摘要
通过大田试验，模拟研究了不同残膜量对土壤密度、水分运移及玉米产量的影响。结果表明，残留地膜使土壤密度降低2．02％～11．7％．土壤水分下渗速度减缓．土壤贮水量减少7．8～16．8mm，玉米产量降低4．8％～11．3％。
The effects of different residual plastic film quantities on soil density, soil moisture movement and maize yield were studied based on the field simulation experiments. The results showed that soil density decreased by 2. 02 % - 11. 7 %, soil water infiltration rate was reduced, the soil water storage decreased by 7. 6 - 6. 8 mm , and the maize yield were reduced by 4. 8 % - 11. 3 % using the residual plastic film.
