The cross sections for the principal channels of production of two and four strange particles in all charge states are determined by measuring the cross sections of neutral strange particles with S = +- 1. Corrected for the cross sections of the channels with ..xi.. hyperons, the inclusive cross section for production of a pair of strange quarks is 11.06 +- 0.66 mb. The cross section for the production of two pairs of strange quarks is 0.52 +- 0.17 mb. It is shown that in p-barp annihilation the strange particles are produced mainly upon annihilation of one pair of valence quarks.
