How do I delete items from the ground?

I'm building a server with friends in minecraft. He is on the java edition 1.14. But what command must I write in command block that all items lying on the floor are deleted? Or is there a command of the items immediately if you put them away?

I'm not sure, but I think Command was called / kill @e [type = item]

Kill @e [type = item]

Try it with / gamerule randomTickSpeed [value] maybe that works.

Huh? That only increases the tick speed! As trees grow and so faster and plant and that's it

And items are also faster

But takes too long and far too many disadvantages

Did not know anything else fast and who knows what she has in mind on her server…
