Problems solved by technology

Second, the soil is compact and compacted, with high bulk density, poor permeability and water holding capacity, which is not conducive to the growth of soil microorganisms and tree roots
Third, turfgrass and ground cover plants cannot effectively improve soil conditions, and there will be situations in which they compete with trees for water and nutrients
When there is no vegetation around the trees, there will be bare ground, which will easily lead to dust and soil erosion
Fourth, a large number of litter, leaves, weeds, etc. are removed or burned, and nutrients cannot return to the soil normally to achieve material circulation, which also increases the cost of management and maintenance
[0005] However, the scope of application of these existing technologies is not very specific, and the formula has many components, the production process is relatively complicated, and the production time is relatively long. The present invention aims at the above problems and provides a kind of soil conservation and beautification mainly for urban garden trees. Organic mulch on the ground surface, the formula components are simple and easy to obtain, and the production process is highly operable

Embodiment 1

[0026] 1. Select newly planted camphor trees as garden tree species, a total of 30 trees, diameter at breast height of 9-10cm, crown width of 3.0-3.5m, and the growth condition is acceptable.

[0027] 2. The pine and cypress bark, pine needles and Trichoderma water-dispersible granules are evenly mixed according to the weight ratio of 66%: 29%: 5% as an organic covering.

[0028] 3. Divide 30 camphor trees into two groups on average, called the improved group and the control group, and do the following treatments respectively: remove the weeds in the tree crown projection range of the improved group, and evenly lay the organic mulch on the ground surface. For the surface area projected vertically, keep a distance of 8cm between the covering and the base of the trunk, and the covering thickness is 7cm, which will be supplemented by 3cm in the next year. The control group received no treatment.

[0029] 4. After covering for one year, measure the soil physical and chemical prop...

Embodiment 2

[0031] 1. Select the newly planted Magnolia magnolia as the garden tree species, a total of 30 trees, with a DBH of 7-8cm and a crown width of 2.0-2.5m. The growth condition is acceptable.

[0032] 2. The pine and cypress bark, pine needles and Trichoderma water-dispersible granules are evenly mixed according to the weight ratio of 70%: 25%: 5% as an organic covering.

[0033] 3. Divide 30 Magnolia magnolias into two groups on average, called the improved group and the control group, and do the following treatments respectively: remove the weeds in the tree crown projection range of the improved group, evenly lay the organic mulch on the ground surface, and the coverage range is the tree crown For the surface area projected vertically, keep a distance of 10cm between the covering and the base of the trunk, and the covering thickness is 10cm, and 2cm will be added in the next year. The control group received no treatment.

[0034] 4. After covering for one year, measure the so...

Embodiment 3

[0036]1. Select the newly planted tree pool type ginkgo as the garden tree species, a total of 20 trees, with a breast diameter of 7-8cm, a crown width of 2.5-3.0m, and the growth condition is acceptable.

[0037] 2. The pine and cypress bark, pine needles and Trichoderma water-dispersible granules are evenly mixed according to the weight ratio of 65%: 25%: 10% as an organic covering.

[0038] 3. Divide 20 ginkgoes into two groups on average, called the improvement group and the control group, and do the following treatments respectively: remove the weeds in the tree pool in the improved group, and evenly lay the organic mulch on the ground surface. Keep a distance of 5cm between the covering and the base of the trunk, and the covering thickness is 6cm, and add 2cm in the next year. The control group received no treatment.

[0039] 4. After covering for one year, measure the soil physical and chemical properties index and weed coverage rate, the results show that compared wit...

Abstract

The invention discloses an organic mulch on an earth surface of garden trees and an application method thereof and belongs to the technical field of garden planting. The organic mulch on the earth surface of the garden trees is prepared by mixing the following components in percentage by weight: 60-70% of pine bark, 25-30% of pine needle and 5-10% of Trichoderma water dispersible granule. By utilizing the organic mulch, water, fertilizer, gas and heat situations of the garden tree earth can be improved, weeds can be prevented from growing, and the purposes of retaining water and soil and optimizing environment can be achieved.

Description

technical field [0001] The invention relates to artificial vegetation in the technical field of garden planting and its application, in particular to an organic covering on the surface of garden trees and an application method thereof. Background technique [0002] With the rapid development of my country's economy and society and the continuous improvement of the level of urbanization, people's demand for improving and beautifying the environment is becoming more and more urgent. In many places, there is an upsurge of urban forest construction, and a large number of new green spaces abound. While the construction of urban green spaces has achieved great results, there are still many deficiencies. At present, there are mainly the following problems in terms of the soil habitat and management and protection methods of urban garden trees: First, most of the greening soil is mostly garbage soil and deep foundation pits. earth. The soil is barren, low in N, P and other nutrient...
