[Objective] Coconut chaff matrix, rice straw, wheat straw, reed straw and corn straw were used to make a new type of ecological blanket after crushing treatment, which provided new methods and ideas for the treatment of ecological environment. [Method] 12 kinds of ecological blanket configuration were designed and made, and the effect of laying ecological blanket on surface soil moisture content was analyzed. [Result] In the data processing, it was found that the ecological blanket had a very good effect on maintaining soil moisture content and inhibiting soil water evaporation. Compared with the litter under the plantation, the maximum average water holding rate of the ecological blanket was 2.07 times that of the maximum average water holding rate of the plantation. [Conclusion] The practical application scenarios and methods of ecological blanket are summarized. In the treatment of desertification and desert, T4, T5 and T12 are selected to cooperate with grass grids to prevent wind movement and cover soil on the surface. When there is no special ecological management requirements in general areas, T12 and T4 can be used to maintain soil water content. It is suggested that T1, T4 and T8 should be selected for the restoration of bare land in mountain forests. If the average rainfall is large and prone to flood areas recommended configuration T1, T4, T8. [ABSTRACT FROM AUTHOR] |
