不同磺化腐殖酸磷肥提高冬小麦产量和磷素吸收利用的效应研究

The effect of sulfonated humus acid phosphate fertilizer on enhancing grain yield and phosphorus uptake and utilization in winter wheat

  • 摘要:
    目的 腐殖酸对磷肥增效的调控效应与其结构性密切相关。本文比较了不同磺化反应方法制备的腐殖酸磷肥对冬小麦磷素利用的影响,为制备调控磷肥专用的腐殖酸增效载体提供依据。
    方法 采用磷酸与氢氧化钾反应法制备普通磷肥 (P)、普通腐殖酸磷肥 (HAP),并采用加双氧水、硝酸等方法制备了四种磺化腐殖酸磷肥 (HA1P、HA2P、HA3P和HA4P)。用田间土柱栽培试验方法,在等磷量基础上,设置普通磷肥 (P)、普通腐殖酸磷肥 (HAP)、磺甲基化腐殖酸磷肥 (HA1P)、双氧水+磺甲基化腐殖酸磷肥 (HA2P)、硝酸+磺甲基化腐殖酸磷肥 (HA3P)、双氧水+硝酸+磺甲基化腐殖酸磷肥 (HA4P) 6个处理,同时设置不施磷肥对照 (CK) 处理和施用等量腐殖酸处理 (C-HA、C-HA1、C-HA2、C-HA3、C-HA4)。调查了小麦产量和产量构成及经济效益,分析了0—80 cm土壤有效磷含量。
    结果 1) 与CK相比,普通腐殖酸 (C-HA) 和磺化处理腐殖酸 (C-HA1、C-HA2、C-HA3、C-HA4) 对小麦籽粒产量无显著影响。与P处理比较,HAP、HA1P、HA2P、HA3P、HA4P处理的小麦籽粒产量分别提高了6.3%、17.8%、10.1%、17.5%、11.1%,4个腐殖酸磺化磷肥 (HA1P、HA2P、HA3P、HA4P) 处理均高于普通腐殖酸磷肥 (HAP) 处理。2)与HAP比较,磺化腐殖酸磷肥处理HA1P、HA2P、HA3P、HA4P分别提高小麦地上部磷吸收量12.3%、12.3%、9.2%、10.8%,其中HA1P和HA2P处理最高。3)与HAP比较,磺化腐殖酸磷肥处理HA1P、HA3P分别提高小麦磷肥农学效率23.6%和7.1%。4)与HAP比较,磺化腐殖酸磷肥处理HA1P、HA2P、HA4P可分别提高0—20 cm土层土壤速效磷含量17.5%、16.2%、17.2%。
    结论 磺化腐殖酸磷肥比普通腐殖酸磷肥可以更有效地提高土壤中磷肥的有效性,提高冬小麦对磷素的吸收利用,进而提高冬小麦籽粒产量。四种磺化工艺中,以磺甲基化处理的腐殖酸磷肥 (HA1P) 效果最优。

     

    Abstract:
    Objectives The regulation effect of humic acid on the synergistic effect of phosphate fertilizer is closely related to its chemical structure. In this paper, the effects of sulfonated humic acid phosphate fertilizers processed with different paths were compared, which would provide a basis for the preparation of high efficient humic acid phosphorous fertilizer.
    Methods A soil column cultivation method was used for the experiment on field condition and wheat was used as tested crop. Common phosphate fertilizer (P) and conventional humic acid phosphate fertilizer (HAP) were used as controls. Sulfonated fertilizers included sulfomethylated humic acid phosphate fertilizer (HA1P), hydrogen peroxide + sulfonate methylated humic acid phosphate fertilizer (HA2P), nitric acid + sulfomethylated humic acid phosphate fertilizer (HA3P) and hydrogen peroxide + nitric acid + sulfomethylated humic acid phosphate fertilizer (HA4P). We investigated the P content in wheat plant and grains, the yield and yield composition, economic benefits, and analyzed the available phosphorus content in 0−80 cm soil.
    Results 1) Compared with CK, all the C-HA, C-HA1, C-HA2, C-HA3, C-HA4 treatments did not show significant effect on wheat grain yield. Compared with P, the yield of wheat in HA1P, HA2P, HA3P, HA4P treatments were increased by 17.8%, 10.1%, 17.5% and 11.1%, and the yield in HAP was increased by 6.3%, lower than those in sulfonated HAPs. 2) Compared with HAP, the P uptakes of aboveground in HA1P, HA2P, HA3P and HA4P treatments were increased by 12.3%, 12.3%, 9.2%, 10.8%, respectively. 3) Compared with HAP, HA1P and HA3P treatments could increase the agronomic efficiency of phosphate fertilizer by 23.6% and 7.1%, respectively. 4) Compared with HAP, the available phosphorus contents in HA1P, HA2P and HA4P in 0–20 cm soil layer were increased by 17.5%, 16.2%, and 17.2%, respectively.
    Conclusions Sulfonated humic acid phosphate fertilizers perform better synergistic effects than common humic acid phosphate fertilizer in increasing the availability of phosphorous fertilizers in soil, so lead to better promotion effect in the absorption and utilization of phosphorus by winter wheat, and higher yield as a result. Among the four tested processes, the sulfomethylated humic acid phosphate fertilizer (HA1P) produces the best effect.
