an area of ​​0.5 hectares, each day Ms. Nguyen Thi Thuy's worm farm can supply the market with 2 tons of biofertilizer and 500 liters of worm juice.

According to Ms. Thuy, among organic fertilizers, earthworm manure is the most popular among farmers because it is rich in nutrients and stimulates plant growth. In particular, unlike manure, earthworm manure is easily absorbed and increases the ability to retain water in the soil, preventing root diseases.

Vermicompost adds nitrogen-fixing, phosphorus-decomposing, cellulose-decomposing microorganisms and disease-resistant microorganisms. Therefore, vermicompost has the effect of improving soil, reducing the use of chemical fertilizers, stimulating seeds to germinate quickly and evenly and is suitable for all types of crops, especially creating clean products in agricultural production.

Currently, the earthworm farming model for biofertilizer of Ms. Thuy's family is visited by many people to learn from the experience, because the investment capital for raising earthworms is not large, the income is quite good, but farmers need to combine it with raising livestock and poultry to make full use of food sources and waste, increasing economic efficiency.
