一、坚持高标准整地整地是造林的一项基础性工作,也是提高造林成活率的一项关键技术。一般平原地区,栽植穴的规格以70cm见方为宜,为了便于浇水管理,以先挖沟后挖坑的形式最佳,即按行距挖70cm宽、20cm深的植树沟,然后再在沟内挖定植坑,深度达到50cm即可,这样既有利于苗木生长,又便于浇水,还能够有效地增加天然集水。滨海盐碱地区,应坚持大工程整地,抬高造林地面1～1.5m,宽度和长度视地块大小
First, insist on a high standard of soil preparation is a basic afforestation work, but also to improve the survival rate of afforestation is a key technology. In general plain areas, the specifications for planting holes should be 70 cm square. For the purpose of watering management, the best form of digging after digging ditches is dug the 70cm wide and 20cm deep planting ditch according to the row spacing, and then in the ditch Excavate the pit, the depth can reach 50cm, so that it is conducive to seedling growth, but also easy to water, but also can effectively increase the natural catchment. Coastal saline-alkali areas, should adhere to the large project site preparation, raising the afforestation 1 ~ 1.5m, width and length of the block size
