- 摘要:
- 以单株核桃为研究对象，通过花粉收集的方法分析了核桃雄花散粉期,花粉通量与散粉时间、传播距离、飘浮高度和气象因子的关系，以了解新疆南疆盆地核桃雄花散粉期花粉飞散时空格局及其影响因素。结果表明：新疆南疆盆地核桃雄花散粉持续时间约为1周，一日内12:00—14:00花粉通量最大；水平方向上花粉通量受风向影响，且随传播距离的增大逐渐减小；垂直方向上随高度的增加花粉通量逐渐减小；花粉通量与气温呈极显著正相关（P＜0.01），与风速呈显著正相关（P＜0.05）。花粉通量大小主要受气温和风向、风速的影响。
- Abstract:
- Individual plant of walnut was used as test material and by receive pollen that carried about walnut pollen influx which contains diurnal variation,the pollen of the horizontal,vertical distribution and propagation distance,and then analyzed the relationship between the pollen influx and meteorological factors in pollinating period.In order to comprehend the spatial-temporal patterns and influencing factors of walnut pollen influx in pollinating period in southern Xinjiang basin.The results showed that the walnut powder period last about a week,and walnut pollen influx was maximum during 12:00—14:00 in southern Xinjiang.Horizontal pollen influx affected by the direction of the wind,and along with the increase of propagation distance it gradually decreased.Pollen influx was inversely proportional to the height in the vertical direction.Pollen influx were extremely significant positive correlation with the temperature (P＜0.01),and the wind speed was significantly positive correlation (P＜0.05).Pollen influx influencing factors mainly are wind direction,wind speed and temperature.
