摘要

为了探究PPMn型水溶肥混合棉粕腐植酸肥施用对棉田土壤和棉花产量的影响，通过红外光谱和扫描电镜分析两种新型水溶肥的官能团特征和外观特征，并利用田间小区试验研究了两种新型水溶肥对棉田土壤物理性质及团聚体、棉花产量和肥料利用率的影响。结果表明：施用棉粕腐植酸肥（H）、PPMn型水溶肥（P）和两种新型水溶肥混合（HP）对改善土壤物化结构和提升棉花产量均优于常规水溶肥（S）和不施肥（CK），其中HP处理效果最好。HP处理使土壤容重降低8.15%，土壤孔隙度增加7.49%，有效降低了<0.25 mm土壤团聚体所占比例，显著提升氮磷钾的农学利用效率，棉花产量相对于其他处理增加7.5%~41.0%。

Abstract

In order to explore the effects of PPMn type water soluble fertilizer mixed with humic acid of cottonseed meal fertilizer on soil properties and cotton yield

the functional and appearance characteristics of two novel water soluble fertilizers were studied by infrared spectroscopy and scanning electron microscopy analysis. The field experiments were also conducted to study soil physical properties

cotton yields and fertilizer use efficiency. The results showed that application of humic acid fertilizer of cottonseed meal (H)

PPMn type water soluble fertilizer (P) and two new types of water soluble fertilizer (HP) had the better effects on improving soil physicochemical structure and enhance the cotton yield than the conventional water soluble fertilizer (S) and no fertilizer (CK)

and HP gave the best. Under HP

soil bulk density was decreased by 8.15%

soil porosity was increased by 7.49%

the proportion of <0.25 mm soil aggregate was reduced effectively

the agronomic efficiency of nitrogen phosphorus and potassium was improved significantly

and the cotton yield was increased by 7.5%~41.0% compared with other treatments.
