2.苗木种植前的土壤处理技术措施

Technical measures for soil treatment of 2. seedlings before planting

土壤是苗木生存的根本，种植前对土壤的处理是提高苗木成活率的关键所在。

Soil is the root of the survival of the seedlings, and the treatment of soil before planting is the key to improve the survival rate of the seedlings.

首先，我们应确保苗木种植土层有足够的厚度，保证土质肥沃疏松，良好的透气性和排水性。

First of all, we should ensure that the soil layer of the seedling is enough to ensure the fertile and loose soil, good air permeability and drainage.

其次，我们要在种植或播种前对该地区的土壤性质进行化验分析，采取相应的消毒、施肥和客土等措施。园林植物生长所必需的最低种植土层厚度应符合，草本花卉土层厚度30㎝，草坪地被30cm，小灌木45cm，大灌木60cm，浅根性乔木90cm，深根性乔木150cm。

Secondly, we should be in before planting or sowing on soil properties in the area of analysis, take corresponding measures such as fertilization and soil disinfection. The minimum thickness of soil by planting garden plant growth should be consistent with the thickness of 30 cm, herbaceous flowers, lawn is 30cm, small shrub 45cm, large shrub 60cm, shallow rooted trees 90cm, deep rooted tree 150cm.
