- Observation At night, air temperature in the naked field was lower than in other fields.
- Observation Morning air temperature was considerably low on the west side of south-north ridges and north side of east-west ridges.
- Observation Afternoon air temperature was low on the east side of south-north ridges and north side of east-west ridges.
- Observation At the lower half of wheat height, air temperature exceeded that in the naked field.
- Observation Morning ground and underground temperatures were lower on the west side of south-north and north side of east-west ridges.
