摘要:
为实现盐碱土条件下煤炭腐植酸在玉米上的合理利用，采用田间小区试验，分别设置空白对照（CK）、单施化肥（T1）、低量煤炭腐植酸（T2）、中量煤炭腐植酸（T3）、高量煤炭腐植酸（T4）、低化肥与低量腐植酸配施（T5）6个处理，比较分析了各处理对土壤盐碱性和玉米灌浆期干物质积累的影响。结果表明：煤炭腐植酸能够明显降低土壤pH和土壤EC，且降低幅度均随着腐植酸施用量的增多而增加。与CK处理相比，T4处理使土壤pH降低了1.83，使土壤EC降低了20%，T3、T5处理次之，T1、T2处理作用效果不明显。施用化肥、腐植酸、化肥与腐植酸配施均能提高玉米灌浆期干物质积累。相比之下，T3和T5处理玉米整株和籽粒的干物质量二者相当，却均显著高于其它处理（P＜0.05）。
Abstract:
In order to achieve reasonable utilization of coal humic acid in maize production under salinealkaline soil conditions,a field plot test was carried out by setting six treatments,including blank control (CK),chemical fertilizer for single application (T1),low amount of coal humic acid (T2),medium amount of coal humic acid (T3),high amount of coal humic acid (T4),and low fertilizers and low level of humic acid (T5).The effects of each treatment on soil salinity and maize dry matter accumulation during grouting period were compared and analyzed in the paper.The results showed that coal humic acid could decrease obviously soil pH and soil EC,and the decrease rate increased with the increase of humic acid application.Compared with CK treatment,T4 treatment reduced the soil pH by 1.83,reduced the soil EC by 20%,followed by T3 and T5,no significant effects in T1 and T2.Application of chemical fertilizer,humic acid and their group can improve maize dry matter accumulation during grouting period.By contrast,dry matter weight of whole plant and grain in T3 and T5 were almost unanimous,but were significantly higher than other treatments (P<0.05).
