Description
Technical field
The present invention relates to bank protecting methods, and in particular to a kind of semi-humid is sowed grass seeds by duster method, and environmental protection technical field is belonged to.
Background technique
Spray seeding technique is common method in modern ecological environment restoration and greening.The method of sowing grass seeds by duster of the prior art, including
Dry spray and hydraulic sowing grass seeds by duster.Dry spray refers to that providing power by air compressor machine is sprayed on work surface surface for dry shape matrix, is formed certain thick
Degree；Hydraulic sowing grass seeds by duster refers to that will sow grass seeds by duster matrix and water stir and evenly mix into mud of sowing grass seeds by duster by hydroseeder, under the action of sowing grass seeds by duster pump,
It is even to be sprayed on working face, reach certain thickness by repeatedly sowing grass seeds by duster.
It is the slope with certain angle due to needing to carry out the side slope of restoration of the ecosystem.For height height, quality is poor, makees
The limited high gradient slope of industry condition, existing dry spray or hydraulic sowing grass seeds by duster method are unable to satisfy practical application request.If using
Dry spray, the matrix such as soil by air pipeline are transported to interface of sowing grass seeds by duster after breaing up, complicated for operation, mobile inconvenience.If using
Dry spray, required personnel are more, and efficiency is extremely low (effective operation area≤300 ㎡/day), and the matrix attachment sowed grass seeds by duster is loosely, rainfall
It is easy to wash away the matrix of sowing grass seeds by duster of lower part slope surface to flow away.If using hydraulic sowing grass seeds by duster, it is difficult to once sow grass seeds by duster and reach sowing grass seeds by duster for requirement
Thickness, needs to be repeated several times construction, and efficiency reduces.Soil etc. sows grass seeds by duster material dilution in water, the thickness for material of sowing grass seeds by duster every time
No more than 10cm, efficiency is extremely low, poor continuity.More especially compared with high gradient slope, execution conditions do not allow to be repeated several times
Operation, and then hydraulic sowing grass seeds by duster is unable to satisfy the job requirements of many high gradient slopes.
Therefore, the prior art sows grass seeds by duster difficulty height to high gradient slope, it is difficult to and it disposably sows grass seeds by duster and reaches expected thickness, meanwhile, it reaches
To effect of firmly sowing grass seeds by duster.
Summary of the invention
It sows grass seeds by duster method the present invention provides a kind of semi-humid.The goal of the invention of this method is: solution high gradient slope, which is sowed grass seeds by duster, asks
Topic realizes that disposable sow grass seeds by duster reaches higher caliper；Raising is sowed grass seeds by duster efficiency；And sow grass seeds by duster material can in slope surface firm attachment.
To reach the purpose, the technical scheme is that
A kind of semi-humid is sowed grass seeds by duster method, comprising the following steps:
1, sieve soil
Sieve soil is carried out using clod-riddler, aggregate maximum gauge is 3cm.
2, material of sowing grass seeds by duster mixing:
The soil that step 1 is sieved is mixed with improved materials, is stirred evenly, is obtained material of sowing grass seeds by duster；Every cube of 3000-5000 grams of soil addition
Improved materials；
The improved materials: it is mixed by the component of following parts by weight: 3000 parts of soil improvement fiber, binder 30-80
Part, 20-30 parts of water-retaining agent, 10000-15000 parts of rice husk, 15000 parts of organic fertilizer, compound fertilizer 150-160 parts, vegetable seeds 3-5
Part, 0-45 parts of chitosan, 0-80 parts of sodium alginate mix.The soil improvement fiber: for microcellular structure, by bark, broken
Wood etc. are pyrolyzed under high-temperature and high-pressure conditions and are formed, length 1.5-2.5cm, diameter 0.05-0.15mm.The high-temperature and high-pressure conditions:
Pressure is 340-350 kPas, and temperature is 190-195 DEG C.The soil improvement fiber is a kind of recyclable plant fiber
Substance, the unique a large amount of irregular gaps of the fiber, hydrophilicity with super strength, rate of moisture absorption is fast, is not easy plate after dry
Knot, sprouts rapidly, strong sprout provides ideal growing environment for seed.The fiber can provide organic matter for soil, and improve
Water holding capacity；The wood-fibred passes through high-temperature sterilization, is free of weed seed and pathogenic bacteria.
3, it sows grass seeds by duster
It is sowed grass seeds by duster using good happy KP-25SR hydroseeder, material humidity of sowing grass seeds by duster is 25-40%；
25 m of the amount of injection3/ h, pumping pressure are 14 MPa, and vertical transport distance is 160 m, and horizontal transport distance is 650 m, point
With valve form be S pipe valve, the big partial size of aggregate be 30 mm, concrete slump 12-23 cm, rebound degree≤15%, operation dust concentration≤
10 mg/m3, concrete cylinder internal diameter × stroke: 140 × 1000 mm of Φ；Diesel engine model R4105ZD7, diesel engine power 60-
62 kw, rated speed 1400-1500 rpm, hydraulic oil container volume 300-350 L, volume of fuel tank 50-60 L, feeding height
1000-1200 mm。
Through testing, of the invention sows grass seeds by duster with a thickness of 15-30cm, and efficiency of sowing grass seeds by duster is 800-870 ㎡/day.
Compared with prior art, technical solution of the present invention has the advantages that
