摘　　要：为考察单一磷源(磷酸一铵)、混合磷源(聚磷酸铵+磷酸一铵)的液体肥料中添加腐殖酸前后对棉花生长发育和磷肥利用率的影响,以不施磷肥为对照(CK),开展了田间小区试验。结果表明:施用混合磷源+腐殖酸液体肥料处理的打顶后棉花株高、盛铃前期叶片的叶绿素相对含量(SPAD值)较施用单一磷源液体肥料和CK处理的分别提高4.8%、6.5%和11.8%、9.1%;在生育后期,施用混合磷源+腐殖酸液体肥料处理的吐絮期干物质积累量、籽棉产量较施用单一磷源液体肥料和CK处理的分别提高7.4%、12.4%和25.3%、33.7%;施用混合磷源+腐殖酸液体肥料处理的磷肥利用率和农学利用率较施用单一磷源液体肥料的提高46.2%、77.1%。棉花生产中施用混合磷源+腐殖酸液体肥料在提高肥料利用率、增加棉花干物质积累量和籽棉产量等方面表现出优势。In order to investigate the effects of before and after adding humic acid to liquid fertilizers of single phosphorus source(monoammonium phosphate)and mixed phosphorus source(ammonium polyphosphate+monoammonium phosphate)on cotton growth and utilization rate of phosphorus fertilizer,a field plot experiment is conducted with no phosphorus fertilizer as a control(CK).The results show that the application of mixed phosphorus source and humic acid liquid fertilizer treatment increased the height of cotton plants after topping off and the relative chlorophyll content(SPAD value)of leaves before full boiling stage by 4.8%,6.5%and 11.8%,9.1%respectively,compared to the application of single phosphorus source liquid fertilizer and CK treatment.In the later stage of growth,the dry matter accumulation and seed cotton yield of the treatment with mixed phosphorus source and humic acid liquid fertilizer increased by 7.4%,12.4%and 25.3%,33.7%respectively,compared to the treatment with single phosphorus source liquid fertilizer and CK.The utilization efficiency and agronomic efficiency of phosphorus fertilizer treated with mixed phosphorus source and humic acid liquid fertilizer are 46.2%and 77.1%higher than those treated with single phosphorus source liquid fertilizer.The application of mixed phosphorus source and humic acid liquid fertilizer in cotton production has shown advantages in improving fertilizer utilization efficiency,increasing cotton dry matter accumulation,and seed cotton yield.
