Dimension, these wood fibres can work in collusion together, increase the mechanical strength of organic mat, such as tensile strength, fracture
Intensity prevents organic breakage being covered under heavy rain washes away, while can also save resource, prevent the wasting of resources.
The centre for the organic matter covering objects system that the present invention uses is the modified hydroxypropyl methyl cellulose of porous polypropylene acid
And modified melamine cyanurate, both materials contain a large amount of carboxyl, and the salt tolerant alkalization of soil can be improved；Another party
Face sufficiently can provide nutrition for the growth of plant；The modified hydroxypropyl methyl cellulose of porous polypropylene acid is with hydroxypropyl first
Base cellulose is tie point, and polyacrylic acid is that long-chain is together in series, thus the network structure flexible formed；Modified trimerization
Cyanamide cyanurate can form big pi-conjugated structure in system, improve the mechanical strength of system, can also change with porous polypropylene acid
Property hydroxypropyl methyl cellulose formed hydrogen bond, improve the degree of cross linking of system, the water lock ability of system not only can be improved, but also make molecule
It is not easy to disconnect between chain, improves tensile strength and elongation at break, while the possibility of fire generation can also be reduced；In the two
Under collective effect, media layer damage with a certain toughness is formed, can effectively slow down hardened phenomenon, improves the use of organic covering
Time limit；And the multiple polar group in the modified hydroxypropyl methyl cellulose of porous polypropylene acid increases the water absorbing capacity of organic mat
Power can regulate and control the pore structure of size and density for the storage of moisture and provide space, and the large and small difference of structure in hole, more
Slow down the speed of moisture evaporation；Obstruction, the speed of retarding heat loss also are caused for the lost of heat simultaneously, therefore it was both
The water holding capacity of organic mat can be improved, reduce volatilization, the insulating power of system moisture, while dust also can be absorbed,
Make its reunion, reduce fugitive dust, in addition it is also possible to targetedly be regulated and controled according to the demand in place used, improved, reduces soil
The loss of earth moisture and more guarantee plant grow up strong and sturdy hot, cold snap.
The outer layer for the organic matter covering objects system that the present invention uses includes zeolite, pelelith particle and decomposing agent.Pelelith
Particle surface has positive charge, and rough surface, large specific surface area, percent opening are high, and a large amount of moisture of pelelith granular absorption covers
Fugitive dust and reentrainment of dust can be significantly reduced in lid effect and adsorption effect, and plays and prevent the soil erosion, conserves water and soil
Effect；Zeolite powder is porous material and with the socket bore on molecular level, and zeolite powder easily adsorbs a large amount of decomposing agent；And pelelith
Particle has natural cellular porous, can not only adsorb a large amount of corrosive agent, moreover it is possible to adsorbent zeolite powder；When the ornamental trees and shrubs earth's surface
Organic mat forms coating in ornamental trees and shrubs earth's surface, and corrosive agent, which is dissolved in water, to be released slowly in coating, in coating
Be not utilized again by decomposed substance, to promote the absorption of plant, the activity of edaphon can also be promoted, accelerated useless
The decomposition and release of the nutrients such as organic matter, the content of the available nutrient of soil dramatically increase in material.
It both can be improved under the modified hydroxypropyl methyl cellulose of porous polypropylene acid and zeolite, mountain stone particle synergistic effect
The heat and moisture preserving effect of machine object covering objects system；The modified hydroxypropyl methyl cellulose of porous polypropylene acid is located at zeolite and pelelith
The outer layer of particle, formation are aperture from outside to inside to the excessive of macropore, are not easy to evaporate the moisture of absorption, make can also to allow suction together
Attached corrosive agent slow release, enables soil to keep high fertility in a long time；On the other hand, porous polypropylene acid is modified
The gap formed between hydroxypropyl methyl cellulose and zeolite, mountain stone particle can provide buffering for trampling for people, to subtract
The phenomenon that light soil hardening.

Performance Evaluation
32 pottings are equally divided into two groups, referred to as improvement group and control group, are handled as follows respectively: removing improvement group basin
Weeds in cultivation are uniformly laid with the organic mat, cladding thickness 6cm.Control group is with no treatment.When covering one section
Between after, measurement improvement group compared to the soil of control group physicochemical property:
(1) inhibiting effect of the organic mat to soil moisture: wherein soil water evaporation amount is measured using weight method, fine
Under conditions of it, continuous 30 days, 5:00 every afternoon weighed the quality of flowerpot, and evaporation capacity is evaporation capacity (g/m2)=(Wn-Wn+1)/
S, wherein WnIt is the flowerpot quality (g) on the same day；Wn+1It is second day flowerpot quality (g), S is disengagement area (flowerpot cross section
Area, m2), it can determine that embodiment 1~11 and comparative example 1~5 corresponded to the soil of organic mat after 30 days, in soil
Total water evaporation quantity the results are shown in Table 1 compared to the reduction ratio of control group.
(2) soil acidity or alkalinity: the soil covered by embodiment 1~11 and the corresponding organic mat of comparative example 1~5 is weighed
The sample 10g of earth and control group air-dries soil sample by 1mm sieve pore hole and sets in 25mL beaker, distilled water 10mL is added to mix, stands
30min, with the pH value for the pH meter measurement suspension corrected.Glass electrode bulb (or bottom) is immersed into suspension mud layer when measurement
In, and the plug on calomel electrode side opening is taken out, calomel electrode is immersed in suspension upper clear supernate, reads pH value, measures embodiment
Soil acidity or alkalinity corresponding with comparative example the results are shown in Table 1 compared to the reduction ratio of control group.
(3) soil weight: cutting ring support is prevented on the cutting ring of known weight, and cutting ring inner wall, which has, slightly smears vaseline, by ring
Edge is pressed into downward vertically in embodiment soil corresponding with the organic mat of comparative example, until being full of soil in cutting ring cylinder
Only.With the soil sample repaired around native knife incision ring, the cutting ring having been filled with is taken out, cutting ring both ends are scabbled and cleaned in carefulness and outside is extra
Soil.It simultaneously at same layer sampling, is sampled with aluminium box, measures Soil Water Content.Cutting ring both ends equipped with soil sample are covered immediately,
In order to avoid moisture evaporates.Random weighing (being accurate to 0.01g), and record, it the results are shown in Table 1.
As a result it calculates: the soil weight=m/ [V (1+wm)], wherein m is wet sample quality in cutting ring；V is cutting ring volume；wmIt is
Sample moisture content (mass water content).
(4) measurement of the soil organism: being measured using potassium bichromate titrimetric method-dilution and diffusion, measurement embodiment and comparison
The corresponding soil with organic matter of example the results are shown in Table 1 compared to the increase ratio of control group.
1 test result of table
