Description

Seed formula suitable for net hanging spray seeding and re-greening of southern slope

Technical Field

The invention relates to a seed formula suitable for net hanging, spray seeding and re-greening on a southern slope. The method is suitable for the field of slope net hanging spray seeding greening.

Background

In actual construction, after a substrate mixed with a plurality of plant seeds is sprayed on a slope, herbaceous plants quickly sprout and grow and cover the slope, a good water and soil conservation effect is achieved, the color is light green, the slope is favored, and the slope is attractive, but most of woody plants such as shrubs lose weight soon after emergence of seedlings, even if a few survivors grow thin and weak and do not have climate, a vegetation community system formed on the slope is single in variety and lacks of layering, large-area degradation and extinction occur after 3-5 years, the ecological function is basically lost, the substrate layer is exposed again and suffers water and soil loss after being protected by the plants, and the ecological restoration engineering fails. None of these failures are due to incorrect and unscientific plant formulations.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: aiming at the existing problems, a scientific seed formula suitable for net hanging, spray seeding and re-greening on the side slope in the south is provided, so that a vegetation community which has symbiotic coexistence of grass, shrubs and flowers, high species abundance, normal interspecific competition and strong layering sense, can be continuously developed and performs by itself while effectively maintaining the stability of a matrix layer is formed.

The technical scheme adopted by the invention is as follows: a seed formula for spraying and re-greening after being hung on a net on a southern slope is characterized in that: pioneer plant seeds, companion plant seeds, landscape plant seeds and target plant seeds are mixed in a matrix layer sprayed on the slope surface of the side slope, wherein the pioneer plant adopts gramineous herbaceous plants such as tall fescue, bermuda grass and the like; the landscape plant adopts cornflower, impatiens balsamina and other flower plants; the target plant is shrub plant such as Ficus benjamina and Lespedeza virgata.

The pioneer plants quickly cover a part of the slope by utilizing the characteristics of quick germination, quick growth, developed root system and the like, show the mechanical effect of 'shallow layer reinforcement', maintain the stability of a matrix layer, simultaneously play the hydrological effects of sun shading, sun screening and water conservation, and provide a very suitable environment for the survival and growth of other subsequent plants; the associated plants further improve the soil structure and improve the soil fertility by utilizing the nitrogen fixation function of rhizobia and the like and the characteristic of converting the retrogression decay into fertilizer in the later period; landscape plants can show the landscape effects of the burnt and rotten mountains, full of vitality and rich in a short period, and can add vitality to the side slope and improve the ornamental value; the target plants establish motile vegetation communities with vigorous and durable vitality, self-circulation and sustainable development, good distribution and variation of season phase on the slope.

The pioneer plant seeds, the associated plant seeds, the landscape plant seeds and the target plant seeds are mixed according to the following weight parts:

according to the proportion, the pioneer plants further ensure the stability of the matrix layer through the mechanical action of 'shallow layer reinforcement' of the pioneer plants and create good conditions for the germination and growth of subsequent plants; then the slope surface presents colorful colors and strong ornamental value and can greatly improve the landscape effect of the surrounding environment; finally, as the target plants gradually grow up, the slope surface forms a ground cover plant consisting of herbs, the short shrubs are the middle layer, the high shrubs form a community structure with distinct and staggered top layers, strong vitality, high species abundance and self-reproduction, and meanwhile, enough space can be provided for invasion and survival of local wild plants, so that natural succession of the plant community is promoted, and the stability of the community is further ensured.

The pioneer plant seeds comprise the following components in percentage by weight:

tall fescue seeds: 50 percent; 12.5 percent of ryegrass seeds;

seeds of Bermuda grass: 12.5 percent; paspalum natatum seeds: 25 percent.

The vegetation formed by the proportion can coexist in symbiosis without influencing each other, achieves the effect of green color on the slope in one year, can fix water and soil as soon as possible, effectively prevents the matrix layer from being eroded by the slope runoff formed by rainwater, and more importantly, can reserve enough living space for the normal emergence and growth of other follow-up plants.

The companion plant comprises alfalfa.

The landscape plant seeds comprise the following components in percentage by weight:

cornflower seeds: 10 percent; coreopsis tinctoria seeds: 10 percent;

seeds of the senecio scandens: 10 percent; impatiens balsamina seeds: 40 percent;

and (3) sulphur chrysanthemum seeds: 20 percent; cockscomb seed: 10 percent.

The landscape plants have the characteristics of drought resistance, heat resistance, barren resistance, long flowering phase, complete flower colors and the like, and are very suitable for the side slope and the land environment. By using the proportion, not only can colorful landscape effects of the side slope be displayed and the ornamental value be improved, but also normal interspecific competition with other species can be kept without mutual interference.

The target plant seeds comprise the following components in percentage by weight:

seed of Fiveleaf akebia: 15.4 percent; seed of the hippophae rhamnoides: 15.4 percent;

seeds of lespedeza virgata: 15.4 percent; locust seeds: 7.7 percent;

amorpha fruticosa: 7.7 percent of seeds; semen cassiae seeds of parachui: 28.4 percent.

The target plant seeds have the excellent characteristics of easy seed obtaining, high germination rate, high growth speed, developed root system, barren resistance, drought resistance and the like. By adopting the proportion, the purposes of normal, non-interacting and symbiotic coexistence of interspecific competition can be achieved, the community structures of the second level and the third level can be established in the side slope space, the change of the season phase can be obviously reflected, and the stable sports vegetation community is formed.

The invention has the beneficial effects that: the invention can establish a diversified vegetation community system with rich colors, strong layering and good dislocation on the surface of the side slope, and the system has higher ornamental value, and the community structure combination is very stable and can be developed continuously.

The herbaceous plants covered on the slope surface can reduce direct impact damage of raindrops on the slope surface and can also reduce scouring of runoff, and the root systems of the herbaceous plants which are distributed in the matrix and are subjected to complex disk binding and different depths, the wire netting and the matrix layer form a multidimensional reinforcement complex together, so that the stability of the matrix can be obviously enhanced.

The invention has scientific proportioning, leaves enough living space for the normal emergence and growth of each plant, and keeps normal interspecific competition among the plants without mutual interference.
