磷矿粉的增产效果磷矿粉是一种制造工艺简便,生产成本低廉的迟效性磷肥。推广使用磷矿粉,对解决当前速效性磷肥(过磷酸钙)不足,增加磷肥给源和磷肥品种,提高作物产量都具有重要意义。1973—1974年,我们在有关部门的领导和重视下,与原盘锦地区各县农林局、科研所、农场(公社)农科站和部分大、小队科研队,在
The effect of phosphate rock production phosphate rock powder is a manufacturing process is simple, low-cost production of the late-effective phosphate fertilizer. Promote the use of phosphate rock powder, to solve the current lack of available phosphate (superphosphate) deficiency, increase phosphate fertilizer source and phosphate fertilizer varieties, increase crop yield are of great significance. From 1973 to 1974, with the leadership and attention of relevant departments, we cooperated with the agro-forestry bureau, scientific research institutes, farms (communes) agricultural stations and some large and small scientific research teams of the original Panjin region
