| 3. | 2 . there were significantly different of nutrient balance among different land use type of hourshold
2 、农户不同土地利用方式间养分平衡存在差异。 |
| 4. | Organic fertilizer is the important link of maintaining and improving soil nutrient equilibrium and improving soil fertility
有机肥是维持和促进土壤养分平衡，培肥土壤的重要环节。 |
| 5. | The nutrient balance in different kind of crops and cropping systems , as well as the nutrient input of different farmers were similar pattern with quzhou county
不同作物和种植制度的养分平衡情况及不同农户的养分投入情况与曲周县的整体情况大体一致。 |
| 6. | The study also discovered that both the present fertilization system based on inorganic n and inorganic p and the present system of continuous cropping of corn had greats effect on balance of soil nutrients
研究还发现，现行的以无机氮磷肥为主的施肥制度和玉米连作种植制度对土壤养分平衡有很大影响。 |
| 7. | Efficient agricultural production demands a balanced nutrient approach between phosphorus , potassium , secondary and micronutrients , and nitrogen which plays the most significant role in the majority of production systems
高效的农业生产要求在多数生产体系中起重要作用的氮素与磷、钾、其它中微量营养元素之间取得养分平衡。 |
| 8. | Based on the analysis of data from hoursehold survey , literature and statistics in quzhou county of hebei province , the nutrient balance was analysed and evaluated under different scale and different crop systems
本文以农户调查数据、文献分析及统计分析相结合的方法，对河北省曲周县不同尺度和不同种植体系的养分平衡分析和评价。 |
| 9. | So the saline soil could be cultivated as farmland . finally the soil fertility was gradually increased with the chemical fertilizer inputing . ( 6 ) there were the evidence of nitrate accumulation in the groundwater pesticide and high weigh metals accumulation in the surface soil , with the more utilization of fertilzer and pesticide
由于地下水位是制约表层盐分含量的关键因素，地下水位的降低使表层土壤脱盐成为可能，而土壤表层盐分含量降低使盐碱地成为可垦地，开垦以后的土地投入增加和不同用地类型投入的差异促使养分平衡向养分积累方向发展，促使土壤养分大幅度上升和不同用地类型养分含量产生差异。 |
| 10. | In order to meet the need of modern and sustainable agricultural development , chemical fertilizer and organic fertilizer should be paid equal attention , chemical fertilizer should be applied coordinately , which is helpful to meet fertilizer requirement , regulate soil nutrient equilibrium and realize the combination of using soil with the maintenance of soil fertility to acquire high yield , high quality , reduce cost and increase benefit
根据现代农业和持续农业的要求，应强调化肥与有机肥并重和化肥合理配施，以满足供肥需求，调节土壤养分平衡，使用地养地相结合，达到高产、优质、节本增效的目的。 |
