近几年来,果园施用氮肥越来越多由于长期单一施氮肥,使土壤中的氮磷比例失调,土壤板结,理化性质被破坏,氮肥增产效果一直下降,造成适龄果树不能结果,缩短盛果期,大小年严重,品质差。因此在果园适量施用磷肥是很有必要的。一、磷肥对果树营养的作用磷肥是果树生长发育不可缺少的重要营养元素之 In recent years, more and more application of nitrogen fertilizer in orchards due to the long-term single application of nitrogen fertilizer, so that the proportion of nitrogen and phosphorus in the soil disorders, soil compaction, physical and chemical properties are destroyed, the effect of nitrogen fertilizer production has been declining, resulting in fruit age- The size of the year, poor quality. Therefore, proper application of phosphate fertilizer in the orchard is necessary. First, the role of phosphate fertilizer on the nutrition of fruit trees Phosphate fertilizer is an essential nutrient for growth and development of fruit trees
