Problems solved by technology

Moreover, if the filling slope of the expressway uses mountain soil, the soil quality is poor, it lacks fertilizer and does not retain water, which is not conducive to the growth of plants. Properly improve the substrate in order to achieve a good effect of vegetation restoration
[0008] Based on the above reasons, the current conventional seed propagation technology cannot meet the large demand for mulberry seedlings for vegetation restoration in difficult habitats. It is necessary to seek a breeding technology that improves the germination rate and survival rate of mulberry seeds and a substrate that retains water and fertilizer to ensure Availability of seedlings and successful rapid restoration of vegetation in difficult habitats

Embodiment 1

[0025] Example 1: Afforestation of the hillside soil fill slope of a certain expressway

[0026] 1. Nursing

[0027] (1) In late June, collect the mature fruit of the mulberry tree, place it in a cool and ventilated place for 7 days, wash the seeds, store them in a refrigerator at 4-5°C for 20 days, take out the seeds of the mulberry tree, soak them in room temperature water for 12 hours and filter The seeds are soaked in water at 45° C. for 10 minutes, then soaked in 0.25% carbendazim aqueous solution for 20 minutes, and then filtered out to obtain mulberry seeds to be sown.

[0028] (2) The sowing substrate is obtained by mixing river sand: coconut bran at a mass ratio of 9:1. The mulberry seeds to be sown that step (1) obtains are sowed on the sowing substrate in the permeable sowing basin, covered with a 1.5 cm thick sowing substrate, and then covered with a layer of plastic film on the sowing substrate, placed in the shade shed, Keep the substrate moist and control the ...

Embodiment 2

[0036] Example 2: Greening of exposed slopes in a tailings area

[0037] 1. Nursing

[0038] (1) In late August, collect the mature fruit of mulberry tree, put it in a cool and ventilated place for 3 days, wash out the seeds, refrigerate it at 4-5°C for 30 days, take out the mulberry tree seeds, soak them in room temperature water for 6 hours and filter The seeds are soaked in water at 42° C. for 20 minutes, then soaked in 0.2% carbendazim aqueous solution for 30 minutes and then filtered out to obtain mulberry seeds to be sown.

[0039] (2) The sowing substrate is mixed according to the mass ratio of river sand: coconut bran is 8:2. The tree seeds to be sown that step (1) obtains are sowed on the sowing substrate in the permeable sowing basin, covered with a 1 cm thick sowing substrate, and then covered with a layer of plastic film on the sowing substrate, placed in the shade shed, kept The substrate is moistened and the temperature in the shade shed is controlled to be 32-...

Abstract

The invention discloses a method for greening a bare slope by using paper mulberries. According to the method, mature seeds of the paper mulberries are treated, seeding matrix and breeding matrix areimproved, so that the germination rate of the seeds is greatly improved, the survival rate can reach more than 90%, the cultivated paper mulberry bag seedlings are developed in root systems and strongin growth, the seedlings can be out planted for target planting after 3-4 months, the crown breadth formed by the paper mulberries can basically cover the slope 90-120 days after the planting, the requirements of greening bare slopes, such as barren mountains, tailings, slopes and the like, can be efficiently and quickly met, the maintenance and management after planting is simple, and a large amount of labor and material resources are saved. The method has the advantages of simple operation, high greening success rate and obvious greening effect, and can rapidly achieve the effects of greening and beautifying the environment.

Description

technical field [0001] The invention belongs to the technical field of environmental ecological restoration, and in particular relates to a method for greening exposed slopes with mulberry trees. Background technique [0002] Bare slopes will bring a series of environmental problems, such as soil erosion, landslides, mudslides, deterioration of local microclimate, and destruction of biological chains. It takes a long time to restore the vegetation on the bare slope formed by the engineering construction relying on the power of nature itself. According to relevant literature, it takes 40-100 years to restore the damaged vegetation only through the power of nature. [0003] With the rapid development of the economy and society, the country has accelerated the infrastructure construction. In the construction of roads, railways and other places that need to be filled, in order to save land resources, the mountain soil is often directly used for backfilling. Mountain skin soil i...
