| 摘 要： | 通过黑土区田间长期定位试验,研究了秸秆覆盖度对太阳反射和土壤含水量的影响,进而探讨了其对土壤温度的调控作用。在作物出苗前,秸秆覆盖度免耕(覆盖度70%)>少耕(覆盖度10%)>旋松(覆盖度0%)。研究结果表明:免耕、少耕和旋松的累计反射强度依次递减,反射辐射强度越大土壤温度越低;免耕具有较高的质量含水量,质量含水量均与地温存在显著的负相关关系。

| Abstract: | The effects of global radiation and soil moisture on soil temperature were discussed by a long - term field experiment in black soil. During spring,the cover rates of three treatments were different,no tillage (cover rate 70% ) > reduced tillage (cover rate 10% ) > rotary tillage (cover rate 0% ). The results showed that the cumulative reflecting radiation was no tillage > reduced tillage > rotary tillage before emergence of seeding,and soil temperature decreased with the cumulative reflecting radiation inc... |
