[Objective] The research aimed to use barax, ammonium molybdate and lanthanum nitrate trace fertilizes to regulate the blossom of Schisandra chinensis (Turcz.) Baill. and analyze their influences on yield. [Method] The completely randomized block design of 9 treatments was introduced in this study that including low, middle and high concentration treatments of barax, ammonium molybdate, and lanthanum nitrate trace fertilizers, concentration of which were 2 000, 4 000 and 6 000 mg/L, 1 000, 3 000 and 5 000 mg/L, 100, 300 and 600 mg/L respectively, distilled water as control. [Result] The high concentration treatment of lanthanum nitrate trace fertilizer was the best in improving the total number of flowers of Schisandra chinensis (Turcz.) Baill., increasing by 53.02% compared with CK, yet it could not effectively regulate the proportion of male and female flower. The middle concentration treatment of barax could raise the number of female flowers and the yield of Schisandra chinensis (Turcz.) Baill. most effectively, increasing by 151.76% and 65.43% respectively than CK. Ammonium could increase the total number of flowers, female flower and the yield compare with CK. But the increasing quantity was not obvious as borax and lanthanum nitrate. [Conclusion] The study can provide effective technological measures for improving the female flower rate and yield of Schisandra chinensis (Turcz.) Baill.
