[0039] The working principle of the bag-in-bag planting device for slope ecological restoration of the utility model will be described in detail below. Figs. 1-3

[0040] The slope has problems such as inclined gradient, thin soil layer and poor nutrients, so it is difficult for plants to grow and be planted. Therefore, artificial auxiliary measures are needed to increase the substrates conducive to the growth of plants on the slope, and plant plant species that are more resistant to drought, tolerant to barren and stable in growth, and then take measures such as watering, fertilizing and weeding in the later period, so as to gradually promote the restoration of slope vegetation and the formation of ecological landscape. The working principle of the bag-in-bag planting device for slope ecological restoration of the utility model is as follows. ​

[0041] 1. According to the characteristics of the slope, the moisture-retaining blanket, moisture-retaining film or water-permeable weed-proof film can be made into a cushion layer 1 of 1m*1m, 2m*2m or other sizes. 5-9 round holes are punched around and in the middle of the cushion layer 1. The hole size is about 5mm-10mm and the edges are sealed with stainless steel rings. When installing and fixing on the slope, use anchor rods, steel bars or stainless steel ropes to pierce the holes and fix them to the soil or the slope lattice beam.

[0042] 2. Setting of inner pockets 3: Inner pockets 3 of different sizes such as 20cm*13cm, 15cm*13cm, and 11cm*10cm are sewn on the cushion layer 1 (selected according to the size of the seedlings cultivated on the market). 8-9 inner pockets 3 are sewn on the cushion layer 1 of 1m*1m, and arranged in a "pin" shape. They are used to directly place and fix the nutrient bag seedlings or nutrient cup seedlings cultivated in the nursery, or to place seeds so that the plants will not fall over or fall. Such upper and lower staggered placement is conducive to the full absorption and upper and lower conduction of water, and improves the vegetation coverage. The material can be made of highly absorbent microfiber cloth or non-woven fabric, etc. The cushion layer 1 at each inner pocket 3 position is perforated as a root-penetrating water hole. The number of holes is 3-5, and the diameter of the hole is about 5mm-10mm, which can meet the requirements of water penetration into the slope soil and plant roots directly penetrating into the slope soil, forming an integrated nutrient space.

[0043] 3. The outer pocket 2 is set up: according to the position of the inner pocket 3, in the order of the herringbone, a large outer pocket 2 is sewn in a row.

The outer pocket 2 can be directly used to fill the matrix, reducing the construction procedure on the slope (the conventional procedure is to fill 1 / 3-1 / 2 of the matrix, place the seedlings, and then fill the matrix. This requires one hand to support the seedling and the other hand to fill the matrix, which is inconvenient to construct). The process is simple with respect to the procedure and is more convenient to construct. At the same time, the matrix will not cover the base of the plant, and will not cause the plant to be planted too deeply to affect survival. In addition, for different locations of potholes, the pocket can be flexibly used to fill the substrate, with more or less or no filling, to meet the substrate requirements for plant growth, while making the slope surface smooth. In the absence of substrate, it can be directly used to retain water and absorb and conduct moisture.
