    摘要:

    為探索秸稈覆蓋模式及表土耕作方式對東北黑土根區(qū)土壤環(huán)境調(diào)控效應(yīng),,設(shè)置淺松覆蓋(STS),、免耕覆蓋(NTR),、淺松覆蓋+壓實(SCTS),、免耕覆蓋+壓實(NCTR)及翻耕秸稈不還田(對照TC)5個處理,,分析其對黑土區(qū)土壤水、熱,、養(yǎng)分及物理特性時空動態(tài)變化的影響,。結(jié)果表明:相對于傳統(tǒng)耕作,秸稈覆蓋與土壤壓實結(jié)合可改善土壤物理結(jié)構(gòu),,春播期,、秋收期0~50cm土層容重分別降低1.32%~4.06%、0.81%~1.64%,,0~30cm土層有機質(zhì)與速效養(yǎng)分含量分別提高4.89%~20.74%,、1.94%~40.37%與7.18%~30.26%、1.22%~28.09%,,0~70cm土層生長期墑情增加6.83%~13.84%,,調(diào)控苗期0~10cm土層溫度日溫差減小0.5~2.8℃,且對表層各因素影響高于底層,。秸稈覆蓋模式可降低機械壓實所引起的負(fù)效應(yīng),,從高效可持續(xù)方面綜合分析本試驗條件下淺松壓實覆蓋(SCTS)在改善根區(qū)土壤環(huán)境方面具有一定優(yōu)勢,研究成果可為東北黑土區(qū)覆蓋耕作措施實施提供參考依據(jù),。

    Abstract:

    In order to study the influence of different straw mulching modes and surface tillage adjustment measures on environmental regulation of root zone of the northeast black soil, field experiments were conducted under five tillage practices of surface tillage with straw mulching (STS), notillage with straw mulching (NTR),,surface tillage with straw mulching and compaction (SCTS), notillage with straw mulching and compaction (NCTR) and conventional tillage (contrast TC) for analyzing time and space dynamic change of soil moisture, heat, nutrient and physical properties by straw mode and surface tillage measures. The results showed that: straw mulching with surface tillage could improve soil physical structure on seeding stage and harvest stage, the soil bulk density of 0~50cm soil layer was reduced from 1.32% to 4.06% and 0.81% to 1.64%,the soil organic matter and available nutrients of 0~30cm soil layer were increased from 4.89% to 20.74%,1.94% to 40.37%,7.18% to 30.26% and 1.22% to 28.09%,the soil moisture of 0~70cm soil layer was increased from 6.83% to 1384%,,the daily soil temperature difference at seeding stage of 0~10cm soil layer was reduced from 0.5℃ to 2.8℃ than that of comparison TC, so the effect of surface soil layer was higher than that of the bottom layer. Under the experimental condition, SCTS has advantages on regulation soil environment of root zone for high efficient and sustainable comprehensive evaluation. Research results provide reference basis for promoting implementation of covering cultivation measures on the northeast black earth area.
