摘  要:
为研究地膜再利用对向日葵田土壤过氧化氢酶活性的影响,进行了旧膜、新膜及露地栽培向日葵对比试验。结果表明,地膜再利用可提高土壤过氧化氢酶的活性。在0~40cm土层,旧膜的土壤过氧化氢酶活性较露地显著增加4.2%,较新膜增加2.6%。土壤过氧化氢酶活性随生育期变化而不同,呈平稳-下降-上升的变化趋势。旧膜覆盖可以维持耕作层(0~20cm)过氧化氢酶活性的较高水平及其稳定性,而下层呈快速下降的趋势,但各层土壤过氧化氢酶活性均表现为:旧膜>新膜>露地。可见,地膜覆盖尤其是地膜再利用覆盖由于改善了农田生态微环境,从而提高了土壤微生物活动和土壤过氧化氢酶活性。

摘  要:
Aiming at reducing agricultural pollution caused by plastic film,the effects of re-used plastic film mulching on soi1 catalase activity were studied through comparing with the plastic film and open field in Hetao region. The results showed: Soil catalase activity of re-used film mulching increased at different degree. Compared with bare field and new film mulching,soil catalase activity in 0-40 cm of re-used film were higher significantly 4. 2% and 2. 6% respectively. Growth stage changes of soil invertase catalase activity are different. Soi1 catalase activity was fluctuating decline effecting by irrigation,and with a minimum in squaring. Vertical changes of the soil catalase activity are reduced with increasing soil depth,but more stable activity in plough layer( 0-20cm). So the findings indicated re-used film could also enhance soil catalase activity though improved farmland ecological microenvironment.
