采用活化剂对低品位磷矿粉进行活化处理制取的新型高效活化磷肥,应用于不同品种水稻的大田试验表明:活化磷肥较等质量过磷酸钙的产量提高6.4%～21.6%,每穗总粒数、实粒数、千粒质量、结实率均有不同程度的增加。活化磷肥的生产不耗酸,可用低品位磷矿石,磷利用率提高,有明显的经济和环境效益。 The new high-efficiency activated phosphate fertilizer prepared by activation of low-grade phosphate rock with activator has been applied to field experiments of different varieties of rice. The results show that the yield of activated phosphate fertilizer is 6.4% ~ 21.6% higher than that of equivalent quality superphosphate, The number of grains, number of grains, grain weight and seed setting rate all increased in different degrees. Activated phosphate fertilizer production acid, available low-grade phosphate rock, phosphorus utilization increased, with significant economic and environmental benefits.
