We present a calculation of the leading order QCD fragmentation functions for gluons to split into spin-triplet D-wave quarkonia. We apply them to evaluate the gluon fragmentation contributions to inclusive {sup 3}D{sub J} quarkonium production at large transverse momentum processes such as the Fermilab Tevatron and find that the D-wave quarkonia, especially the charmonium 2{sup {minus}{minus}} state, could be observed through the color-octet mechanism with present luminosity. Since there are distinctively large gaps between the contributions of two different (i.e., color-singlet and color-octet) quarkonium production mechanisms, our results may stand as a unique test of the NRQCD color-octet quarkonium production mechanism. {copyright} {ital 1997} {ital The American Physical Society}
