存在问题: (1)偏重施氮肥,有机肥施用少。易造成枝条徒长,花芽分化不良,果品质量差,产量不稳定,且容易表现各种缺素症状。 (2)施肥方法不当,施入过深或过浅。有的果农沿用稀植大冠时期的老技术,肥料全部施到60厘米以下。也有的果农,不论什么肥料一律撒到树盘表面。个别果园还存在施肥部位离主干过近,伤根较多,以及施肥过于集中,造成烧根等现象。 (3)施肥比例和时期欠科学。尽管在施肥方面推广秋施基肥、科学配比、分次施入技术已有多年,但仍有不少果农在施肥上,习惯上坚持春天一次性施入法。往往难以充分发挥所施肥料的作用。 Problems: (1) emphasis on nitrogen fertilizer, organic fertilizer less. It is easy to cause twigs to be lengthened, poorly differentiated flower buds, poor fruit quality, unstable yield, and easy to show various symptoms of deficiency. (2) improper fertilization methods, applied too deep or too shallow. Some fruit growers continue to use the old technology of the period of rare plantation, fertilizer all applied to 60 cm below. Some farmers, no matter what fertilizer should be sprinkled on the surface of the tree. There are also some individual orchards fertilization site from the trunk too close, more root injury, and fertilization is too concentrated, resulting in burning roots and so on. (3) The proportion and period of fertilization owe science. Although the application of autumn-based fertilizer in the area of ​​fertilization, scientific matching and application of graded technologies for many years have been carried out for many years, many peasants still practice fertilizing on a one-time basis in spring. Often it is difficult to give full play to the role of fertilizers.
