中文摘要	为了研究不同覆膜年限棉田残膜对棉花及棉田土壤的影响,在典型绿洲区长期膜下滴灌棉田开展了不同残膜量的田间试验。选取自然条件下覆膜年限分别为7 a、9 a、11 a、13 a、15 a、17 a和21 a共6个不同残膜量棉田,标记为A、B、C、D、E和F处理,监测棉花出苗率、株高、茎粗、叶面积以及棉田土壤水盐分布和养分含量变化。结果表明:不同残膜量处理对长期覆膜棉田土壤水盐分布、养分含量和棉花生长均产生显著影响。残膜降低土壤水盐分布的均匀性,随残膜量增加土壤浅层含水率高于深层含水率,阻碍了土壤水分下渗;土壤盐分随水分迁移,高残膜处理土壤脱盐效果变差且出现盐分富集;残膜引起土壤养分退化,土壤铵态氮、硝态氮和有效磷含量降低,高残膜量F处理最多分别下降35.12%、17.30%和43.26%;棉花出苗率、株高、茎粗和叶面积等指标随残膜量增加而减小,高残膜量下最多分别降低9.00%、18.38%、21.77%和38.65%。以上分析表明,高残膜量对棉田土壤环境和棉花生长影响显著,研究结果可为绿洲区长期膜下滴灌棉田的绿色可持续发展提供理论依据和技术参考。
英文摘要	In order to study the effect of residual film in cotton fields with different film mulching years on cotton growth and soil,field experiments with different residual film amounts were carried out in a typical oasis area under long - term drip irrigated cotton fields. We selected 6 cotton fields that mulched 7 a,9 a,11 a,13 a,15 a, 17 a and 21 a under natural conditions,respectively,and marked them as A,B,C,D,E and F treatment, then monitored the cotton seedling emergence rate,plant height,stem diameter,leaf area,and changes in the cotton field soil water and salt distribution and nutrient content. The results showed that treatments with different amounts of residual film had significant effects on the distribution of soil water and salt,nutrient content and cotton growth in long - term film - mulched cotton fields. Residual film reduced the uniformity of soil water and salt distribution. As the amount of residual film increased,the water content of shallow soil was higher than that of deep soil,which hindered soil water infiltration. Soil desalination became worse in high residual film treatment due to soil salt migrating with water,so salt enrichment occurred. Residual film caused soil nutrient degradation. Soil ammonium nitrogen,nitrate nitrogen and available phosphorus contents decreased. In high residual film F treatment,they reduced 35.12%,17.30% and 43.26%,respectively. Cotton seedling emergence rate and plant height,stem thickness and leaf area decreased with the increase of residual film amount. Under high residual film amount,they decreased by 9.00%,18.38%,21.77% and 38.65%,respectively. The above analysis shows that the high residual film content has a significant impact on the soil environment of cotton fields and cotton growth. The research results can provide a theoretical basis and technical reference for the green and sustainable development of long - term drip irrigation cotton fields in oasis areas.
