摘要
在塔里木盆地干旱绿洲区开展棉花膜下滴灌田间试验,分析了灌水周期对土壤水盐分布的影响。结果表明,灌水周期为7d时,棉花主根区土壤水分状况良好,脱盐效果最佳,棉花铃数和籽棉产量最高。建议该地区选择灌水周期为7d的灌溉模式。
Field experiments under mulched drip irrigation were carried out in arid oasis region of the Tarim basin to analyze the impacts of irrigation frequency on soil water and salt distribution. Results showed that in the irrigation period of 7 d cotton taproot areas could remain high soil moisture and the best desalination, at the same time,the number of cotton boll and the yield of seed cotton were the highest. Irrigation frequency of 7 d is recommended in the area.
