| 1. | It would appear that the inputs are insufficient to offset the mobilization and leaching of calcium from the topsoil .
钙的转入量看来不足以补偿从表土中活化和淋失的钙。 |
| 2. | Effect of acid rain on leaching loss of nitrogen and phosphorus
酸雨对紫色土氮磷淋失的影响 |
| 3. | Nitrogen leaching in soil and recommendation of nitrogen and irrigation
冬小麦土壤无机氮淋失规律及灌水施氮量的推荐 |
| 4. | Application of nitrogen leaching losses mixed simulative model in tile effluent from the drained paddy rice field
暗管排水稻田中氮素淋失动态混合模型及应用 |
| 5. | Leaching of no3 - - n with different fertilizer sorts can be divided into three stages : equilibrium , ascending , descending
应用方程iny : = a + blnt可拟合钾肥在砖红壤中120em处的淋失过程。 |
| 6. | Over - irrigation not only wastes water but could result in leaching of fertilizer ( primarily n ) below the root zone
过量灌溉不仅浪费水资源而且还可能引起肥料向根区以下的淋失(主要是氮素) 。 |
| 7. | Denitrification , on the other hand , can be very serious with a combination of no tillage and imperfectly drained soils
硝态氮的淋失虽然在免耕制下稍高一些，但在夏季作物上，一般不是氮损失的主要途径。 |
| 8. | Nutrients that are mobile in the soil profile must be supplied near to the time of maximum need in humid regions in order to prevent loss
在湿润地区，为防止养分淋失，应将移动性强的养分在接近最需要的时候施用。 |
| 9. | Factors such as soil texture , landscape , climate , irrigation , crop type , and nitrogen management influence intensity of no3 - loss through leaching
土壤质地、地貌、气候、灌溉、作物类型和氮素管理等因素影响到淋失的强度。 |
| 10. | It is apparent that a high degree of ammonia volatilization and / or nitrate leaching can occur in cropping systems susceptible to previously described conditions
很明显，高的氨挥发和(或)硝态氮的淋失会发生在符合上述条件的任何种植制度中。 |
