Description
Technical field
The present invention relates to a kind of pair of beach saline land greenings to carry out the greening method after soil improvement, belongs to beach saline land
Greening field.
Background technique
Saline-alkali soil is usually the general designation to solonchak and alkaline earth, and usually 0.2% or more, basicity exists salt content in soil
15% or more, pH are 8 or more.The harm of the salinization of soil concentrates on soil and two level of plant: soil colloid structure meets with broken
It is bad, can not agglomerate and it is loose, to seriously affect ventilative, the water penetration, water conservation, nutrient preserving capability of soil, and the soil organism contains
Measure very low very limited with N, P, K fertilizer validity, leading to the decline of soil fertility, not even a blade of grass grows；In terms of plant, predominantly salt damage is existing
As, it shows as when salt, alkali composition are excessive in soil, to plant constitution moisture rib, ion rib of forcing to make peace, compels, cause physiological drought,
The normal growth and development for influencing plant, even results in the death of plant.
The modified utilization of salinized soil is general by terms of following two.First is reduced by improveing soil itself
Soil dissoluble, sodium adsorption ratio and basicity create good growing environment condition for crop；Second is that being changed using biology
It is good, i.e., by the salt-enduring cultivars selected in crop, and excavate and restrain oneself ability possessed by kind itself, directly plant later in
Salinized soil.In terms of improveing salinized soil condition, generally by physical measure, water resources industry, agronomic measures and change
Modification method etc. to be learned, in this respect, has also had accumulated many experiences abundant both at home and abroad, technology is also successfully applied,
Have received significant effect.
China has been in world's antecedent to the improvement of saline-alkali soil at present.But existing physics, chemical modifying measure are still deposited
In certain drawbacks, outstanding behaviours is to depend on hydraulic engineering measure unduly, and project inputs are big, at high cost, when regulation effect continues
Between short and bring secondary pollution problem etc..In addition, researcher worked majority in China's is for farmland and beach
The renovation and utilization of heavy salinized soil, it is relatively fewer to the research of the Greening problem of varieties in saline-alkali areas, how by farmland improvement and beach
Saline-alkali Field Control summarize the experience and improve apply to zonule greening should become later research work emphasis.
Summary of the invention
The present invention provides a kind of pair of beach saline land greenings to carry out the greening method after soil improvement, is directed to strand salt
Alkali soil characteristics proposes drainage scheme, it is determined that soil most preferably improves substrate composition, in practical field afforestation project
Have selected saline-alkali tolerant, cold-resistant, drought-enduring and with certain landscape effect tree species.
Technical solution of the present invention the following steps are included:
(1) coastal saline soil is improved: choosing mountain skin sand, corn stover, desulfurized gypsum, organic fertilizer, turf as soil improvement
Matrix, formula are+1.2% desulfurized gypsum+30kg organic fertilizer+20kg turf of+35% mountain+20% corn stover of skin sand of original soil.Original soil
Mechanical Crushing, the excessive soil block of removal partial size are carried out, and is uniformly mixed, other matrix are not processed.
(2) Tree Species Selection for Greening: when Tree Species Selection for Greening, adhering to has stronger adaptability, to cold, arid to saline and alkaline
Weather has compared with strong adaptability, artificial cultivation high survival rate, and the principle with certain landscape effect, chooses Sophora japonica L. cv. Golden Stem, state
Chinese scholartree, Chinese wax, pumila are as plant kind.
(3) field is planted: having dug depth is lm, and diameter is that the plant pit of 1.2m is several, and blind pipe conduct is buried in plant pit bottom
It pours water desalting system, the stone fragment of 10cm thickness is laid with above blind pipe, 3 plant pits of blind pipe connection are as a series.With interior soil
Column experiments are similar, and plant pit is divided into three parts when the water filling test of field, and the 10cm stone fragment that bottom is laid with is as leached layer, blind pipe
Accept plant pit series leaching liquor in exit;Middle section is 70cm as dress earthen fill zone, filling height；20cm high has been reserved above
The area of pouring water of degree.
(4) conserve: plant pit is poured water: using quantitative interval irrigation method, being watered using tap water as water source, once a day property
The tap water (l/5 for being equivalent to plant pit volume) that 200kg is poured into plant pit pours water and stops pouring water when proceeding to the 7th day, at this time
Plant pit irrigation quantity reaches 1400kg (soil ratio reaches 1.4:1).
The beneficial effects of the present invention are: (1) determined for river saline-alkali soil main physical and chemical and soil texture it is saline and alkaline
Native improved formulations；(2) technical support and engineering experience are provided for river saline land greening.
Specific embodiment
Choosing Binhai New Area in Tianjin river salt-soda soil is to implement ground, chooses mountain skin sand, corn stover, desulfurized gypsum, has
Machine fertilizer, turf be used as Soil improvement matrix, formula for+1.2% desulfurized gypsum of+35% mountain+20% corn stover of skin sand of original soil+
30kg organic fertilizer+20kg turf.Original soil carries out Mechanical Crushing, the excessive soil block of removal partial size, and is uniformly mixed, other matrix are not
It processes.Desulfurized gypsum, by ion exchange adsorption, can not only reduce the pH of soil, but also be conducive in salinized soil improvement
Plant growth is important reclamation of salinep-alkali soil material.
Having dug depth is lm, and diameter is that the plant pit of 1.2m is several, and plant pit bottom buries blind pipe and is used as desalting system of pouring water,
The stone fragment of 10 cm thickness is laid with above blind pipe, blind pipe gangs up 3 plant pits as a series.It is similar with indoor soil-column experiment, it is wild
Plant pit is divided into three parts when outer water filling test, and the 10cm stone fragment that bottom is laid with accepts tree as leached layer, blind pipe exit
Cave series leaching liquor；Middle section is 70cm as dress earthen fill zone, filling height；The area of pouring water of 20cm height has been reserved above.
Tree Species Selection for Greening is adhered to be had stronger adaptability, has cold, arid climate compared with strong adaptability to saline and alkaline,
Artificial cultivation high survival rate, and the principle with certain landscape effect choose Sophora japonica L. cv. Golden Stem, Chinese scholar tree, Chinese wax, pumila as cultivation
Plant kind.
Plant pit is poured water using quantitative interval irrigation method, is watered using tap water as water source, property is into plant pit once a day
The tap water (l/5 for being equivalent to plant pit volume) for pouring into 200kg pours water and stops pouring water when proceeding to the 7th day, and plant pit is poured water at this time
Amount reaches 1400kg (soil ratio reaches 1.4:1).
After two months, the planting survival rate of sample investigation green tree species is higher for plant greening sapling, 95% or more, originally
The soil improvement method of invention can realize quick desalination, provide the environment needed for plant grows naturally.After plant tree species 6 months,
Green tree species upgrowth situation is generally investigated, complete 1 km greening section, the green tree species survival rate of 4 kinds substantially remains in
94.5% or more, and tree species growth potential is good, demonstrates the feasible of soil improvement method and follow-up maintenance mode of the invention again
Property.Salt content and pH for plant pit soil have carried out multiple follow-up study, it was demonstrated that drainage scheme is practical, improves salt
The water soluble salt content of alkaline earth physical and chemical index related to pH etc., with the propulsion of watering and late maintaining, soil property obviously changes
It is kind, good soil environment is provided for plant survival.
