The results of calculations showed that the maximum increments in saltation height and horizontal distance due to the Magnus force were 10.2 and 24.9%, respectively, and that both increments increased with increasing lift-off angle. The maximum increments in saltation height and horizontal distance of sand grains caused by the Saffman force were only 4.6 and 3.7%, respectively. The vertical concentration distribution of Aeolian sand flow follows exponential function distribution whether or not force analysis of saltating sand grains includes Magnus and Saffman force. The effect of Magnus and Saffman force on the vertical concentration distribution of Aeolian sand current makes the rate decrease near sand bed and it is consistent with the effects of Magnus and Saffman force on the saltation height and distance of sand grains.
Magnus力对跃移高度和水平距离产生的最大增量分别可达到10.2%和24.9%,这两个增量均随起跃角度的增加而增大;Saffman力对跃移高度和水平跃移距离产生的最大增量分别为4.6%和3.7%;是否考虑Magnus与Saffman力,风沙流垂向质量百分浓度均服从指数函数分布,Magnus与Saffman力使得风沙流垂向质量百分浓度较不考虑它们的作用呈现出底层的比例较小,上层较大,Magnus与Saffman力对跃移高度的影响基本与其对风沙流垂向质量分布的影响一致,不过Magus力对风沙流垂向质量百分浓度分布影响较大,0-2cm范围内尤为强烈(7.16-10.81),其他高度层(2-20 cm)的影响相对较小(0-2.95)。

The twig production of different clones is different, from 5.5 twigs per month to 14.8 twigs per month. The rooting rate, root number and root length change regularly as the concentration of IBA goes up from 0.05 to 2.00 mg/L. At the concentration of 0.05 mg/L ppm IBA, rooting rate and root length are the highest. Cutting substrate also has eminent effect on rooting rate and survival rate, 50% peat plus 50% sub-top soil is the best substrate. The survival rate differs greatly among clones, from 56.7% to 90.0%. Rooting rate and survival rate change regularly as season changes. The rooting rate of May and June is middle, that of July and August is high and that of September and October drops rapidly. The survival rate is low in May, September and October and high in June, July and August.
