| 摘 要： | 通过田间试验对不同水肥条件下土壤NO3--N、速效磷、速效钾、盐分分布进行研究,结果表明：在滴灌施肥条件下,土壤剖面NO3--N分布主要集中在湿润体边缘,速效磷主要分布在0～30cm范围,速效钾主要分布在0～40cm范围;合理水肥比例可提高红枣对养分的吸收和减少养分在土壤中的积累且影响土壤盐分分布。试验结果为盐渍化土壤水肥一体化管理提供参考。

| Abstract: | Research is done on the distribution of nitrate nitrogen,available phosphorus and potassium in the soil under different fertilizer and irrigation conditions through field experiments.The results show that under drip irrigation and fertigation conditions,soil nitrate nitrogen contents are easily leached by irrigation water and distributed mainly outside the moist volume,available phosphorus is mainly distributed in the 0~30 cm soil profile and available potassium is mainly distributed in the 0~40 cm soil pro... |
