| 1. | surface soil just below the residue cover, micronutrients generally are less often deficient than under conventional |
| 由于少耕和免耕减少了水土流失，同时把养分富集在植物残茬覆盖下的土壤表层，所以，与传统耕作制相比，少耕和免耕一般不易发生微量元素的缺乏。 |
|
|
| | |
| 2. | observations show that because the soil is less disturbed, zero tillage results in less weed populations than conventional |
| 表8的资料和一些大田观察资料表明，因土壤较少被扰动，免耕比传统耕作的农田杂草群体更少。 |
|
|
| | |
| 3. | Typically, magnesium levels in soils under no tillage do not change materially from those under conventional |
| 免耕和传统耕作制相比，土壤中镁的含量没有实质的变化。 |
|
|
| | |
| 4. | Incorporation of crop residues; conventional tillage. |
| 把作物残体混入土壤的传统耕作制。 |
|
|
| | |
| 5. | other respects, fertilization of crops grown under reduced tillage is comparable to fertilization under conventional |
| 在所有的其它方面，少耕下的作物施肥和传统耕作制下的均类似。 |
|
|
| | |
| 6. | "Conventional tillage controls weed growth by plowing and cultivating, But no-till farming selectively |
| 传统的耕作方法将通过耕地来减少杂草的生长,但免耕农业选择使用除草剂来消灭杂草,以保护作物。 |
|
|
| | |
| 7. | information is available, it can be stated that minor element deficiencies are never worse under no tillage |
| 虽然目前对这一问题没有详细研究资料，但是我们可以说，和传统耕作制相比，免耕制下的微量元素缺乏不会更严重。 |
|
|
| | |
| 8. | a more diversified crop rotation, and the use of minimum and/or no-tillage technologies in lieu of conventional |
| 用更加多样化的轮作代替秋耕闲地，以及使用最少和/或免耕法技术代替传统的土壤耕种。 |
