| 摘 要： | 分析总结了农业部保护性耕作示范效果(10个县)2003年的监测成果。试验表明，保护性耕作的抗旱、保墒、培肥土壤、增产、增收和防治沙尘暴等都初见成效。尤其在旱地的效果更佳。试验未发现保护性耕作比传统耕作的病虫害严重，但免耕的杂草量比传统耕作的要多，经过施用除草剂可以得到控制。在保护性耕作的实施过程中，需要农艺与农机有机结合，不断创新和完善适合不同类型区的保护性耕作技术模式。

| Abstract: | Ten key demonstration sites were set up in Northern China by the Ministry of Agriculture to test the comprehensive effects of conservation tillage under different natural and social situations. Preliminary results from one year data proved that conservation tillage can save water, control erosion, improve soil fertility; increase yield and net income. These effects are more clear in dry land areas. The diseases and pests in consevation tillage plots are no more than that from conventional tillage plots.Conservation tillage may have more weeds problem but it can be solved effectively by herbicide. It is necessary to continue the test to further confirm the results. [ |
