At present, most nurseries have a common problem, that is, they are planted too closely. Seedlings are densely planted, with small growth and slow growth; Poor light and permeability, weak tree vigor, and increased diseases and pests; Inconvenient for mechanized management; It is not suitable to cultivate the original crown seedlings and full crown seedlings currently advocated; The cultivated finished seedlings do not meet the needs of the current market. 浅栽。无论播种育苗，还是移栽苗木，都普遍种得太深，尤其是当前使用机械种植，更是如此。 Shallow planting. Whether sowing seedlings or transplanting seedlings, they are generally planted too deep, especially the current use of mechanical planting. 根系的生长，需要呼吸和一定的地温，要选择通透性好的土壤种植。根系埋藏深了，进行无氧呼吸，地温也低，影响新根系的形成和生长，老根系还容易腐朽、生病。 Root growth requires respiration and a certain ground temperature, and the soil with good permeability should be selected for planting. The root system is deeply buried, carries out anaerobic respiration, and the ground temperature is also low, which affects the formation and growth of new root system, and the old root system is also prone to decay and disease |
