How to grow iris on a slope

Abstract

The invention discloses a method for planting iris tectorum maxims on a slope. The method comprises the steps of: clearing up a slope surface, namely paving a nutrient soil layer and a gravelly soil layer sequentially on the sloping surface from bottom to top; pouring ecologic concrete and covering the ecologic concrete with a plastic film for maintenance, wherein the ecologic concrete is obtained by mixing broken stones, cement, silicon dioxide micro powder or fly ash, a water reducer and water according to a certain ratio, and stirring the materials uniformly; planting iris tectorum maxims, namely fixing rootstocks of the iris tectorum maxims on the ecologic concrete by using wire meshes and performing maintenance, wherein the rootstocks of the iris tectorum maxims are pretreated before planting: soaking a mixture of orange peel and a traditional Chinese medicine namely viola philippica in ethanol and performing extraction to obtain a filtrate, and soaking root tips of the rootstocks of the iris tectorum maxims in the filtrate; and performing watering maintenance after planting. The method disclosed by the invention enriches the varieties diversity of plants cultivated on the ecologic concrete, and the rootstocks of the iris tectorum maxims are strong in tillering capability, grow fast and have relatively high ornamental values; and planting the iris tectorum maxims on the slope not only can effectively fixing slope soil and improve the ecological environment, but also can beautify the environment.

Description

Technical field [0001] The invention relates to the field of ecological protection. More specifically, the present invention relates to a method of growing irises on a side slope. Background technique [0002] With the acceleration of urban construction, some landscape ecological problems have appeared in urban river revetments, such as destruction of original vegetation and soil erosion. In order to solve the above problems, the traditional engineering measures adopted measures include directly planting aquatic plants in the riparian zone, using ecological bag technology to protect the slope and planting plants, using gabion to construct an ecological riparian zone, and artificial hardening of the bank. Directly planting aquatic plants in the riparian zone is not resistant to rain erosion, and the function of conserving water and soil is not ideal; although the ecological bag slope protection technology solves the problem of vegetation planting to a certain extent, it has a goo...

Problems solved by technology

Planting aquatic plants directly on the river bank is not resistant to rain erosion, and the function of water and soil conservation is not ideal; although the ecological bag slope protection technology solves the problem of vegetation planting to a certain extent, and has a better function of water and soil conservation, it is also not resistant to rain erosion as time goes by , its functions of water and soil conservation and water purification are also gradually lost; although the gabion construction of ecological river bank belts and artificial hardened bank revetments can fix the soil, they will directly destroy the basis for the survival of river bank vegetation, and the vegetation ecosystem will be destroyed and degraded.
