Why Choose a Hydraulic Seeder for Slope Greening

Slope protection greening is a difficult task, so it needs the help of soil spraying machine. Soil spraying machines can spray mixed slurry of grass seed, fertilizer and wrapping material. Here are difficulties of slope greening:

1. Lack of conditions for vegetation survival.

Soil and nutrients are necessary for the growth of vegetation. The slope protection has poor soil, so it is not possible to plant vegetation directly. In addition, the rock mass has poor water retention function and few activated nutrients. Therefore, the vegetation root system is difficult to absorb enough water and nutrients from the slope rock layer.

2. Revetment slope is steep.

The designed slopes of highways and mines are above 1: 0.75, and even stand upright. The rainwater runoff speed is high on the slope, which can easily cause erosion in high rainfall areas. And soil particles brought by the natural weathering and rainwater are difficult to retain on the slope. Due to the hydraulic and gravity, they will accumulate at the foot of the slope. Moreover, rainwater can’t stay on the slope, which makes the vegetation difficult to live.

3. Natural ecological conditions are harsh.

The rocky slope is not covered by the soil layer and lacks moisture. The rock surface temperature is high in the direct sunlight. Even if seeds are in the rock gap, it will be difficult to germinate.

Application of Hydraulic Mulch Machine

Hydro-seeding has become an effective method of vegetation construction in highway slope greening, mine greening, desert management, riverbank protection. The hydroseeder has gradually replaced the position of dry sprayer and concrete pump. To a certain extent, the hydraulic seeding machine solves the low efficiency and high cost of dry sprayers.

Apart from the application of slop greening, hydraulic seeding machine also applies to large area lawns, such as golf course lawns, sports field lawns. Before seed germination treatment, it needs to hydraulic seeding. Add fiber binder, fertilizer and water, and mix into a certain proportion of mixed pulp. Then hydraulic seeding machine sprays mixture to the soil. In addition, after spraying, a uniform covering layer is formed on the ground. The cover consists of fiber, colloid, and topsoil. The cover layer can not only reduce water evaporation, but also provide good water, nutrients and shade environment for seed germination. The cover also can prevent the seeds from washing away by wind and rain, and from carrying off by birds.
