[目的]探究核桃雄花散粉规律，为提高核桃产量及品质奠定基础。[方法]通过重力载玻片法收集花粉，对新疆两个主栽核桃品种：‘新新2’和‘温185’的散粉规律进行了研究。[结果]结果表明：核桃雄花序开花散粉持续10 d左右，日平均温度在20-24℃条件下，集中散粉时间为4d左右，一般树冠东、南及中部位置的散粉量较大；温度在19-27℃范围均可散粉，散粉的适宜温度为20-23℃。[结论]核桃散粉规律与温度密切相关，适宜的温度条件下，散粉呈现爆发性。

[Objective] The aim was to find out the regularities of powder scattering about walnuts’ male for improving walnut yield and quality. [Method] The powder was col ected by the method of gravity glass slide, and the regulation of powders scattering of ‘Xinxin2’ and ‘Wen185’ which were the two main cultivated varieties of walnut in Xinjiang were studied. [Result] The results showed that the male inflo-rescence powder lasted for around 10 d, and centralized scatter powder was about 4 d, when walnut male at the daily mean temperature was from 20 to 24 ℃. Gen-eral y, the large powder shedding amount was in east, south and central position of crown, in the range of 19 to 27 ℃, and the optimal temperature of powder scatter-ing was 20 to 23 ℃. [Conclusion] The pol ens scattering regularities of walnut is closely related to temperature. With a favorable temperature, powder scattering per-forms outstandingly.
