Problems solved by technology

Whether these two methods use sandy soil, clay soil or organic matter, they cannot fully simulate the soil environment required for normal growth of plants in nature, especially they cannot effectively solve the problem of the activity of non-cultivated soils.
Although the above-mentioned greening methods have been widely used, the application status is good or bad, the application effect is unstable, and the persistence of plant growth is also poor, especially when applied to high and steep hard rock slopes, the greening effect is not ideal.

Embodiment 1

[0007] Embodiment 1: formula (volume ratio %) of the present invention is as follows:

[0008] Organic Fertilizer 40

[0009] Organic Fiber 10

[0010] Fine-grained clay 49.6

[0011] Water retaining agent 0.1

[0012] Compound fertilizer 0.3

[0013] Mix the organic fertilizer, organic fiber, fine-grained clay, water-retaining agent and compound fertilizer in the above ratio evenly, and then fully mix with the seeds. The seeds are three kinds of teff, bermudagrass and white clover, and spray them with equal thickness through a spraying machine. On a dolomite slope with a slope ratio of 1:0.5. The grass seeds began to germinate 12 days after the construction, and the lawn completely covered the slope after 50 days. After 2 growth cycles, the growth was good, and the artificial active soil did not slump.

Embodiment 2

[0014] Embodiment 2: the soil formula (volume ratio %) of the present invention is as follows:

[0015] Organic Fertilizer 30

[0016] Organic Fiber 20

[0017] Fine-grained sandy soil 49.3

[0018] Water retaining agent 0.2

[0019] Compound fertilizer 0.5

[0020] Mix the organic fertilizer, organic fiber, fine-grained sand, water-retaining agent and compound fertilizer in the above ratio evenly, and then fully mix with the seeds. The seeds are made of tall fescue, bermudagrass and amorpha, and are passed through a spraying machine with equal thickness. Spray on the sandstone slope with a slope ratio of 1:0.3. After 10 days of construction, the grass seeds began to germinate. After 45 days, the lawn completely covered the slope. After one growth cycle, the growth was good, and the artificial active soil did not slump.

Embodiment 3

[0021] Embodiment 3: formula (volume ratio %) of the present invention is as follows:

[0022] Organic Fertilizer 20

[0023] Organic Fiber 20

[0024] Farmland soil 58.8

[0025] Water retaining agent 0.5

[0026] Compound fertilizer 0.7

[0027] Mix the organic fertilizer, organic fiber, farmland soil, water-retaining agent and compound fertilizer in the above ratio evenly, and then fully mix with the seeds. The seeds are two kinds of tall fescue and bluegrass, which are sprayed on the slope with equal thickness by spraying machine. 1:0.75 shale and sandstone interbedded rock slope. After 13 days of construction, the grass seeds began to germinate. After 60 days, the lawn completely covered the slope. After one growth cycle, the growth was good, and the artificial active soil did not slump.

Abstract

The invention provides a man-made active soil comprising organic fertilizer to make rock slope green composed of organic fertilizer, organic fiber, fine-particle soil, water-retaining agent and compound fertilizer, in preparing ratios of (volume percentage): 20-40, 10-30, 30-60, 0.1-0.5, and 0.3-0.8, respectively. The soil can not only simulate the activity of the farming soil, also provide soil, water nutrient and microbe environments for plant growth, and has a certain cohesive force by itself, and can not make the soil harden, and depends on the anchor rod and the net to form a stable interger which close adheres to the rock slope.

Description

technical field [0001] The invention relates to an artificial active soil capable of meeting the needs of plant growth and development, in particular to an artificial active soil which utilizes organic fertilizers to green rock slopes. Background technique [0002] At present, for the greening of rock slopes, the spray-mixed vegetation method and the organic substrate injection method are commonly used. The spray-mixed vegetation method is divided into sand series and clay series; the organic substrate spray method is also divided into all organic matter series, organic matter and clay. Mixed series, the organic matter mainly adopts fresh peat. No matter whether these two methods use sandy soil, clay soil or organic matter, they cannot completely simulate the soil environment required for normal growth of plants in nature, especially they cannot effectively solve the problem of the activity of non-cultivated soil. Although the above-mentioned greening methods have been wide...
