How to write an observation record of green beans is as follows:

1, Title: observation record of green beans.

2, Date: XXXX year XX month XX.

3, observation object: green beans.

4, observation environment: indoor, temperature 25 degrees Celsius, humidity 60%.

5, the purpose of observation: to observe the germination and growth process of mung beans, in order to understand the growth pattern of plants and the impact of environmental factors on growth.

I. Observation Process:

1. Preparation Stage: Select some full mung beans, clean them, and soak them in water for about 8 hours until they become slightly swollen.

2. Germination stage: Drain the mung beans and distribute them evenly in a pot that has been lined with moist soil. Then place the pots in a cool and ventilated place. Water every 6 hours to keep the soil moist.

3. Growth Stage: In the next few days, the mung beans begin to germinate and gradually grow small bright green leaves. The number of times you water each day can be appropriately reduced, but make sure the soil stays moist. At the same time, you can start to receive sunlight, but do not be exposed to strong direct sunlight.

4. Fruiting Stage: After about a week, the green beans begin to bloom and bear fruit. At this point, you need to continue watering, but do not let the pots become waterlogged. At the same time, you can move the pot to a slightly more open area in order to give the green beans better light and ventilation.

2. Observations

1. Mung beans have high requirements for temperature and humidity during germination and growth. Under suitable temperature and humidity conditions, mung beans will germinate and grow very rapidly.

2, adequate sunlight is also very important to the growth of mung beans. In full sunlight, the leaves of mung beans will be more green and the flowers will be more colorful.

3, In the process of observation, we also found that mung beans absorb a lot of nutrients, especially nitrogen and phosphorus, during their growth. This shows that when planting mung beans, adding nutrients appropriately can promote their growth.

Summary

Through this observation, we learned that the growth process of plants is a complex process affected by many environmental factors. Proper temperature, humidity, sunlight and nutrients are the key factors to promote plant growth. We also learned that mung beans need careful care and management during germination and growth to ensure their normal growth and development.
