新建果园时,幼苗的栽植深度,对栽植成活率及成活后的生长结实影响很大.实践中看出,幼苗栽植过浅,根系容易因覆土过浅而失水干燥;而栽植过深,则根际土壤的通气性不良,土壤温度较低,妨碍根系生长。这样栽的树,虽可成活,幼树的生长也受很大限制,有的发芽推迟, When planting new orchards, the planting depth of seedlings has a great influence on the planting survival rate and the growth and survival after surviving. In practice, it shows that the seedlings are planted too shallow and the root system is easily dehydrated and dried due to too shallow soil covering; The poor aeration of the rhizosphere soils and lower soil temperatures hinder root growth. Such planted trees, although they can survive, the growth of saplings are also subject to great limitations, and some delayed germination,
