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.
