C. Remember

- Identify foods that can and cannot be fed to worms: avoid feeding worms plants that are sour, spicy, astringent...

- The place where food is stored for worms must have a roof to limit direct sunlight or rainwater seepage.

- Agricultural by-products: if not yet rotten (fresh, dry), must be cut into 5-10 cm pieces before composting, if rotten, put directly into the compost pile.

- The mixing ratio of agricultural by-products does not exceed 50% of the raw material mass, to ensure that the worm food has enough protein.

- For fresh cow manure, just add water and leave it for a few days before feeding it to worms.

- For other types of livestock and poultry manure and agricultural by-products, they must be composted.

- For organic waste: feed worms directly or compost.

- Waste from biogas digester: used directly for worms to eat.

- When composting, add biological products to make the food decompose faster and smoother.

MODULE TEACHING GUIDE

I. LOCATION AND PROPERTIES OF MODULES

1. Position: The module “ Preparing for vermiculture ” is the first module in the elementary vocational training program “ Vermiculture from livestock and poultry manure and agricultural waste”; teaching this module is intended to create a premise for teaching the following modules of the program. This module can also be taught independently according to the needs of the learners.

2. Characteristics: This is a specialized module, integrating theoretical knowledge and practical skills in performing tasks such as: Surveying conditions for raising worms; Creating substrate for worms; Collecting and processing food for worms. To improve the quality of vocational training, this module needs to be carried out right at livestock facilities and agricultural farms.

II. MODULE OBJECTIVES

1. Knowledge

- Analyze the situation of raising and consuming earthworms to make a plan for raising earthworms;

- Describe the biological characteristics of worms;

- Describe the methods of processing and handling of substrates;

- State the steps for selecting, collecting and processing food for worms.

2. Skills

- Survey water sources and food for worms;

- Processing and handling of substrates properly;

- Choose the right food for worms;

- Collect, preserve and process worm food properly.

3. Attitude

Be aware of complying with technical procedures when performing work to ensure labor safety and environmental hygiene.

IV. INSTRUCTIONS FOR DOING EXERCISES AND PRACTICES

At the end of each lesson in the module, there are questions and exercises/practices. Depending on the questions or exercises/practices, the teacher divides the students in the class into groups of 3-5 students or each student works independently to answer the questions in the form of multiple choice. Do the exercises/practices according to the steps to get the product according to the requirements of the topic.

1. Instructions for answering questions

Teachers prepare questionnaires to distribute to students;

After giving questions to students, the teacher and the whole class review or discuss theoretical content related to the questions;

The teacher instructs students to circle the correct answer to the question. When the time is up, the teacher instructs students to cross-grade each other's work, then the teacher comments and evaluates the results of the students' work.

2. Instructions for performing exercises/practices

In order for students to do exercises/practices, teachers distribute appropriate topics, materials, and tools to students/groups of students and disseminate the method and time of implementation, and the results of the exercises/practices that must be achieved.

During the process of students doing exercises/practices, teachers observe, remind and correct in a timely manner so that students perform correctly, complete all steps, have enough quantity and achieve quality of exercise/practice products. When the time is up

do exercises or practice, teachers comment, compare with answers, evaluate and score for students or groups of students.
