Abstract
The invention provides a cutting planting technology for tamarix chinensis in the dredger fill original soil area. The cutting planting technology aims to solve the greening difficult problem in the sea mud dredger fill heavy saline and alkaline area, changes the original high-invest and low-benefit greening mode, takes the ecological engineering science and the natural vegetation evolutionary changes as the guidance, and utilizes the principle of 'suitable land planted with suitable trees (plants), and suitable land with suitable method' and the salt-tolerance performance of the tamarix chinensis. The cutting planting technology adopts the method that localized amendment is conducted on the dredger fill artificially, that is, the local soil salinity is enabled to be reduced to below 2% through the permeable salt-leaching by the sand fertilizer column so that a local microenvironment suitable for root taking can be created for the cutting, and the ventilation, temperature increasing, water saving and the balance of water, air, fertilizer and the temperature can be benefited. After the growing requirement of the salt-tolerant plant like the tamarix chinensis is met, cutting is conducted. The tamarix chinensis are utilized to improve the soil after survival, reduce the soil salinity, attract the insects, birds and other animals and enable the ecological environment to be changed greatly. The cutting planting technology for the tramarix chinensis in the dredger fill original soil area is low in cost, fast in effect, sustainable and capable of providing strong technical support for the development and construction and the environmental improvement of the coastal areas.
Description
Art
The invention belongs to garden landscape Urban Greening field, especially for a kind of method of coastal land reclamation area barged-in fill original soil Urban Greening.
Background technology
Binhai New Area in Tianjin land-based area area 2270 square kilometres, the marine solonchak that wherein salt content is greater than 6g/kg accounts for 43.9% of total land area.And according to incompletely statistics, current new district barged-in fill area is more than 300 square kilometres.Land reclamation is the effective way of expansion harbour, industrial development space and town site, in recent years, coastal area is impelled to expand rapidly to shallow sea and beach area, sea reclamation is irresistible, at present, reclamation by pumping filling about the 200km2 such as PORT OF TIANJIN, Bei Tang recreation tourism district, economic zone, Nan Gang industrial area, planning the year two thousand twenty reaches 400km2, the area of marine reclamation land also will constantly increase, and barged-in fill district has become the important land resources of Binhai New District socio-economic development.
Barged-in fill (strand beach salty soil) is the new land formed by river mouth or the artificial hydraulic reclamation mode such as waterway dredging and shallow sea bed mud excavation, it is the soil parent material of marine solonchak, salt content is many at more than 10g/kg, more than pH8.0, nutrient content is low, water physics proterties is poor, does not possess the condition of garden plant growth.According to statistics, the marine solonchak that Binhai New District soil salt content is greater than 6g/kg accounts for 43.9% of total land area.
Current Coastal saline land region generally adopts mole drainage to carry out Urban Greening with " soil moved in improve the original greening " technology of changing farmland soil.The method construction cost is high, can not meet new district Urban Greening demand, and environmental destruction is serious, and " afforest a side, destroy a side " does not have sustainability.
Chinese tamarisk is the perennial woody plant of suspend Tamarix (Tamarix), and natural distribution, in China's drought in North China desert and varieties in saline-alkali areas, happiness light, drought-enduring, cold-resistant, Salt And Alkali Tolerance, also more water-fastly to wet; Chinese tamarisk secretes salt form euhalophyte, and Their Seed Germinating Period Salt-endurance is 1.0%, and the Salt-endurance of seedling growth phase is about 2%, belongs to the pioneer tree species of heavy saline district afforestation.
The present invention is directed to a greening difficult problem for the heavy RS in Alkali Region of ooze barged-in fill, change high investment in the past, poor benefit afforestation mode, with ecological engineering science and natural vegetation succession of herbaceous for instructing, " matching species with the site (plant); suitable ground legitimacy ", carry out the practical Urban Greening Mode exploration of getting twice the result with half the effort, for production unit provide clear mechanism, simple and easy to do, can the strongly salined soil Chinese tamarisk planting new technology of large scale application.
Summary of the invention
The present invention mainly utilizes the salt-tolerant trait of Chinese tamarisk, adopts the method for artificial local improving barged-in fill, namely by the permeable desalinization of soil by flooding or leaching of the fertile post of sandy soil, makes local soil salt content drop to less than 2% and meets the salt-tolerant plant growth requirements such as Chinese tamarisk.Punch according to seeding row spacing 50cm × 50cm at barged-in fill card punch, bore dia 6cm-8cm, degree of depth 15cm-20cm.In hole, inject the mixture of river sand and fertilizer, river sand and combination of organic manure are 4: 1-3: 1.Rear filling is once permeable, makes the hole salt content short time drop to less than 3%, and after the growth meeting the salt-tolerant plants such as Chinese tamarisk requires, the raw cuttings of clip 2-3, cutting length 15cm-20cm, cuttings clip is apart from terminal bud 1cm-2cm, and shearing cuttings need soak 5-7 days.Cuttings inserted in the hole of backfill river sand and fertilizer, insertion depth is the 3/5-2/3 of cutting length.Cuttage is selected in be carried out March in spring-April.This technology is that cuttings growth creates a local microenvironment being applicable to rooting, and is conducive to ventilating, heats, economizes on water and liquid manure gas heat balance.Chinese tamarisk woods is utilized to improve soil after Chinese tamarisk survives, reduce soil salt content, attract insect, birds and other animal, ecotope is made to obtain huge change, ecosystem balance and logistics, can flow, information flow progressively will enter benign cycle, for the development & construction of coastal area and enhancement of environment provide powerful Guarantee Of Environment.
Embodiment
On the south being experimental field positioned at Weier Road, economic zone, Tianjin, barged-in fill district carries out Chinese tamarisk Cutting test, this region is hydraulic reclamation Cheng Luqu, and hydraulic reclamation becomes the land time short (about about 2 years), and ground is soft, big machinery does not increase, and is difficult to carry out mechanized soil preparation and construction of improving the soil.Current earth's surface 30cm is soil layer duricrust, and 35cm-50cm is putty paste, and below 50cm is thin mud, and water content increases from top to bottom gradually, and is difficult to discharge.
In March, 2013 carries out Chinese tamarisk Cutting test at above-mentioned zone, and cuttage gets out Chinese tamarisk cuttings 500 the last week.Punch in barged-in fill district according to the seeding row spacing of design, after punching, backfill river sand in hole, waters permeable after backfill, the cuttings of about one week time of immersion is inserted and has backfilled in the hole of river sand and fertilizer.Cutting survival rate is added up to more than 85% after three months.
