Introduction:It is the most common practice by spraying grass seed with fertilizer to soil surface,it minimizes the inconvenience
of traditional turfing in the sense that hydroseeding can also easily be applied to ragged soil surface.Moreover, it is economical and fulfill the function of erosion controlin minimum extent.In recent years,hydromulching is introduced,it is an improved method of hydroseeding that contains the use of paper mulch in the spraying process,not only fertilizer is mixed into the spraying materials,paper mulch is also added in order to provide a better moisture capacity of the spraying materials.
Advantages：
1.Efficient
For the same area, compared with the traditional laying turf method, number of workers required can be reduced from 100 to 2 and the construction period is shortened in a large extent.
2.Economical
Labour cost can be greatly reduced.
3. High Performance
Grass seeds can be evenly distributed so as to reach the purpose of soil protection and landscaping.
Seeds require water to start the germination process. The slurry hydroseeding materials absorb water and allow storage of water to provide sufficient moisture available for seed
to germinate .
4. Flexible
Fertilizers can also be used with seeds at the same time when hydroseeding is undertaken. During winter, a cover crop of millet or ryegrass can also be applied in the mixture to give
a fast germinating ground cover until the desired grass established.
