两年的盆栽试验及田间试验结果表明,磷素无论单施或与氮、钾配合施用,对豌豆的长势,籽粒产量和根腐病发病程度的减轻均有良好的影响,而钾素的影响不佳,氮素的影响居中。究其原因主要是由于供试土壤黄绵土全磷的贮备和速效磷的含量低,而钾素的供应丰富所致。 Two-year pot experiment and field experiment showed that the application of phosphorus alone or in combination with nitrogen and potassium had a good effect on the growth of pea, grain yield and alleviation of the incidence of root rot, while the effect of potassium Poor, the impact of nitrogen is the middle. The reason is mainly due to the reserves of total phosphorus in loessial soil and the content of available phosphorus in the soil are low, while the supply of potassium is abundant.
