针对目前淮北石灰性土壤长期施用磷肥,土壤速效磷有逐年上升趋势,磷肥的增产效果不如前几年显著。通过小区试验,研究用沸石交换体代替磷肥对小麦的有效施用技术,结果表明:中等肥力砂姜黑土小麦亩施50kgNH4-沸石配合一定量的氮肥,增产效果显著,小麦产量为245.3kg/亩,比N12P4处理增产小麦23.skg,增产10.6%;比当地农民习惯施肥(N12P6)的肥料总投入每亩减少13.00元。用NH4-沸石交换体短期或部分代替磷肥使用,具有广阔的应用前景。 According to the long-term application of phosphate fertilizer in calcareous soil of Huaibei City, the available phosphorus content of soils has been increasing year by year. The stimulation effect of phosphate fertilizer is not as significant as that in previous years. Through the plot test, the effective application technology of wheat with zeolite exchange body instead of phosphate fertilizer was studied. The results showed that 50kgNH4-zeolite with medium fertility Shajiang black soil wheat with a certain amount of nitrogen fertilizer had a remarkable yield increasing effect. The yield of wheat was 245.3kg / mu , Yielding wheat 23 more than N12P4. skg, an increase of 10.6%; than the local farmers accustomed to fertilization (N12P6) of the total input of fertilizer reduced by 13.00 yuan per mu. With NH4-zeolite exchange body to replace phosphate fertilizer in short or partial use, it has broad application prospects.
