磷矿粉是一种制造工艺简单,生产成本低廉的磷肥。推广施用磷矿粉肥,对合理利用磷矿资源,增加磷肥给源和磷肥品种,从而提高农作物产量,具有重要的现实意义。在农林部和燃化部的领导和重视下,在长沙“全国三磷会议”的推动下,本省组织有关地区、县农科所、农业局、农场、农技站和社、队农科站,于1972～1973年间,对国产磷矿粉进行了肥效多点试验和示范推广工作。并在此基础上,对磷矿粉的后效及有效施用技术进行了研究,取得了一定的成果。
Phosphate rock powder is a kind of phosphate fertilizer with simple manufacturing process and low production cost. Promote the use of phosphate fertilizer, the rational use of phosphate rock resources, increase phosphate fertilizer source and phosphate fertilizer varieties, thereby increasing crop yield, has important practical significance. Under the leadership and attention of the Ministry of Agriculture and Forestry and the Ministry of Combustion, under the impetus of the “National Tri-Phosphorus Conference” in Changsha, the province organized the agricultural science research institutes, agricultural bureau, farms, agricultural technology stations, , From 1972 to 1973, conducted a multi-point test of fertilizer efficiency and demonstration and promotion of domestic phosphate rock. And on this basis, the aftertreatment of phosphate rock powder and the effective application of technology has been studied and achieved some results.
