1.整地和作畦:整地就是栽植前对土壤进行翻耕、耙平、去杂等整理工作,可有效地改变土壤的物理结构,改善土壤的通气透水条件,有利于土壤微生物活动,加快有机质分解转化,还可防止病虫害。整地一般在秋季进行,根据花卉的种类和土壤的不同,翻耕深度也不同,一二年生草花生长期短,根系浅,20—30厘米即可;宿根和球根花卉需30—40厘米;木本植物多以穴植为主,乔木宜深栽,灌木宜浅栽,绿篱宜沟栽,栽植穴深度从40—100厘米不等。作畦方式依地区、地势、栽培目的和花卉种类习性而定。
1. Soil preparation and crop preparation: Soil preparation is the tilling, raking and soil removal before planting, which can effectively change the physical structure of the soil and improve the aeration and permeation conditions of the soil, which is beneficial to soil microbial activities and the acceleration of organic matter Decomposition and transformation, but also to prevent pests and diseases. According to the different types of flowers and soil, the depth of tillage is also different. The perennial grass has a short growth period of 20-30 cm. The roots and bulbous flowers need 30-40 cm. Woody Plant to plant more holes, trees should be planted, should shallow shrubs, green hedge should ditch planting, planting depths ranging from 40-100 cm. The mode of operation depends on the region, topography, cultivation purposes and the habit of flowers.
