磷是农作物生长发育中不可缺少的营养元素,为植物营养的“三要素”之一,也是农作物组成中重要成分之一。“肥料是植物的粮食”。为了充分发挥磷肥对农作物的增产作用,把磷肥的使用建立在更科学更可靠的基础上。十多年来,我省着重在黄壤地区,进行了多次磷肥肥效及施用技术试验研究。现就磷矿粉肥、普钙、钙镁磷肥的试验研究结果及调查资料摘要汇总如下。
Phosphorus is an indispensable nutrient element in the growth and development of crops and is one of the “three elements” of plant nutrition. It is also one of the important components of crop composition. “Fertilizer is plant food.” In order to give full play to the role of phosphate fertilizer in crop production, the use of phosphate fertilizer is based on a more scientific and reliable basis. For more than a decade, our province has focused on the yellow soil area, carried out a number of fertilizer application efficiency and application of experimental research. Now on the phosphate rock fertilizer, calcium, magnesium phosphate fertilizer test results and summary of survey data summarized below.
