通过田间试验研究资源型功能磷肥对水稻产量、养分吸收及利用的影响。结果表明,与高浓度磷肥(HP)处理相比,两试验点3个资源型功能磷肥处理(LP1、LP2和LP3)平均增产8.3%和7.6%,磷肥吸收利用率平均提高29.4%和20.7%。资源型功能磷肥不仅能显著增产,还能显著促进磷的吸收及利用,应该大力推广施用。
Study on the Effect of Resource - functional Phosphates on Yield and Nutrient Absorption and Utilization of Rice by Field Experiment. The results showed that compared with high-concentration phosphate fertilizer (HP), three resource-type functional phosphate treatments (LP1, LP2 and LP3) increased 8.3% and 7.6% on average in the two experimental sites and the average utilization rate of phosphate fertilizer increased by 29.4% and 20.7% . Resource-based functional phosphate fertilizer can not only significantly increase production, but also significantly promote the absorption and utilization of phosphorus should be vigorously promote the application.
