| 7. | However , long term issues of zero tillage need to be explored to determine whether future problems or benefits may arise for this technology
但还需要研究免耕的长期影响，以确定这项技术将来是有利还是有害。 |
| 8. | 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。 |
| 9. | 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。 |
| 10. | Although zero tillage technology presents a potentially dramatic breakthrough for planting wheat in rice - wheat system , there are two issues meriting attention : danger of increasing population of stemborers for the following rice crop and the application of fertilizer , particularly n fertilizers
虽然免耕技术为稻麦制中播种小麦提供了潜力巨大的技术突破，但有二个问题值得注意：后茬水稻螟虫群体增多的危险和施肥，尤其是施氮肥的问题。 |
