Further, described organic fertilizer is fermentation maturity cow dung, and the particle diameter maximum of described organic fertilizer is no more than 10mm, Particle diameter<5mm's accounts for more than 80%, pH value 6.0~8.0, particle diameter EC ＜ 8mS/cm, organic matter >=500g/kg.
Further, described coconut palm chaff is that coconut palm chaff brick is expanded, desalinization of soil by flooding or leaching working process material, the grain of coconut palm chaff using compression Footpath<8mm, Cl<3000mg/L.
Further, described turf is the organic matter of bryophyte formation, and the particle diameter of described turf most very much not surpasses Cross 10mm, particle diameter<5mm turf accounts for more than 80%, the pH value 4.0~8 of described turf, the EC of described turf<2.5mS/ Carbon and the mass ratio of nitrogen are less than 25 in organic matter >=500g/kg in cm, described turf, described turf.
Further, described vermiculite is the soilless culture material that market is sold, particle diameter<2mm vermiculite account for 80% with On.
Further, described zeolite is the soilless culture material that market is sold, particle diameter<3mm zeolite account for 80% with On, specification is CEC>110.
Present invention also offers the preparation method of the above-mentioned lightweight water-retaining type matrix that roof greening is reconstructed suitable for low load, Comprise the following steps：
S1：The coconut palm chaff brick water drenching desalinization of soil by flooding or leaching will be compressed, passes through elution, the soaked coconut palm chaff for being completely soaked expansion, becoming moistening, expansion 5-7 times of coefficient, is air-dried after scattering to moisture content 40%~60%, takes 15~45 parts by volume；
S2：Cow dung after being handled through compost maturity, is crushed to particle diameter<5mm, moisture content 25%~45% takes 12~30 bodies Product part；
S3：Turf is crushed, the particle diameter maximum of described turf is no more than 10mm, particle diameter<5mm turf account for 80% with On, the pH value 4.0~8 of described turf, the EC of described turf<Organic matter >=500g/ in 2.5mS/cm, described turf Carbon and the mass ratio of nitrogen are less than 25 in kg, described turf, and moisture content 20%~45% takes 10~30 parts by volume；
S4：Afforestation is sieved with vermiculite, particle diameter<2mm vermiculite accounts for more than 80%, takes 15~35 parts；
S5：Choose zeolite, particle diameter<3mm zeolite accounts for more than 80%, and specification is CEC>110, take 10~35 parts by volume；
S6：Resulting coconut palm chaff, organic fertilizer, turf and vermiculite, zeolite are sufficiently mixed as suitable for low load reconstruction The lightweight water-retaining type matrix of roof greening.
The lightweight water-retaining type matrix of the present invention is by organic fertilizer, coconut palm chaff, turf, vermiculite, zeolite of the cow dung for main fermentation Composition.The matrix has preferably drainage, water-retaining property and nutrient preserving capability, and nutrient is comprehensive, balanced, speed-slow successive.The present invention's Raw material drawing is convenient, and turns waste into wealth, and substrate products are adapted to city low load roof greening, to promoting urban ecological environment matter Amount lifting has positive role, can produce good economy, society and environmental benefit.
The present invention is compared with prior art, and its technological progress is positive and obvious.The present invention is with agro-industry discarded object For primary raw material, by the inorganic material and organic material of different-grain diameter by rational proportion, low load roof is not only met Planting technique requirement, and reach the effect of water holding.The present invention can not only be carried on low load reconstruction roof for plant growth For enough nutrient and mineral nutrition, and by the contradiction of different material rational proportion solution unit weight and water holding, make the present invention Matrix have water retaining function concurrently while lightweight.
Brief description of the drawings：
Fig. 1 is that the loads change of common planting soil after high-intensity rainfall compares figure.
