Problems solved by technology

[0002] The soil of urban street trees has long been polluted by various factors such as vehicle exhaust, construction waste, and domestic waste. In northern cities, a large number of snow-melting agents with high salt content are used after snowfall in winter, causing serious soil pollution. Some sanitation workers put a large amount of snow-melting agents on the other side In the tree weir, after the melting of snow water, the soluble salts in the soil where the trees grow are too much, the osmotic potential of the soil solution is reduced, and the plants are in a state of physiological drought, which inhibits the growth of plants; in addition, as the trees grow up, the tree weirs are relatively narrow Small tree pools are also difficult to meet the growth needs of tree roots; for the cleanliness of the urban environment, fallen leaves and residual branches are swept away, and the soil organic matter content is very low; Salinization and other problems, manifested as root growth retardation, late greening and germination, yellow leaves and scorched leaves, and severe pruning or whole plant death

Embodiment 1

[0041] Such as figure 1 Shown, the invention provides a kind of nursery stock rejuvenation method of street tree, comprises the following steps:

[0042] Step 1. Digging rejuvenation holes: Dig 4 rejuvenation holes on the outside of the edge of the tree weir. The size of the rejuvenation holes is: 50cm×80cm×60cm;

[0043] Step 2. Backfilling with rejuvenation soil: mix the street tree rejuvenation matrix and the original soil according to the volume ratio of 1:4, backfill and compact;

[0044] Wherein, in parts by weight, the street tree rejuvenation matrix is ​​prepared from the following components:

[0045] 10 parts of peat, 35 parts of decomposed garden waste, 5 parts of perlite, 8 parts of slow-release fertilizer and 0.1 part of mycorrhizal fungus.

[0046] Experimental group: According to this plan, 20 street trees on one side of the road were rejuvenated;

[0047] Control group: 20 street trees on the other side of the road were left untreated;

[0048] Results: Aft...

Embodiment 2

[0052] The invention provides a kind of nursery stock rejuvenation method of street tree, comprises the following steps:

[0053] Step 1. Digging rejuvenation holes: Dig 6 rejuvenation holes on the outside of the edge of the tree weir. The size of the rejuvenation holes is: 50cm×80cm×80cm;

[0054]Step 2. Backfilling with rejuvenation soil: mix the street tree rejuvenation matrix and the original soil according to the volume ratio of 1:5, backfill and compact;

[0055] Wherein, in parts by weight, the street tree rejuvenation matrix is ​​prepared from the following components:

[0056] 15 parts of peat, 45 parts of decomposed garden waste, 10 parts of perlite, 12 parts of slow-release fertilizer and 0.14 part of mycorrhizal fungus.

[0057] According to this plan, the 20 street trees on one side of the road will be rejuvenated, and the 20 trees on the other side of the road will not be treated. After 60 days, the branch luxuriance of the 20 trees on one side of the road is ob...

Embodiment 3

[0064] The invention provides a kind of nursery stock rejuvenation method of street tree, comprises the following steps:

[0065] Step 1. Digging rejuvenation holes: dig 5 rejuvenation holes outside the edge of the tree weir, the size of the rejuvenation holes is: 50cm×80cm×70cm;

[0066] Step 2. Backfilling with rejuvenation soil: mix the street tree rejuvenation matrix and the original soil according to the volume ratio of 1:4, backfill and compact;

[0067] Wherein, in parts by weight, the street tree rejuvenation matrix is ​​prepared from the following components:

[0068] 10 parts of peat, 40 parts of decomposed garden waste, 5 parts of perlite, 10 parts of slow-release fertilizer and 0.14 parts of mycorrhizal fungus;

[0069] Step 3, dig loosening soil hole: remove 20cm of the original soil between the rejuvenation hole and the stem of the street tree, as the criterion not to injure the tree roots;

[0070] Step 4, laying a layer of 4cm branches after pruning street tr...

Abstract

The invention discloses a nursery stock rejuvenation method for border trees. The nursery stock rejuvenation method includes the following steps: digging rejuvenation caves in the outer sides of tree weirs; evenly mixing a border-tree rejuvenation base material with original soil according to the volume ratio of 1: (4-5), backfilling the caves, and compacting the soil. The border-tree rejuvenation base material comprises, by weight, 10-15 parts of grass carbon, 35-45 parts of rotten garden waste, 5-10 parts of perlite, 8-12 parts of slow-release fertilizer and 0.1-0.14 part of mycorrhizal fungus. The nursery stock rejuvenation method has the advantages that loose rejuvenation soil with rich nutrition, long-lasting fertilizer effect, high water-holding capacity and high breathability is provided for the border trees, and a health growth environment is provided for plant systems, so that adverse effect caused by external environment is relieved effectively, tree vigor is enhanced, and complete crowns and luxuriant foliage are achieved.
