中文摘要:
      为研究非生育期北疆膜下滴灌棉田在冻融过程中的土壤水盐运移规律,在石河子121团试验地开展了常规水分、盐分和温度监测试验。研究结果表明:气温对土壤温度的影响很大,随着土层深度的增加,各土层温度逐渐减小,气温对各土层的影响也逐渐变小。冻结前期,各层土壤水分随深度的增加而增加,水分主要集中在40~100 cm土层,盐分主要分布在80~100 cm土层。冻结期,水分波动较盐分剧烈,盐分大部分都集中在100 cm层。融解期,由于多次的冻融循环作用,各土层的水分含量变化比较大,而盐分在10~80 cm层变化不大,80~100 cm层盐分累积比较大。经过一个冬季,盐分主要分布在80~100 cm土层。
英文摘要:
      In order to study the soil water and salt movement rule of cotton field of drip irrigation under mulch in non-growth period in the process of freezing and thawing in northern Xinjiang,the paper carried out monitoring test about water, salt and temperature in Shihezi.The results showed that air temperature has a great influence on soil temperature.With the increase of soil depth,the temperature each soil layer gradually decreases.The impact of temperature on each soil layer gradually becomes smaller.In the early stage of freezing, the soil moisture each layer increases with the increase of depth,water is mainly concentrated in 40 ~ 100 cm soil layer,salt mainly distributes in 80 to 100 cm soil layer . In the stage of freezing,the change of water is bigger than that of salt,salt are mostly concentrated in 100 cm layer.In melting period,due to the influence of multiple freeze-thaw, the change of soil moisture content is relatively large, while the salt of 10 ~ 80cm layer changes little. The salt of 80 to 100cm layer accumulates relatively large.Through a winter,salt is mainly distributed in soil layer of 80 to 100 cm.
