Embodiment 1
[0046] Implementation location: Langya Town, Huangdao District, Qingdao City, Shandong Province
[0047] First, use an excavator to roughly repair the slope of the embankment, clean up debris, bricks, branches and other sundries in the 0-30cm soil layer, take the area between the two steps as the work area, rake the whole, trim the slope, and then do it manually Fine trimming, crushing large soil clods on the surface to ensure that the particle size of the soil clods is ≤1cm. Repair the joints of the water-retaining stones on the top of the slope to ensure that water does not flow to the slope. After the light rain, acetochlor was sprayed with a pesticide vehicle, the spraying concentration was 150ml / mu of acetochlor emulsifiable concentrate, spraying backward, and sowing was carried out 65 days after spraying.
[0048] When sowing, according to: urea 5g / m 2 ;Superphosphate 10g / m3 with an available phosphorus content of 18% 2 ;Potassium sulfate with an effective potassium c...

[0052] Firstly, the excavator roughly trims the slope of the river embankment, clears debris, bricks, branches and other sundries in the 0-30cm soil layer, takes the area between the two steps as the working area, rakes the overall level, trims the slope, and then manually fine-tunes the slope. Trimming, crushing large soil clods on the surface, so that the particle size of the soil clods is ≤1cm. Repair the joints of the water-retaining stones on the top of the slope to ensure that water does not flow to the slope. After the light rain, acetochlor was sprayed with a pesticide vehicle, the spraying concentration was 150ml / mu of acetochlor emulsifiable concentrate, spraying backward, and sowing was carried out 65 days after spraying.
