Abstract

The present invention relates to a constructing and planting method for slope lawns of southern highways, which belongs to the technical field of constructing and planting slope greening lawns of highways, railways, river banks, etc. The constructing and planting method solves the problems of yellowing of singly sowing warm-season lawn grass in winter, wilt of singly sowing cool-season lawn grass in summer, unaesthetic formed lawns, low efficiency, high cost and low survival rate of manual laying greensward of lawns constructed and planted in southern warm and moist zones. The constructing and planting method is characterized in that cool-season and warm-season lawn grass are sown in a mixing mode to make the lawns perennially green; supplementary material selects water retention agents of high-tech achievement for preserving moisture and fertility; cover material uses paper pulp or rice straws or straws so as to changing wastes into valuables; coloring agents are added to greatly improve the uniformity in spray; and nonwoven fabric is covered after the spray for favorable germination and growth and to prevent grass-seeds, soil and fertilizer from flushing by rain. The constructing and planting method has the advantages of high laying speed, low cost and quick lawn formation. One-time accomplishment of hydraulic grass seed spraying and sowing, fertilization, coverage and watering is used, and the formed lawns are uniform and beautiful.

Description

The planting and establishing method on slope of highway lawn, south

Technical field:

The invention belongs to the technical field on the green lawn of side slope plantings such as highway, railway, river levee.

Background technology:

Most of area, China south belongs to the warm moist area, soil is faintly acid, annual rainfall concentrates on two seasons of spring and summer greatly, summer temp height and longer duration, winter temperature is low, be unfavorable for so very much the growth of turfgrass, the jaundice in winter of clean culture warm season turf, the clean culture cold-season turfgrass is withered summer, thereby the lawn utmost point that forms is not attractive in appearance, has employing cold in the past, warm two seasons type grass mixed seeding, also excessive because of the grass seeds consumption, or it is unreasonable to arrange in pairs or groups, and can not guarantee that pastures of plenty throughout the year, for solving this difficult problem, through experiment repeatedly for many years, research sums up a cover and is applicable to that the place in southern china warm moist area is at highway, railway, the technical method of side slope lawn plantings such as river levee.

Summary of the invention:

The objective of the invention is the green lawn of planting on the side slope of China's south highway, railway, river levee.The objective of the invention is to realize by following approach: 1, domatic cleaning: with the domatic discarded object of going up, weeds are cleaned out.2, domatic surface treatment: that will clean out domaticly ditches again, lays table soil or linked network, lays the native surface treatment of table.3, select the period of sowing grass seeds by duster; Annual 3 to September.4, lawn grass variety seed consumption is selected: the warm season turf weight percentage accounts for 69%, wherein, every square metre 4 gram of Bermuda grass, every square metre 5 gram of paspalum notatum, every square metre 2 gram of weeping love grass, the cold-season turfgrass weight percentage accounts for 31%, wherein every square metre 2 gram of Bai Sanye, every square metre 3 gram of Festuca Arundinacea.5, grass seeds weighing: calculated the weight of required 5 kinds of grass seeds and weighing is good respectively by area on the spot.6, grass seeds vernalization is handled: paspalum notatum, Bai Sanye is by the method vernalization of warm-cold seed treatment, other grass seeds are pressed the method vernalization of normal temperature seed soaking, 7, auxiliary material kind consumption is selected: every square metre of 150-200 gram of composite fertilizer, every square metre 150 gram of mulch paper pulp or straw or straw, light green every square metre 1 gram of colouring agent, every square metre 5 gram of adhesive carboxymethyl cellulose or sodium carboxymethylcellulose, every square metre 6 gram of water-loss reducer Sodium Polyacrylate or polyacrylate or starch graft acrylic acid, 3.5 kilograms every square metre in water, 8, auxiliary material weighing: calculate by area on the spot, weigh up the weight of various auxiliary materials.9, broken auxiliary material: the broken auxiliary material that needs fragmentation.10, all grass seeds and auxiliary material all add stirring in the spray seeder.11, fluid power is sowed grass seeds by duster: after treating that mixing material stirs in the spray seeder, through hydraulic pump, shower nozzle evenly be sprayed at domatic on.12, cover nonwoven: that will spray is domatic with 10-15 gram/m ²Nonwoven covers, and nonwoven is fixing with bamboo nail or iron wire nail, and 13, take off cloth and practice seedling: after treating that the turfgrass seed germinates, careless seedling is long to be taken nonwoven off behind the 6-8cm height, and careless seedling is being grown under normal environment and temperature condition.14, form the lawn.Advantage of the present invention is that speed of application is fast, and cost is low, the one-tenth level ground is fast.Adopt fluid power of sowing seeds of sowing grass seeds by duster, apply fertilizer, cover, water and once finish, thereby the lawn that evenly forms of sowing grass seeds by duster is evenly attractive in appearance.

Description of drawings:

Fig. 1 is a process schematic representation of the present invention.

Embodiment:

Now 1 the present invention is described in further detail in conjunction with the accompanying drawings: after load weighted 5 kinds of turfgrass seeds are made germination treatment, Po Sui auxiliary material and water add in the spray seeder and stir into mixing material, then through hydraulic pump high pressure on the spray seeder be sprayed at do domatic surface-treated domatic on, cover again and do not have imitative cloth, and with the fixing nonwoven of bamboo nail or iron wire nail, make it produce greenhouse effect and prevent that turfgrass seed, clay fertilizer are by the rainwater washout.After treating seed sprouting, careless seedling grows to the 6-8cm height, takes nonwoven again off, and careless seedling is grown under normal environment and temperature condition, has promptly formed green slope protecting grassplot attractive in appearance.
