Plant matching scheme and pretreatment method applied to lateritic red earth slope protection

Abstract

The invention relates to a plant matching scheme and pretreatment method applied to lateritic red earth slope protection. The principles of combining fast growing and slow growing plants, combining legume trees and shrubs and gramineous and herbaceous plants and combining shallow-rooted and deep-rooted plants are followed, and six water and soil conservation plants common in the south are selected and matched in parts by mass: 30 parts of cynodon dactylon, 25 parts of paspalum notatum, 15 parts of festuca arundinacea, 14 to 16 parts of white tephrosia, 12 to 14 parts of leucaena leucocephala and 2 to 3 parts of acacia confusa. In addition, the invention further provides a plant seed pretreatment method applied to lateritic red earth slope protection. The method specifically comprises the following steps: (1) grinding seed skin with stirring; (2) preparing a seed pretreatment solution; (3) impregnating and air-drying herbaceous plant seeds; (4) impregnating and air-drying tree and shrub seeds. The method is convenient to operate and low in cost, and the adopted vegetational plants are readily available, reasonable in matching, high in growth speed and adaptability and particularly applicable to the ecological protection of a southern lateritic red earth slope.

Description

technical field [0001] The invention belongs to the fields of soil and water conservation and botany, and in particular relates to a plant proportioning scheme and a pretreatment method suitable for red soil slope protection, and is particularly suitable for red soil slopes in southern China. Background technique [0002] The construction of highways, railways, water conservancy and municipal gardens often forms large areas of exposed slopes, and the ecological protection of exposed slopes is one of the key points of such projects. At present, the industry generally follows the empirical method of mixed planting for ecological protection of bare slopes. Due to the lack of understanding of the ecological environment, plant growth conditions and plant species around the slope, the proportion of plants in the process of ecological protection of the slope mainly relies on engineering experience, lacking the guidance of scientific theoretical basis, and there are often plant spec...

[0005] In addition, the pretreatment methods for plant seeds in the industry are relatively simple, usually only soaking in water, which has a poor effect on promoting the germination and survival of plant seeds
