土壤是苹果生长的基础,不加管理的果园土壤紧实、通气不良、微生物活动能力低,土壤肥力差。据试验,土壤中氧的含量不低于10%,根才能正常生长。土壤中有害盐类的含量,也直接影响着苹果根系的生长,如碳酸钠、硫酸钠、氧化钠等。加强果园土壤管理,主要应从以下三个方面着手:一、果园清耕。 Soil is the basis of apple growth. Uncontrolled orchard soil compaction, poor aeration, low microbial activity, poor soil fertility. According to the test, the content of oxygen in the soil is not less than 10%, the root can grow normally. Soil harmful salts, but also directly affect the growth of apple root system, such as sodium carbonate, sodium sulfate, sodium oxide. To strengthen orchard soil management, mainly from the following three aspects: First, the orchard clearing.
