磷肥施用效果取决于一系列因素.但这一问题最终归结为,以多少用量和以何种形式来保证作物在个体发育的全部生育期中某些阶段的需要,从而使磷素不致成为在某种县体栽培条件下限制产量的因素.目前可以根据已有的磷素农业化学的经验和知识,在不显著提高物质技术费用前提下,拟定出增加磷肥施用效果的实际途径. The effect of phosphate application depends on a number of factors, but the question ultimately comes down to how much and in what form the crop will be needed at some stage of its full development so that it does not become At present, according to the existing experience and knowledge of phosphorus agrochemical, a practical way to increase the application effect of phosphate fertilizer can be worked out without significantly increasing the material and technical costs.
