pinch-row compaction如何理解?

Chinese translation:土壤的轮迹状压实
Explanation:
在网上找到这么一段解释:

Some important things to remember:
• Most compaction is caused by equipment traffi c
• Up to 80% of compaction in the fi eld occurs on the
fi rst pass of the season
• Surface compaction is caused by high ground
pressure created by reduced contact area
• Deep compaction is caused by high axle loads
• Slip compaction is caused by low surface contact
areas and shearing of the topsoil
• Pinch-row compaction is caused by dual or triple
wheels as ground pressure from the tyres shifts from
the centre of the tyre to the outside
• Compaction can be reduced in two ways: mechanical
techniques and controlled traffi


由此可见,这种压实是由于农用机械的轮子引起的,在轮子下的泥土被挤向外侧,可以想见,会在机械后留下两条微微隆起的泥土车迹,而在轮子经过的正下方区域,则会微微下凹。

agree  Oceanwide: 行车时,并排的两个或三个轮子之间,会形成一条条的垅状隆起,即两边的轮子一夹,pinch出了一条条的脊,与车辙相间成为并排的“row”,因为是"pinch"出来的,所以一条条的车辙与脊都非常密实。
