| 【目的】研究不同形态的聚磷酸铵作为种肥在石灰性土壤上对大豆、小麦苗期生长及养分累积的
影响。【方法】通过盆栽试验，以不施肥作对照，磷酸一铵（MAP）、不同形态聚磷酸铵（液体型简称 APPL，
固体型简称 APPS）作为种肥，探讨不同磷源对大豆、小麦养分累积的影响。【结果】液体聚磷酸铵（APPL）
处理明显促进大豆生长，其地上部干重较固体聚磷酸铵（APPS）处理显著增加 48.2%，固体聚磷酸铵（APPS）
处理则对小麦生长效果最好，其地上部干重较 APPL 处理增加 34.9%；APPL 处理大豆地上部磷累积量最大，显
著高出 APPS 处理 38.8%；不同形态磷肥条件下，APPS 处理对小麦的生物量以及对磷、钙、镁养分的吸收量最高，
APPL 处理次之，MAP 处理效果最差，APPS 处理地上部磷累积量较 APPL 处理高 18.7%，是 MAP 处理的 2.5 倍。【结
论】在本试验条件下，以 MAP 处理作对照，APPL 处理大豆肥效最佳，地上部干重是对照的 2 倍多；APPS 处理
小麦肥效最好，其地上部干重较对照显著增加 79.3%。 |

| 【Objective】The effects of different forms of ammonium polyphosphate as seed fertilizer on the growth
and nutrient accumulation of soybean and wheat seedlings in calcareous soil were studied.【Method】 Pot experiments were
conducted to investigate the effects of different phosphorus sources on nutrient accumulation of soybean and wheat by using
monoammonium phosphate (MAP) and different forms of ammonium polyphosphate (APPL for liquid and APPS for solid) as
seed fertilizers with no fertilization as control. 【Result】 APPL treatment significantly promoted the growth of soybean, and
the shoot dry weight was increased by 48.2% compared with that of APPS treatment, while APPS treatment was the best for
the growth effect of wheat and its shoot dry weight increased by 34.9% compared with APPL treatment. The accumulation of
phosphorus in soybean shoots treated with APPL was the highest, significantly higher than that of APPS treatment by 38.8%.
Under different forms of phosphorus fertilizer, the biomass of wheat and the uptake of phosphorus, calcium and magnesium
in APPS treatment were the highest, followed by APPL treatment, and the effect of MAP treatment was the worst. The accumulation of phosphorus in soybean shoots treated with APPS was 18.7% higher than that of APPL treatment, which was 2.5
times higher than that of MAP treatment. 【Conclusion】 Under the experimental conditions, taking MAP treatment as control
group, the fertilizer efficiency of APPL treatment was the best for soybean, and the shoot dry weight was two times higher than
that of control group. The fertilizer efficiency of APPS treatment was the best for wheat, and the shoot dry weight was increased
by 79.3% compared with that of MAP treatment . |
