Embodiment 1

[0029] 1) Arranging the planting site according to the conventional method: including clearing the debris on the flat ground and the gravel and debris on the slope surface, and leveling the slope surface;

[0030] 2) Digging planting troughs: Excavate multiple strip-shaped planting troughs with a depth and width of 30cm along the horizontal contour slope on the planting site, and the row spacing of each planting trough is 50cm;

[0031] 3) Nutrient soil bottom: Pave nutrient soil in the planting tank, the bedding amount is about half of the depth of the planting tank, and then spread it evenly; than mixed;

[0032] 4) Pulping: Mix water, planting soil, and water-retaining agent in a weight ratio of 100:60:0.1 to make slurry for later use;

[0033] 5) Cutting: the cutting height of vetiver seedlings is 20-25cm, and the root length is 10-15cm;

[0034] 6) root dipping and paste treatment: use the mud in step 4) to carry out root dipping and paste treatment on the roots of the ...

Embodiment 2

[0040]Each step is the same as in Example 1; wherein, the nutrient soil in step 3) is mixed by planting soil and calcium magnesium phosphate fertilizer in a weight ratio of 1:0.075; the weight ratio of matrix soil and water-retaining agent in step 7) is 1:0.0015 The substrate soil is formed by mixing planting soil, sawdust, humus, and ternary compound fertilizer with a concentration of 35% in a weight ratio of 6:1.5:3:1.5.

Embodiment 3

[0042] Each step is the same as Example 1; wherein, the nutrient soil in step 3) is mixed by planting soil, calcium magnesium phosphate fertilizer in a weight ratio of 1:0.1; the weight ratio of matrix soil and water-retaining agent in step 7) is 1:0.002 , the matrix soil is made by mixing planting soil, sawdust, humus, and ternary compound fertilizer with a concentration of 40% in a weight ratio of 7:2:4:2.

[0043] In each of the above embodiments, the water-retaining agent is a general agricultural and forestry polymer water-absorbing resin with a water absorption rate of 150-300; the calcium-magnesium phosphate fertilizer can be effective P 2 o 5 Content ≥ 20%, effective MgO content ≥ 12%, soluble SiO 2 Sandy calcium magnesium phosphate fertilizer with ≥20%, alkali content (calculated as CaO) ≥45%, and moisture ≤1.5% can also be effective P 2 o 5 Content ≥ 20%, effective MgO content ≥ 12%, soluble SiO 2 Powdered calcium magnesium phosphate fertilizer ≥20%, alkali conte...

Abstract

The invention discloses a soil-fixation and slope-protection method by planting vetiver grass, belonging to a planting method of vegetation and aiming to provide a method for administering hungriness areas by utilizing the property of the vetiver grass and planting vetiver grass in the surface of bare hills and lands, man made side slopes, tailing areas, and the like. The technique proposal comprises the following steps: sorting out fields, digging plant grooves, filling in nutrient soil, cutting, dipping in root, wrapping slurry, making vegetation pocket seedlings, transplanting the vegetation pocket seedlings and then maintaining. The method has the advantages of improving the survival rate of the vetiver grass by about 30%, having good effect in preventing water loss and soil erosion, fixing soil and protecting slopes, and effectively improving geomorphologic landscape; the method can be widely used for revegetation in bare hills and lands, hungriness areas and hammada areas of the karst region, fixing slopes and greening of man made side slopes, and administering earth surface of tailing areas, etc.

Description

Technical field: [0001] The invention relates to a method for planting vetiver, in particular to a method for planting vetiver on desert land and forming vegetation on the ground. Background technique: [0002] As we all know, although our country has a vast area, the phenomenon of land desertification and rocky desertification is relatively serious. In recent years, with the rapid development of infrastructure such as roads, railways, industrial and civil buildings, mines, and water conservancy projects, the natural landscape has been greatly damaged, and a large number of man-made slopes formed after construction are likely to cause water and soil erosion, which brings great harm to the ecological environment. new hazards. Surfaces such as desert land, rocky desert land, and man-made slopes have the following characteristics: ①There is a certain slope; ②Natural vegetation has been destroyed; ③Mostly barren soil or broken rocks, site conditions, water and fertilizer condit...
