2.Calculate the difference: If you need to adjust the material price difference and labor and machinery costs, you can calculate it according to a specific formula.

It should be transplanted by large trees.

Large trees (DBH greater than 20-100cm), the soil mass is generally between meters, depending on the specific variety, the easy to survive can be relatively small, and the soil mass that can survive is slightly larger.

For extra-large trees (DBH of 100 cm or more), soil mass is OK in this way.

As for the general tree, if the DBH is within 10cm, the soil mass is basically 60-80cm, the DBH is 10-20cm, the soil mass is generally 80cm, and some can choose 1 meter soil mass.

The soil mass of shrubs is generally controlled within 40-60cm, and most of them are selected as 40cm soil mass.

Shrubs and trees are generally used as plants. Small trees can be classified as shrubs (e.g., tall red-leaved heather), and large shrubs can be set together as trees (e.g., cherry blossoms).

The set of quotas is also alive, and the leader makes the set higher, and for the kind of ambiguity, it is set into an arbor; The leader makes the set lower, and the ambiguous can be set into a shrub. However, the maintenance period must correspond to the sub-order of planting, and it cannot be said that you are planting trees, but you are maintaining shrubs.

Let's talk about ribbons. There are two kinds of ribbons, one is by meter and the other is by square. Whether it is by meters or by squares, it should be set according to the requirements of the list. If you calculate the quota by yourself, try to use the square to set, which is easier to calculate and more convenient.

What you are asking is the shrub in what case it is calculated by square meters, this depends on how big the shrub is, if it is a ribbon of small shrubs, flower beds and the like, you can use the square to set. How many plants are in a square meter, and then how much is each plant, which can be calculated as xx yuan m2.

Shrubs are calculated in the 2009 quota per plant or squared.

The pruning of seedlings in the garden is generally applied to the labor cost quota.

Because the quota does not specify the ownership of pruning, the labor cost quota is generally applied now.
