摘　　要：在四川金沙江干热河谷地带栽培的希蒙得木一年四季均可开花，但主要集中在1月～2月和6月～7月，而且仅春季开的花才可能授粉坐果。雄株开花时间早于雌株。在2a生时，植株开花率迭98％。影响希蒙得木开花坐果的主要气候因子是空气相对湿度。在旱季采取灌溉措施可以显著提高植株坐果率，种子产量是未灌溉植株的7倍以上。The trees of Sirnrnondsia chinensis Schneider plantations can blossom in any season of a year in the Jinsha River Valley, Sichuan, but mainly blossoming in periods of January and February and June and July. Only the female flowers which blossom in spring could be pollinated and bear seeds. The male flowers blossom earlier than the female flowers. The rate of blossom of trees at the age of two reaches to 98%. A statistical analysis indicates that the relative humidity of air is a key factor which affects pollinating and seed-bearing of Simmondsia chinensis Schneider trees. Seed yield of the plantation can be increased by irrigation during dry seasons.
