Embodiment Construction
[0024] In the k100-k800 section of Jianghe Expressway in Guangdong, the weathered granite cutting slope is used for ecological restoration and soil and water conservation by spraying fern-based guest soil spraying technology. The area has a long sunshine period and a subtropical climate with an average annual rainfall of 1100-1650mm and a longest continuous drought of 43 days. The average temperature in January is 12.3°C and the average temperature in July is 29.1°C. The rocky slope is 28 meters high, with a slope of 63°. There are two levels of platforms, and the slope area is 1800m 2 .
[0025] The fern plant selected for spraying in this embodiment is Osmanthus osmanthus, and the sporangia are born in the upper and middle parts of the lateral veins of each group of leaves. The mature spores are collected in mid-August, packed in envelopes, and put into a 4 ° C refrigerator for later use. After cleaning the slope surface, drill bolt holes evenly at intervals of one meter on...
