What are the detailed requirements for landscaping?
The quality of soil is directly related to the future growth of plants. It is necessary to analyze its physical and chemical properties, such as pH value, porosity, water permeability, water holding capacity, etc., and then take corresponding measures, such as disinfection, application of base fertilizer, exotic soil, etc. In particular, the excavation depth of soil, the quality of foreign soil, the maturity and application amount of base fertilizer and the flatness of terrain should meet the relevant requirements.

Treatment of fixed-point pay-off

Generally, it is required that the location is accurate and clearly marked. The planting hole is marked with the center point, and the planting groove is marked with the sideline. But under special circumstances, it needs to be handled flexibly. For example, when planting trees in the isolation belt, it is required to keep a distance of 2 meters from the lamppost when meeting it, so the setting-out must be handled flexibly and the spacing between trees should be adjusted appropriately. There is also the fixed point of street trees. Due to underground pipelines, fire hydrants, shops and other factors on both sides of the road, some appropriate adjustments are often needed.

Digging planting pits and planting troughs

The excavation of planting holes and planting grooves depends on the root system of seedlings, the diameter of soil balls and soil conditions, especially the planting holes with poor soil quality must be dug deep, and then base fertilizer and exotic soil should be applied to create a small environment conducive to plant growth.

Ensure the quality of seedlings

Strictly control the variety, plant type, crown width, height, trunk diameter, soil ball size and root development of seedlings, and select excellent seedlings that meet the design requirements, grow healthily, have no mechanical damage and no pests and diseases.

Seedling planting

Before planting seedlings, the roots and crowns of seedlings should be trimmed to remove the non-perishable packaging materials with soil balls; When planting trees with soil balls, the bottom of the planting hole should be leveled, and the bottom of the planting hole should be filled with soil into a cone for bare roots; When filling the soil, it should be compacted in layers, preferably with a hoe, leaving no gap; Pay attention to the direction of the surface.

Root water must be poured thoroughly within 24 hours after planting.

Fixed stay

Trees over 5 cm should be fixed with posts, and the fixtures should be kept neat.

Only in strict accordance with the construction technology, after the completion of each working procedure, can it be handed over to the next working procedure to continue the construction. Only by handing over the inspection step by step can the construction quality be guaranteed.
