Abstract
The invention provides a hydraulic filling sea mud culture substrate, which relates to a culture substrate. The hydraulic filling sea mud culture substrate comprises the following components in parts by weight: 1 part of desalinated hydraulic filling sea mud compound substrate, 0.02-0.04 part of superphosphate, 0.044-0.091 part of organic fertilizer and 0.159-0.2 part of sludge, wherein the desalinated hydraulic filling sea mud compound substrate is an improved substrate which is formed by adding carbide slag and coarse texture materials into hydraulic filling sea mud to perform desalinating, and the volume parts ratio of the hydraulic filling sea mud, the carbide slag and the coarse texture materials is 0.5-0.65:0.01-0.5:0.25-0.5. Compared with the desalinated hydraulic filling sea mud compound substrate, the hydraulic filling sea mud culture substrate has the advantages of greatly improved physicochemical property, lowered pH value, addition of microaggregate and enhanced fertility, and can be applied to afforestation of more floristics and larger areas. By developing and taking the sludge as the main fertilizer, the invention opens up a new way to handle and utilize the sludge.
Description
Technical field
The present invention relates to a kind of cultivation matrix, particularly a kind of hydraulic filling sea mud culture substrate.
Background technology
Mushroom development along with expanding economy and urban infrastructure; requirement to land resources is urgent day by day; the saliferous hydraulic fill sea mud that dredging is come out is used for sea reclamation; become coastal cities and alleviated the effective way of land resources anxiety; simultaneously along with the increase of city's green areas and the enhancing of people's environmental protection consciousness; the greening problem in coastal cities comes into one's own day by day, and the large-area saline-alkali soil resource in coastal cities makes the land resources of its urban afforestation more nervous.Hydraulic fill sea mud is that the throwing out deposition of river alluvium in modern age salinity in seawater forms, there is not soil-forming process to take place, not natural soils, it is the soil parent material of marine solonchak, has the saltiness height, structure is poor, proportion and unit weight big, porosity and permeability coefficient are little, the clay content height, quality is sticking heavy, do not have a fertility, the characteristics such as condition that do not possess plant growing and survive are done planting technique soil if can develop hydraulic fill sea mud, just can solve the problem of the land resources anxiety of urban afforestation to a great extent, and meet sustainable development idea.
In order to make hydraulic fill sea mud be applied to afforestation, the method that adopts has by the natural precipitation desalination at present, the halophitic vegetations such as Suaeda salsa, Herba Salsolae Collinae, white thorn of growing are then improved, treating that salinity drops to is used after meeting general ornamental plant tolerance level, or carry out desalination with the mode that stirs quickening desalinations such as carbide slag, flyash, alkaline residue, thick bone material, plant corresponding floristics at the structure of the mixed-matrix after the desalination.
Though aforesaid method has solved hydraulic fill sea mud saltiness height, structure is poor, the problem that does not possess plant growing and survive, but still have the following disadvantages, by the natural precipitation desalination, and then improve by halophitic vegetation natural succession mode and to need the cycle oversize, can't adapt to the afforestation construction, Economic development and human settlement build the requirement to the time, mix carbide slag, flyash, alkaline residue, thick bone material etc. has solved the quick desalination problem of hydraulic fill sea mud, the structure of mixed-matrix also be improved significantly, but the mixed-matrix pH value after the desalination is higher, quality is based on sand grains, ventilating permeable is strong and the preserve moisture and fertility ability is lower, and the hydraulic fill sea mud organic content is low simultaneously, and fertility is barren, make so that mixed-matrix is afforested after the desalination, may cause green tree species single, species diversity lacks, the plant growing way is poor, ecological benefits are low, problems such as view dullness can't play the important breakthrough of big area greening, also can't play bigger Ecology Action.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of hydraulic filling sea mud culture substrate is provided.
The objective of the invention is to be achieved through the following technical solutions:
A kind of hydraulic filling sea mud culture substrate consists of by weight: 1 part of hydraulic fill sea mud mixed-matrix, calcium superphosphate 0.02-0.04 part, fertilizer 0.044-0.091 part, mud 0.159-0.2 part after the desalination.
Described fertilizer is at least a in cow dung, chicken manure, the pig manure.
