| 1. | Crop residues are left on the surface .
作物的残根留在地面。 |
| 2. | Incorporation of crop residues ; conventional tillage
把作物残体混入土壤的传统耕作制。 |
| 3. | 8 . 2 utilization of crop residues
农作物桔梗的利用 |
| 4. | Whether placement of nitrogen fertilizer below the layer of crop residue will reduce nitrogen immobilization is not clear
对于把氮肥施在植物残体覆盖层以下是否会减少氮的固定，这个问题目前尚不清楚。 |
| 5. | Experiments in kentucky tend to show the same degree of immobilization when nitrogen is placed on crop residue or when placed below the residue layer
但肯塔基的试验结果似乎表明：无论把氮肥施在植物残体上还是施在覆盖层下，氮的固定程度相同。 |
| 6. | Control methods include genetic resistance , proper crop rotation , tillage practices to bury crop residues that promote disease development , and fungicides
控制病害的方法包括：选抗病品种、合理轮作、把易发生病害的作物残体翻入土内、杀真菌剂的应用等。 |
| 7. | This made her no - tillage fields no different from the traditional ones . this resulted in undermining the role of crop residues in keeping moisture and raising soil fertility
免耕地很快便与传统耕作地毫无差异，极大地降低了留秸秆根茬保水保墒提高土壤肥力的作用。 |
| 8. | This technical support and training related to the utilization of crop residues is addressed in the " technology transfer " sub - component and the training plans for cow - calf farmers and feedlots
这些同农作物桔梗的利用相关的技术支持和培训在“技术转让”的次领域和母牛犊牛管理农民和饲养场的培训计划中得到解决。 |
| 9. | Not only could n ' t the quantity of soil organic matter and organic n be lifted up , but also did it lead , to soil erosion and output declining under nc - ti ! ! age system without crop residue adding
实行免耕制，关键是有机残体的返还。研究表明，一旦免耕与覆盖分离，则免耕即不能提高有机质和有机氮水平，导致土壤退化和减产。 |
| 10. | The environmental management considerations of the project include a pasture management , b reduction of air pollution by feeding , rather than burning , crop residues , c manure management plans for feedlots and d effluent management for processing plants
通过将农作物桔梗作为饲料而不是烧掉减少大气污染， c饲养场的粪便管理计划， |
