Methods of planting green beans for elementary school students in grade 4 are as follows:

1, Preparation

Before planting green beans, you need to make the following preparations:

Preparation of seeds: choose full, intact mung bean seeds, which can be purchased at the farmers' market or gardening store.

Preparing the soil: choose a patch of land or pot that is suitable for green beans and loosen it. If the soil is too hard or dry, add some organic matter (such as decaying leaves or compost) to improve the soil quality.

Preparation tools: you will need some gardening trowels, water jugs and fertilizer.

2. Planting Steps

Fluffing Soil: Use a gardening trowel to loosen the soil to make it looser.

DIGGING PITS: Dig a number of small pits in the soil according to the number and spacing of the green bean seeds. Space each pit at a moderate distance from each other to allow the green beans to grow and absorb nutrients.

Putting in the seeds: put the mung bean seeds into the small pits and gently cover the seeds with soil.

Watering: pour a moderate amount of water over the soil where the mung bean seeds have been planted to keep the soil moist.

Fertilizer: you can apply some fertilizer to promote the rapid growth of green beans as they grow.

3, maintenance management

In the process of green beans growth, you need to do a good job of maintenance management:

Watering: in the hot weather, you need to water every day to prevent the soil from drying out.

Weeding: timely weeding to prevent weeds from robbing nutrients.

Trimming dead leaves: If you find any dead leaves or branches, trim them in time to prevent them from affecting the growth of green beans.

Picking green bean pods: Pick green bean pods when they become full and the beans inside are larger. Just gently pinch the pods with your fingers and twist them off gently.

The fun of planting:

1. Observation and discovery: Growing mung beans is a process full of exploration and discovery. You can observe the process of germination and growth of mung beans, and discover how they turn from a tiny seed into a lush green plant that eventually bears fruit. In this process, children can learn a lot about plant growth and natural environment.

2. Labor and Achievement: By planting green beans, children can experience the fun of labor. They need to water, fertilize and weed the plants, and these activities can make them feel fulfilled and accomplished. When they see the fruits of their hard work--thriving green beans, they will feel very happy.

3. Cooperation and sharing: Growing green beans can also be a great teamwork project. Children can divide up the work and work together to complete the task. They can discuss together how to plant, how to solve problems, and also share the fun and results of the planting process together. In this process, they can not only learn a lot of knowledge, but also enhance the ability of teamwork.
