A summary on applying new technique for potato planting in zero tillage rice field covered with rice straw during total growth period 稻田免耕稻草全程覆盖种植马铃薯新技术应用总结
Effects of different amounts of fertilizer applied on potato yield in zero tillage rice field covered with rice straw during total growth period 不同施肥量对稻田免耕稻草全程覆盖种植马铃薯产量的影响
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。
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。
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。
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。
