近几年来,鈣鎂磷肥的使用,在国內外受到了广泛的注意,随着农业丰产对于肥料的需要,这种磷肥在江苏省很多地区都先后进行了生产試制与使用,为了进一步确定鈣鎂磷肥在全省范围內使用的肥效,我們在本省选用了几种主要的土壤类型,在田間与温室进行了肥效試驗,現将結果报告如下。試驗所用鈣鎂磷肥为本省錦屏磷肥厂所制,其化学組成列入表1。
In recent years, the use of calcium magnesium phosphate has received widespread attention both at home and abroad. With the demand of high-yielding agriculture for fertilizer, this phosphate fertilizer has been trial-produced and used in many areas in Jiangsu Province. In order to further determine the content of calcium and magnesium Fertilizer efficiencies for the use of phosphate fertilizers across the province We selected several major soil types in our province and conducted fertilizer tests in the fields and greenhouses. The results are reported below. Calcium magnesium phosphate used in the experiment for the province Jinping phosphate plant, the chemical composition listed in Table 1.
