different soil texture,different postemergences,from horizontal direction,from vertical direction and the relationship between the total salt content and cotton yield to analyse the salt transfer law for cotton field in Mosuowan reclamation area at the condition of different length of irrigation and different water quality.
为分析莫索湾垦区不同滴灌年限及不同水质灌溉棉田膜下滴灌盐分的运移规律,从不同土壤质地、不同生育时期、水平方向不同土层、垂直方向不同土层、总盐含量与产量间关系等5个方面对膜下滴灌盐分的运移进行了分析比对,初步得出:黏土中的盐分积累最重,壤土中次之,砂土积累最少;随着生育时期的推后,各土层含盐量都有不同程度的加大;水平方向露地行中央土层盐分积累最多,滴头处盐分积累最少;垂直方向盐分的积累在0—60cm土层逐渐增加,60—100cm土层盐分积累受膜下滴灌影响较小;总盐含量越高产量下降越严重;总体来说,井水灌处理要比河水灌各处理积盐多。
We analyzed the charateristics of soil salt distribution under different distance of irrigation emitter,24 hours after irrigation.
以塔里木河下游35团8连绿洲-荒漠交界处滴灌条件下的新生林地为研究对象,对滴灌结束24 h后不同滴头间距下的土壤盐分分布特征进行了分析,结果显示①水平方向上,在3 m滴头间距下出现盐峰是在75 cm点处的土壤剖面,这一剖面与60 cm点处的土壤剖面盐分在0。
