| 1. | Effect of wetting and drying cycle of soil on consumption character of water by maize 土壤干湿交替对玉米耗水特性及水分利用的影响 |
| 2. | The fate of nitrogen forms of nitrogen fertilizers under alternate leaching and drying conditions 间歇淋洗干湿交替条件下氮肥的氮行为研究 |
| 3. | Effect of dry - wet alternate irrigation on rice quality and activities of some enzymes in grains during the filling 结实期干湿交替灌溉对稻米品质及籽粒中一些酶活性的影响 |
| 4. | In the area , the holocene climate alternately changed from cold to warm and from dry to wet and is mainly cool - dry 得出此地区全新世气候以冷暖、干湿交替出现,主要以温凉干旱为主。 |
| 5. | Laterite a hard crust that may form on the surface of the soil in tropical regions with alternating wet and dry seasons 红土:在热带地区,土壤表面由于干湿交替而行成的具有坚硬外壳的一种土壤。 |
| 6. | Patent claims of decreased dependence of nitrogen release rate on soil moisture , and soil variations from wet to dry are promising 这一专利声称该包膜可以减少土壤湿度及土壤干湿交替变化对氮素释放的影响,是很有价值的。 |
| 7. | With temperature increasing , potassium fixation capacity became stronger , and the effects varied among four kinds of soils . 3 提高温度,增强干湿交替的剧烈程度,显著地增加了土壤对钾的固定量,降低了所施肥料钾的有效性。 |
| 8. | Under the same soil moisture suction , water holding quantity in soils from high to low in turn was lou soil , hei - lu soil , loessial soil and aeolian - sandy soil 土壤水分动态变化过程(干湿交替次数)和变化强度(温度变化)对黄土高原地区四种土壤钾的有效性有较大影响。 |
| 9. | The first time of drying and wetting cycle gave the most influence to total quantity of fixed potassium , and with cycles increasing , it ' s influence became weaker 随着干湿交替次数增加,土壤对钾的固定量增大,且增加幅度逐渐趋于稳定。干湿交替次数与土壤速效钾含量间具有y = a + blogx函数关系。 |
| 10. | In the third chapter , the ratio of soil evaporation to crop transpiration under different furrow irrigation ways adopted in summer maize field was analyzed by using the measured data in lysimeters 与固定隔沟灌相比,交替隔沟灌土沟的干湿交替循环不会使根区部分土壤出现长期极度干燥的情况,因此对作物根系的生长和吸收比较有利。 |
