A method of greening bare slopes by using native herbaceous plants

Abstract

The invention discloses a method of greening a bare slope by utilizing local herbaceous plants. The method comprises the following steps that the bare slope is cleaned, a net is fixed to the slop through anchor rods, and then plant growing matrix or casing soil is sprayed to the slope; when fruit clusters of thysanolaena maxima mature from the last ten-day of the May to the first ten-day period of the June, the fruit clusters of thysanolaena maxima are collected and threshed, and spikelet and caryopses of the thysanolaena maxima are obtained through screening; coconut chaff is placed into water and wetted, the coconut chaff is fished out after absorbing sufficient water, and the coconut chaff is evenly mixed with the spikelet and the caryopses, so that the spikelet and caryopses of the thysanolaena maxima absorb water; the coconut chaff mixed with the spikelet and caryopses of the thysanolaena maxima is mixed and stirred with pigeon pea seeds, fertilizers and water to make a spray-seeding material, the spray-seeding material is sprayed to slurry of the slope, and then the slope is covered with non-woven fabrics for maintenance until the slope is full of the thysanolaena maxima and pigeon pea plants. The method of greening the bare slope by utilizing the local herbaceous plants is simple to operate, high in greening success rate, obvious in greening effect and capable of achieving a green ecology and landscape effect.

Description

technical field [0001] The invention belongs to the field of environmental ecological restoration, and in particular relates to a method for greening exposed slopes by using native herbs. Background technique [0002] With the rapid development of my country's economy, the impact on the ecological environment is also increasing. For example, the construction of expressways requires the use of a large amount of sand and gravel materials due to the exposed slopes caused by excavation and the construction of buildings and infrastructure. As for the abandoned quarries or mines, with the rapid economic and social development, the country has accelerated infrastructure construction in recent years, especially in the economically developed southern region, where investment is large and the construction period is longer. During the construction of highways, railways, water conservancy, and mines, it is often necessary to excavate mountains and a large number of exposed slopes will ap...

Problems solved by technology

At present, domestic slope greening grass species mostly use imported grass species, and there are few types, which do not meet the requirements of various terrain conditions.

Moreover, due to the poor ecological adaptability of some introduced grass species, the vegetation on the slopes that have been greened will be degraded.
