Seed formula suitable for southern slope net-hanging spray-seeding regreening

Abstract

The invention relates to a seed formula suitable for southern slope net-hanging spray-seeding regreening. The invention aims to provide a scientific seed formula suitable for southern slope net-hanging spray-seeding regreening, so as to form a vegetation community which has the advantages of grass-shrub-flower symbiotic coexistence, high species richness, normal interspecific competition and strong layering sense, and can be sustainably developed and self-successed while effectively maintaining the stability of a matrix layer. According to the technical scheme, the seed formula suitable for southern slope net-hanging spray-seeding regreening is characterized in that pioneer plant seeds, companion plant seeds, landscape plant seeds and target plant seeds are mixed in a matrix layer spray-seeded on a slope surface, wherein pioneer plants are gramineous herbaceous plants such as festuca arundinacea and cynodon dactylon; the landscape plants are flower plants such as cornflower and impatiens balsamina; and shrub plants such as indigofera multiflora and thunberg lespedeza are adopted as the target plants. The seed formula is suitable for the field of lope net-hanging spray-seeding greening.

Description

Technical field [0001] The invention relates to a seed formula suitable for spraying and sowing nets on southern slopes for re-greening. It is suitable for the field of slope greening and spraying with net. Background technique [0002] In the actual construction, it is often found that after spraying the substrate mixed with the seeds of more varieties of plants on the slope, the herbaceous plants germinate and grow quickly and cover the slope, playing a good role in soil and water conservation, and the color is green and the growth is gratifying. It has strong aesthetics, but it is also found that most shrubs and other woody plants die shortly after emergence. Even a small number of survivors are weak and non-climatic. The vegetation community system formed on the slope is single in variety and lacks layers. What is more serious is that a large area of ​​degradation and extinction will occur after 3 to 5 years, and the ecological function will basically be lost. After the subs...

[0002] In actual construction, it is often found that after the substrate mixed with more varieties of plant seeds is sprayed on the slope, the herbaceous plants germinate and grow rapidly and cover the slope, playing a good role in water and soil conservation, and the color is green and the growth is gratifying. It has strong aesthetics, but at the same time, it is also found that most shrubs and other woody plants die shortly after emergence. Even a small number of survivors are thin and weak, and the vegetation community system formed on the slope is single in variety and lacks layers. What's more serious is that after 3 to 5 years, there will be large-scale degradation and extinction, and the ecological function will be basically lost. After losing the protection of the ground cover, the substrate layer will be exposed again and soil erosion will occur, and the ecological restoration project will fail.

These failure cases are all caused by incorrect and unscientific plant formulas.
