不同菜地土壤中磷积累形态变化特征研究
Change Characteristics of Phosphorus Accumulated Form in Different Types of Vegetable Soil
摘要
Abstract
Long-term application of chemical fertilizer and livestock and poultry manure could lead to the accumulation of phosphorus in soil, and influence soil phosphorus bioavailability and mobility, which is related to the chemical forms of phosphorus in the soil. In order to study the relationship between phosphorus chemical forms in accumulation and soil properties, the author made different phosphorus accumulated soil by adding chemical fertilizer and pig manure to five soil types including red slime, quaternary red earth, muddy field, pale fluviogenic slime and oil yellow mud, phosphorus chemical form and release potential were analyzed by Hedley phosphorus form analysis method. The results showed that compared with CK, the accumulation of phosphorus had significant effect on the increasing range of H2O-P and NaHCO3-IP in all vegetable soil, the accumulation of phosphorus could improve the formation of HCl-P in neutral and limy soil, and it had little effect on the formation of NaOH-IP; in the allite soil, the accumulation of phosphorus was beneficial to the formation of NaOH-IP, but it had little effect on the formation of HCl-P. No matter it was chemical fertilizer or organic manure, the accumulation of phosphorus in soil was mainly inorganic, which had little effect on organic phosphorus. With the continuous accumulation of soil phosphorus, the effect on H2O-P and NaHCO3-IP was more obvious.关键词
