High yield techniques for gingkgoes with low yield

Abstract: Dozens of years of investigation showed that the low and unstable yield of gingkoes was caused mainly by the poor site condition , careless management , insufficient male stalks , and improper pollination .Since the 1970,s , via such techniques as delivery of fertilizer-applying , pruning and regeneration of old trees , aftificial pollination , and graft of male -flower twigs high up on the tree , the gingko yield has increased from 44.4 t in 1970,s to 85.2 t in 1980' s .The variation coefficients have likewise decreased , demonstrating a yield both high and stable .
