It seems we can expect this launch in August or so.

遥感卫星总体部抓总研制的高分十一号03星正在紧张地开展D阶段测试,为保证卫星能够按期出厂,“五一”期间相关科研人员均到岗工作,再次展现了“紧抱成团、亲密无间”的团队精神风貌。
The Gaofen 11 03 satellite developed by the General Department of Remote Sensing Satellites is now intensively carrying out Phase D testing. To ensure that the satellite can be shipped on schedule, relevant scientific researchers will be on duty during the "May 1st" period. Team spirit of “group and closeness”.

China launches new satellite
Source: Xinhua| 2021-11-20 13:38:54

TAIYUAN, Nov. 20 (Xinhua) -- China launched a new satellite from the Taiyuan Satellite Launch Center in the northern province of Shanxi on Saturday.

The satellite, Gaofen-11 03, was launched by a Long March-4B rocket at 9:51 a.m. (Beijing Time) and entered the planned orbit successfully.

Developed by the China Aerospace Science and Technology Corporation, the satellite will be mainly used for land surveys, city planning, land rights confirmation, road network design, crop yield estimation and disaster prevention and mitigation.

The launch marked the 397th mission for the Long March series carrier rockets.

Is there any significance to the blossoms and fruit in the patch artwork?

The fruit looks like pomegranate. In China the pomegranate "was considered an emblem of fertility and numerous progeny."

A Chinese Chang Zheng 4B rocket successfully launched the Gaofen 11-03 satellite to sun-synchronous orbit this morning. It was the 44th orbital launch attempt from China this year.

Too many errors in the text.
Each of the following statements is wrong:

Gaofen 11-03 is the third in a series of high-resolution optical imaging Gaofen 11 satellites, part of the wider Gaofen series which aims to provide China with a global high-definition Earth-imaging capability for civil applications.
The first such satellite, Gaofen 11-01, was launched in July 2016.
The Gaofen 11 satellites operate in sun-synchronous orbits, with a perigee of approximately 450 kilometers, an apogee of around 690 kilometers...

And this one has no proof:
Pad 7 continues to be used for suborbital Chang Zheng 2C launches in support of military projects.

1. Gaofen 11-03 is the third in a series of high-resolution optical imaging Gaofen 11 satellites, part of the wider Gaofen series which aims to provide China with a global high-definition Earth-imaging capability for civil applications.
2. The first such satellite, Gaofen 11-01, was launched in July 2016.
3. The Gaofen 11 satellites operate in sun-synchronous orbits, with a perigee of approximately 450 kilometers, an apogee of around 690 kilometers...

And this one has no proof:
4. Pad 7 continues to be used for suborbital Chang Zheng 2C launches in support of military projects.

Let me elaborate:

1. This is caused by the Chinese "muddling waters" by reusing the Gaofen names that started out with 7 series of civilian Earth observation satellites (GF-1 to 7) for other ones that details were not disclosed (8 through 14). Though IIRC I have seen Chinese discussions that this name was used instead of the Yaogan series due to them having a different (government) customer, which could potential make them "semi-civilian".

2. Should be typo for 2019.

3. See Jonathan McDowell's summary: https://twitter.com/planet4589/status/1461889946990563333?s=20

4. IIRC this was an educated guess based on observations of the "rocket signs" at the launch record insignia plate that could be found on the bottom of LC-7's tower some years ago (https://forum.nasaspaceflight.com/index.php?topic=5689.msg1433449#msg1433449). It was, indeed, a guess, even if it seems plausible.

2. Actually 2018.
3. 246x696 km (initial), 495 km circular later.
4. LC-9 launch record insignia plate lists two non-orbital launches per year in 2016, 2019, 2020 and 2021.
