How to determine the diameter of soil ball?

Question 1: How to calculate the diameter and height of soil balls of green seedlings? 5. Generally, soil balls are related to DBH of trees, and the size of soil balls is about 8 times that of DBH. In order to ensure the survival rate of large seedlings, the high seedling soil ball is about 10 times.

Trees are 6-8 times the diameter of the ground, and the thickness is 2/3 of the diameter of the soil ball. The smaller the diameter of the ground, the larger the value, and the smaller the value. For example, a tree with a diameter of 20 cm can be required to be dug to a diameter of 80 and a thickness of 60. 20cm trees, 1㎡ above, of course, 1㎡ is the best, and generally trees will not die.

Question 2: How to determine the specifications of arbor soil balls is usually used to calculate the project cost. According to the tree DBH 8 compensation, ground diameter 7 compensation, average diameter 1/3 calculation. (This is stipulated by the quota)

Of course, the actual diameter of soil ball depends on the survival rate of trees. The diameter of tree soil balls with high survival rate can be smaller, and the diameter of tree soil balls with low survival rate can be larger.

As a construction unit, the larger the diameter of the soil ball, the higher the digging and transportation cost. But now Party A generally requires that the seedling maintenance period is two years, so the larger the diameter of the soil ball, the higher the survival rate and the lower the cost of keeping alive, and vice versa. In general, the diameter of soil ball should be determined according to experience. If you buy Qiao Qiao mu at the site price, the price will remain unchanged, and the diameter of Miao Qiang's soil ball is required to be as large as possible, so that the survival rate is high and the planting soil is saved, which can save a lot of money.

Question 3: How to calculate the size of soil ball by the height and crown width of seedlings,

1, trees are calculated as 6~8 times of DBH. If the DBH bifurcates below 1.3m, it is calculated according to the energy at 50CM from the ground.

2. The shrub is calculated as 1/3~ 1/2 of the natural crown.

3. Click the formula to calculate the diameter of palm branch soil ball and implement the tree quota. Diameter of soil ball =D+2R.

D- take the diameter of the palm plant R- take 20-30cm.

Question 4: How to determine the diameter of soil ball when the DBH and crown width of seedlings are known? The size of piles depends on the distribution of seedling roots and soil conditions. For precious trees, it is necessary to dig out the distribution of roots as much as possible in advance to determine the size of soil balls. Generally, the pilling range is 6-8 times that of DBH.

Question 5: Do you know how to calculate the soil ball at breast height? Cinnamomum camphora, Osmanthus fragrans, Luan tree in Huangshan Mountain, Xiangpao (Citron), Lechang/Michelia, Pu Shu, Acer truncatum, Magnolia grandiflora, Taxus chinensis, Podocarpus, Du Ying, Lagerstroemia indica, Osmanthus fragrans, Liquidambar formosana, cherry blossom, palm, elm, Liriodendron, Myrica rubra, red plum, cycad, fire.

Question 6: Urgent! ! ! Planting a soil ball tree only knows the crown width and does not know DBH. How to determine the diameter of soil ball? Answer: The soil ball of deciduous trees is 7-8 times that of DBH or 5-6 times that of ground meridian; Shrub canopy density 1/3.

But not all trees need to carry soil balls, and the specifications of soil balls can only reach about 4 times under normal construction. First, the cost of large seedlings of soil balls will come up, and second, four times the soil balls can ensure the survival rate of trees, so there is no need to increase them.

The cedar you mentioned belongs to the evergreen tree, so you must bring a soil ball. For evergreen trees, the quota is taken directly according to the height, and the specification quota of soil balls has been considered.

Question 7: What is the diameter of the soil ball when digging trees? This can't be repaired. The bigger the tree, the larger the diameter of the soil ball, otherwise it is difficult to survive.

Question 8: How to determine the diameter of the soil ball when the planting sleeve is fixed? Is there any basis? Generally speaking, the diameter of the soil ball is 6-8 times that of the trunk. If you say 1.5~2 times, don't mislead others. You can get a mud ball with a diameter of 40 cm and a DBH of 20 cm to see what the survival rate is ... speechless.
