摘  要：
为了进一步探究不同覆膜宽度对棉花土壤水分及地温的影响,试验对2种覆膜宽度下棉花各生育期0～25 cm处土壤温度、0～100 cm处土壤水分等指标进行观测。结果表明:超宽膜(2.05 m)较窄膜(1.4 m)效果显著;不同覆膜宽度情况下土壤温度日变化趋势相近,表层5 cm处土壤温度受大气温度的影响较大,随土层深度增加影响减弱并有一定的滞后效果;棉花生育后期5～25 cm处土壤平均温度超宽膜较窄膜高0.1～1.1℃。棉花各生育期25 cm土层以上,土壤含水率与土壤温度呈负相关,当土壤含水率低时土壤温度高,且超宽膜条件下相关性高于窄膜,超宽膜覆盖改善了土壤的水热条件,进而使作物生长发育加快;对北疆棉花种植而言,使用超宽膜覆盖较窄膜每公顷增产13.7%,增产效果显著;该研究成果可为北疆棉花种植生产提供一定的科学依据。

摘  要：
In order to further explore the influence of different covering film width on soil moisture and soil temperature of cotton,the soil temperature at 0 ～ 25 cm layer and the soil moisture at 0 ～ 100 cm layer were measured for the two growing widths of cotton. The results show that the effect of the super wide film( 2.05 m) treatment is more significant than that of the narrow( 1.4 m) film treatment; the trend of the diurnal variation of soil temperature under different film width is similar,the soil surface temperature at 5 cm layer is significantly affected by atmospheric temperature,and the effect is weakened and lagged with the increase of soil depth; at the later growth stage of cotton,the average soil temperature at 5 ～ 25 cm layer of the super wide film treatment is higher than that of the narrow treatment by 0.1 ～ 1.1 ℃; at the layer of under 25 cm,the soil moisture content is negatively correlated with soil temperature at different growth stages; when soil moisture content is low,the soil temperature is high,and the correlation under the super wide film treatment is higher than that of the narrow film treatment. The super wide membrane mulching improves the water and heat conditions of the soil,and accelerates the growth and development of crops. For the cotton planting in the North Xinjiang,the use of super wide film mulching has a yield increase of 13.7% per hectare. The research results can provide a scientific basis for cotton production in North Xinjiang.
