摘　　要：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 activated phosphate fertilizer is prepared by using activating agents to treat the low- grade ground phosphate rock. The field tests of applying the activated phosphate fertilizer on different varieties of rice in different sites in Guangdong province are carried out. The results show that： compared with single superphosphate of the same weight, the yields of applying the activated phosphate fertilizer are increased by 6.4%-21.6%, the grains per panicle, filled grains, 1 000-grain weight and seed setting rate are also increased, the production of activated phosphate fertilizer is with the low-grade phosphate rock as raw material without acid, the utilization ratio of phosphorus is increased, with significant economic and environmental benefits.
