The studies on covering grass on the field of orchard shows that grass cover can keep warmth, moisture of the field, regulate soil structure, increase organic matter, and fertilize the land to improve apricot s yield and quality.

Grass cover can reduce water evaporation.

The study of water-saving effects in orchard covering with grass was carried out in Zhangye city.

The effects of different water retention treatments such as covering with veil, covering with grass and using water retention preparation are studied.

Analysis of the seeding tests on the roadbed in the Yangbajing Section of Qinghai-Tibet Railway;

Application of the three-dimensional net seeding in the slope protection construction;

The article expounds the soil and water conservation principle of slope protected by seeding grass in 3D Geomat.

Based on the analysis of the application of 3-D geonet sprig-grass in regulation engineering of downstream Beijiang River,the conclusion is drawn that this technique can not only satisfy the need of sideslope reinforcement,but also improve the ecological environment of the river bank and promote environment protection, thus it is a practical technique worthy of popularizing.

Based on the validity assessment on the reinforcing engineering of the side slope of a bank adopting three-dimensional geonet sprig-grass,it is considered that this technique can not only meet the demand of soil stabilization and slope protection,but also improve the ecological environment of the bank,thus it is a practical technique worth popularizing.
