act Woodruff和siddoway(1965)建立了估算风蚀土壤流失量的方程，称为风蚀方程(wind erosion equation, WEQ);该方程的解给出了在某些野外条件下的最大风蚀量，并被认为是确定在这些条件下处理风蚀的必要方法的证据(Eltaif et al.，1991)。本研究旨在利用(woodruff and siddoway, 1965)方程，找出伊拉克南部Samawah地区和伊拉克中部巴格达34年间气候变化对土壤风蚀损失量的影响程度，以及土壤表面粗糙度因子的变化对减少或增加土壤风蚀损失量的有效性。选定的两个地点位于伊拉克中部和南部地区，一个在巴格达省的Al-Jadiriya地区，另一个在Al-Muthanna省的Samawah地区。结果表明，Al-Jadiriya地区1980-2013年土壤流失量每年减少10-30 kg.hec. 1。而samawah每年增加240-760公斤。研究期间，地表粗糙度因子对减少土壤流失量的作用显著。与非垄土相比，垄土的粗糙度系数(0.5)减少了2.6倍的土壤流失量(1)，半桥土的粗糙度系数(0.75)为65%。这是由于桥梁在降低风速和降低其侵蚀力方面的作用。土壤流失量的总方向为Al-Jadiriya地区减少，Samawah地区增加，在土壤流失量的总方向线上下波动的情况下，受土壤流失量总方程中的气候因子(C)的影响，土壤流失量反映风蚀能力，湿润条件改善时土壤流失量减少，降雨增加，蒸发减少，干燥条件下土壤流失量增加。E-mail(mohammed.alrawi@coagri.uobaghdad.edu.iq)版权所有

"A factorial experiment with completely randomized design (CRD)with three replicates was carried out at agronomy laboratory of the Directorate of seed testing and certification / Branch of Salahaldeen to study the effect of salinity levels of irrigation water )0 ،1.75 and 2 Mm ) and grains affected by the use of mechanical seeds in seed germination and seedling growth for two varieties of wheat bread(IPA99 and Sham 6). The characteristics of germination percentage ،speed germination ،length of plumule and radical ،pure live seed percentage and seed vigor studied. The observed results are as follows: Significant differences are found between cultivars. (IPA99) cultivar gave the highest tolerance to water salinity and seed fracture. However ،salinity levels and seed fracture caused a significant decrease in all features. As for interactions ،cultivars and seed mechanical damage interactions were significant in all characteristics. While the interactions of varieties and levels of salinity were significant in the characteristics of the speed of germination and length of plumule . Interactions of salinity levels and seed mechanical damage did not reach the significant limit except for the characteristic of the plumule’s length, which reached the highest value at 7.697 cm . At the same time, the triple interactions (cultivars ،seed mechanical damage and levels of salinity) were significant except for both germination percentage and pure live seed percentage. The best triple interaction was (IPA99) with 1.75 Mm and undamaged seed, which gave the best values in: germination percentage ،length of plumule and radical ،pure live seed percentage and seed vigor. The values of the above were as follows: 98.67% ،8.707 cm ،10.01 cm ،94.72 ،18.45 respectively."

The treatment of plant spraying with selenium at a concentration of 20 mg L-1 led to an increase in the fertility rate. By 12.91%, this treatment increased the grain yield by 69.23%. This is as a result of its superiority in the characteristic of the length of ear, the number of active ear, the number of rows in the ear, the number of grains in the row, the number of grains in ear and the number of grains in plant.
