不同改良剂对河套灌区盐渍化土壤性状和葵花生长特性的影响

Shuitu Baochi Xuebao, 2019
为了评价不同改良剂对盐渍化土壤的改良效果，以葵花为研究对象，采用大田裂区试验方法，设置生物炭（DC，22.5 t/hm2）、脱硫石膏（DS，37.5 t/hm2）、脱硫石膏加有机肥（DSF，各37.5 t/hm2）、对照（DCK）4种处理。结果表明：施加改良剂均降低了土壤容重，增加了土壤孔隙度，生物炭效果最明显，在耕层（0-20 cm）收获后较播种前土壤容重降低6.11%，是DCK的4倍，孔隙度增加12.89%，是DCK的5倍；脱硫石膏降低土壤pH和电导率效果最优，最大降幅分别为10.09%和28.51%

不同水盐处理对苜蓿耗水、品质及产量的影响

Shuitu Baochi Xuebao, 2019
为探索河套灌区不同盐分土壤苜蓿生长的适宜水分展开盆栽试验，设置3个水分水平、3个盐分水平和1个对照处理CK，监测不同水盐处理苜蓿现蕾期至初花期土壤贮水变化量、品质及产量。结果表明：（1）相同盐分条件下，植株株高、地上生物量、地下生物量、耗水量及干草产量随灌水量的增加而增大，但苜蓿的增产效应明显降低；相同水分条件下，随盐分增加，苜蓿耗水量及地下生物量整体呈现先增大后减小的变化趋势。土壤含盐量超过3 g/kg，土壤中剩余水分显著增加，且随灌水量增加逐渐增加。（2）土壤含盐量1~3 g/kg ...

水氮调控对休耕期土壤养分迁移及翌年土壤肥力的影响

Shuitu Baochi Xuebao, 2019
为研究河套灌区盐碱农田不同施氮量在冻融作用后对翌年春播前土壤肥力的影响效应，结合翌年土壤肥力状况确定当地适宜的施氮量。采用田间试验的方法，共设置4个施氮水平（高氮N3：325 kg/hm2；中氮N2：225 kg/hm2；低氮N1：125 kg/hm2；不施氮N0）研究冻融期内水盐时空分布、全氮、碱解氮以及有机质含量的变化规律，并采用主成分分析法对翌年春播前土壤肥力进行综合评价。结果表明：（1）秋浇后，土壤含水率显著高于秋浇前，表层土壤含水率增加，开始冻结时，水分向表层积聚 ...
