Mg,

Most varieties of jujube are self- fertile.

Okay, thanks. I read an article about Sherwood maybe only being partially self-fertile so I was wondering. If they are pollinated by wind it would seem that having two cultivars close together would help.

Most self-pollination info is somewhat unreliable, to get the really accurate data would require a lot of work of bagging flowers etc, and its more collected wisdom that is used.

My take on the jujube data is you may get better set with pollination but will almost surely get some fruit set without. I have problems with fruit set in spite of a lot of pollinators.

When I start with the Li variety a few years ago I didn't get fruit for three years. So I grafted other varieties and been getting a decent crop. I also have a potted Li that I had far away from the tree in a greenhouse, it set a big crop with out a pollinator. So, it's really hard to understand their pollination requirement.
Most jujube seeds are hollow which means they weren't pollinated.
Bottom line, it will not reliably set fruit with no pollination.

Jujubi plants are polinated by bees. They do best when there are two varieties to allow cross polination. Native bees polinate about 300 feet from their nests. Honey bees at least a mile. So the distant between your jujubi is not so important if they are both within say 100 feet of each other. You will probably get the best results if they are 10-20 feet apart. Build yourself a mason bee box near the trees and they will polinate your trees early and well.

I wouldn't say that the bees are main pollinators. Wasps and ants do the main job with a little help from a stray beetles.
Jujube flower structure isn't really made for bees.
