Abstract
The invention relates to the technical field of ecological slope revegetation, and particularly to a spraying material for slope revegetation. The spraying material is produced by the following steps: a. producing 80 mesh attapulgite powder; b. producing 80 mesh mineral ecological organic fertilizer powder; c. processing polyvinyl alcohol into liquid polyvinyl alcohol in a reactor: adding water into the reactor and heating the water to 78 to 80 DEG C, adding polyvinyl alcohol, the amount of which is 8 to 10% of that of the water in the reactor, into the reactor, keep heating the mixture to 95 to 98 DEG C while stirring at the same time, stirring for 2 to 2.5 hours while the temperature is maintained between 95 and 98 DEG C, and then cooling naturally to 50 DEG C to obtain the liquid polyvinyl alcohol; d. obtaining mixed material by evenly mixing, by weight, 65 to 70 parts of the attapulgite powder, 33 to 28 parts of the mineral ecological organic fertilizer powder and 2 parts of a mineral water retainer; and e. obtaining the spraying material by using a disc pelletizer to produce phi 1 mm to 1.5 mm pellets from, by weight, 92 to 95 parts of the mixed material and 8 to 5 parts of the liquid polyvinyl alcohol. The price of the spraying material is only two thirds of those of conventional materials.
Description
Technical field
The invention belongs to ecological revetment greening technique field, be specifically related to a kind of greening side slope material of sowing grass seeds by duster.
Background technology
Along with the fast development of economic society, the fundamental construction speed of China is accelerated, and because implementing the construction projects such as traffic, water conservancy, mine and electric power, has formed a large amount of bare slopes.These bare slopes have not only affected Landscape Ecological, and also there is geologic hazard hidden danger in some, affect the safety and stability of main construction.Therefore, a lot of local Efforts To Develop greening side slopes that start.
The environment protection significance of greening side slope is fairly obvious, and greening side slope can be beautified the environment, and water conservation prevents erosion and comes down, and purifies air.Especially for rock matter side slope, the environment protection significance of greening side slope is more outstanding.Rock matter side slope is different from soil-slope, does not possess the needed soil of plant-growth and nutrient, and water retaining function is poor.
It is technology commonly used that greening side slope is sowed grass seeds by duster, and adds that seed sprays after generally adopting vegetable mould, straw fiber, tackiness agent, water-holding agent and chemical fertilizer to stir, and effect is general, and poor stability, the plant survival rate of greening side slope is low, cost is higher.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of cost is low, plant survival rate is high, greening is stable
In order to solve the problems of the technologies described above, the technical scheme that the present invention takes is as follows: a kind of greening side slope material of sowing grass seeds by duster, it is characterized in that: take Attapulgite Clay Minerals, mineral ecological organic fertilier particle, polyvinyl alcohol and 80 order mineral water-holding agents is raw material, makes according to the following steps:
A, Attapulgite Clay Minerals is pulverized, crossed 80 mesh sieves, make attapulgite;
B, mineral ecological organic fertilier particle is pulverized, crossed 80 mesh sieves, make mineral ecological organic fertilier powder;
C, polyvinyl alcohol are processed into polyvinyl alcohol liquid at reactor, fabrication process condition: to the reactor water filling, be heated to 78～80 ℃; Add polyvinyl alcohol in reactor, 8%～10% of the weight that add-on is water in still;
Continue to be heated to 95～98 ℃, heat while stirring, under 95～98 ℃ of heat-retaining conditions, stir 2～2.5 hours; Then naturally cool to 50 ℃ and obtain polyvinyl alcohol liquid, tinning is standby;
D, be 33～28 parts of 65～70 parts of attapulgites, mineral ecological organic fertilier powder and the proportioning of 2 parts of 80 order mineral water-holding agents by weight, even in stirrer for mixing, obtain batch mixing;
E, be 92～95 parts of batch mixings and the ratio of 8～5 parts of polyvinyl alcohol liquid by weight, with granulating disc, make Φ 1mm～1.5mm particle, obtain the greening side slope material of sowing grass seeds by duster.
Mineral ecological organic fertilier particle in raw material and 80 order mineral water-holding agents are obtained by commercial sources, mineral ecological organic fertilier particle is that the glad celebrating environmental protection in Gansu science and technology limited Company is produced " glad celebrating board " mineral ecological organic fertilier, and 80 order mineral water-holding agents are that the glad celebrating environmental protection in Gansu science and technology limited Company is produced " glad celebrating board " 80 order mineral water-holding agents.
Apply the technique of sowing grass seeds by duster of the present invention: be that greening side slope is sowed grass seeds by duster material according to the weight part proportioning of 3～5:100 by the seed after vernalization and the present invention, after stirring, evenly be ejected into the side slope surface, thickness is 2～3cm, trickle after spray.
The present invention has adopted attapulgite and other to be of value to the material of plant growth, with polyvinyl alcohol, makees tackiness agent.Guaranteed that through experiment the stability of greening side slope and surviving rate all reach more than 95%.These product are easy to use at the scene, and price only has 2/3 of traditional material.Attapulgite in raw material of the present invention has good slow release effect, water conservation, fertilizer conservation, preserves soil moisture, prevents erosion, and builds good plant growing condition, improves the ecological environment.
