| 1. | Incorporation of crop residues ; conventional tillage 把作物残体混入土壤的传统耕作制。 |
| 2. | Typically , magnesium levels in soils under no tillage do not change materially from those under conventional tillage 免耕和传统耕作制相比,土壤中镁的含量没有实质的变化。 |
| 3. | In all other respects , fertilization of crops grown under reduced tillage is comparable to fertilization under conventional tillage 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。 |
| 4. | The result showed that the photosynthesis , stomata conductance and wue of no - tillage practices were higher than conventional tillage 结果表明,免耕措施下玉米的光合速率、气孔导度、水分利用效率均高于传统翻耕,气孔导度的日变化与光合速率显著相关。 |
| 5. | Data in table 8 and numerous field observations show that because the soil is less disturbed , zero tillage results in less weed populations than conventional tillage 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。 |
| 6. | While no detailed information is available , it can be stated that minor element deficiencies are never worse under no tillage compared to conventional 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。 |
| 7. | Because no tillage and minimum tillage reduce erosion and concentrate nutrients in the surface soil just below the residue cover , micronutrients generally are less often deficient than under conventional tillage 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。 |
| 8. | When this was done with the proper equipment , results from six sites in 1986 - 87 showed an average wheat yield of 3677 kg / ha with zero tillage against 2598 kg / ha with conventional tillage ; higher wheat due to earlier planting of wheat by 24 days 1986 ~ 87年6个点的结果表明,使用合适的机具免耕,平均小麦产量3677公斤/公顷,传统耕作只有2598公斤/公顷;高产来自早播小麦24天。 |
| 9. | According to the filed experiments in ansai , shaanxi , this article referred to the influence of conventional tillage , no - tillage , fertilizer and organic fertilizer on photosynthesis and stomata conductance of maize in hilly and gully arid region of loess plateau 摘要依据在陕西安塞进行的田间试验,研究了黄土丘陵旱农区传统翻耕和免耕及化肥和有机肥对玉米光合速率和气孔导度的影响。 |
