Abstract
The invention belongs to alkaline land improving technical field, is specially a kind of salt-soda soil covering greening method, its method includes the following steps：1) french drain is dug, 2) rainwater delaying basin is built, 3) fertilising is turned over, 4) it is laid with fine-spraying belt, 5) Tree Species Selection and plantation and 6) laying plastic, salt discharge is played in the setting of wherein french drain, under every salt effect, in contrast to setting salt discharging pipe, such a mode is more economical and step is easy, flexibility higher, fertilising is carried out in alkaline land soil to turn over, contain nutrient needed for a large amount of organic matters and plant in green manure and organic fertilizer, promote Soil Microorganism growth, alkaline land soil structure can be effectively improved, increase soil fertility, in humic acid molecular structure faintly acid is made it have containing groups such as carboxyl and phenolic hydroxyl groups, therefore humic acid can neutralize the alkalescence of alkaline land soil by itself faintly acid, to adjust the acid-base value of alkaline land soil, so that the pH value balance of soil, good growing environment is provided for vegetation.
Description
Technical field
The present invention relates to alkaline land improving technical field, specific field covers greening method for a kind of salt-soda soil.
Background technology
Salt-soda soil refers to that soil is influenced be subject to nature or the factor such as artificial, causes salts substances gradually to penetrate into soil
Go, so that the saliferous and alkalinity of soil are more, and cause this kind of soil not used, China salt-soda soil substantially distributed area
Domain is in northwest, northeast, North China and coastal region, and salt-soda soil primarily forms the reason is that more work of the soil of arid area in evaporation
Under, moisture is evaporated into vapor, and is emitted into air, but the salinity in water can not be excluded and stayed among soil,
By prolonged accumulation, salinity gradually increases in soil, therefore and form salt-soda soil, by alkaline land soil institute's saliferous in itself
Point excessive, according to plant cell osmosis principle, plant cell is difficult to be absorbed to inorganic nutrient substance and moisture, causes plant
Because itself lacking inorganic nutrient substance and water and death, the vicious circle of ecology of alkali saline land is thus caused again, is covered in salt-soda soil
Greening can not only improve alkaline land soil structure, increase soil fertility and make for improving ecology of alkali saline land environment with specific aim
With, but as it was previously stated, larger in saline land greening difficulty, it is therefore desirable to design a kind of effective salt-soda soil covering greening method.
The content of the invention
It is an object of the invention to provide a kind of salt-soda soil to cover greening method, proposed in the above background technology to solve
Problem.
To achieve the above object, the present invention provides following technical solution：A kind of salt-soda soil covers greening method, its method bag
Include following steps：
1) french drain is dug：Underground Water in Salinization Area position is surveyed first, then digs french drain, french drain bottom is higher than salt-soda soil underground
0.8~1m of water level, the wide 25~35cm of french drain, rubble are inserted into french drain, rubble sub-volume is 120~140cm3, rubble
Laying depth is 28~36cm, and interlayer is laid with the sub- upper strata of rubble, and backfill soil is flushed with saline and alkaline ground；
2) rainwater delaying basin is built：1~2 rainwater delaying basin is established in salt-soda soil both sides, it is 30 that rainwater, which is detained pool size,
~50m3；
3) fertilising is turned over：The cauline leaf of green manure is first cut into 8~16cm long and then by green manure, organic fertilizer and humic acid by matter
Measure ratio 4:3:1 is applied in alkaline land soil, then carries out ploughing deeply cultivated, and ploughed depth is 22~32cm；
4) it is laid with fine-spraying belt：Fine-spraying belt is laid with growing area, fine-spraying belt arrangement spacing is 2.8~3.2m；
5) Tree Species Selection and plantation：It is 5 that Manchurian ash, diversiform-leaved poplar and American elm are pressed quantity ratio:3:1 plants in salt-soda soil, and
Regular cultivating and managing；
6) laying plastic：In fine-spraying belt top laying plastic.
Preferably, interlayer described in step 1) is polyamide fabric or polypropylene cloth.
Preferably, green manure described in step 3) is in Chinese milk vetch, sweet potato, pigeonpea, great Ye crotalaria mucronatas, sesbania and prairie milk vetch
It is one or more of.
Preferably, organic fertilizer described in step 3) is the one or more in pig manure, horsehit, sheep manure and cow dung.
The beneficial effects of the invention are as follows：A kind of salt-soda soil covers greening method, and french drain bottom can effectively be controlled higher than level of ground water
Level of ground water processed, when level of ground water rises, by french drain bottom rubble, gap is larger between rubble, in underground water
Under Radial Flow effect, underground water can flow away along french drain, will not rise, and can effectively prevent that salinity rises poly- with water level in underground water
Collect the anti-salt phenomenon that earth's surface causes soil, and the salinity of french drain top salty soil layer can be rushed using dropper and rainfall
Wash to reduce soil salt concentration, salt and alkali component can be flowed into french drain with water drains, and the sub- upper strata of rubble sets interlayer effectively to prevent
Only upper layer of soil, which is entered in rubble, blocks the phenomenon generation that gap stops blind drainage, and polyamide fabric or polypropylene cloth are acidproof
Alkalescence is stronger, and wearability is higher, and the situation for largely reducing interlayer damage occurs, and row is played in the setting of french drain
Salt, under every salt effect, in contrast to salt discharging pipe is set, such a mode is more economical and step simplicity, flexibility higher；Rainwater is stagnant
Pond is stayed to be used to store rainwater, stored rainwater is poured available for vegetation, to save water resource；Applied in alkaline land soil
Fertilizer is turned over, and containing nutrient needed for a large amount of organic matters and plant in green manure and organic fertilizer, promotes Soil Microorganism growth, can
Alkaline land soil structure is effectively improved, is increase soil fertility, is made in humic acid molecular structure containing groups such as carboxyl and phenolic hydroxyl groups
It is with faintly acid, therefore humic acid can neutralize the alkalescence of alkaline land soil by itself faintly acid, to adjust salt-soda soil
The acid-base value of soil, so that the pH value balance of soil, good growing environment is provided for vegetation, after turning over, is made saline and alkaline
The ground gas permeability of soil is strengthened, and soil Zhong Shui, fertilizer, gas and heat reach equilibrium state；Fine-spraying belt can carry out micro- spray to vegetation, set thereon
Putting mulch can make micro- spray form dropper, and mulch can both reduce soil water evaporation, and the soil moisture can be ensured by having, and be carried for vegetation growth
For suitable environment, micro- spray can save water resource, keep ground moistening not descend water too highly while reducing salt alkali concn
Position；Manchurian ash, diversiform-leaved poplar and American elm collocation plantation are selected, wherein diversiform-leaved poplar is high megaphanerophyte, and well developed root system, salt is can absorb in salt-soda soil
Alkali and salt discharge alkali but growth is more slow, Manchurian ash and American elm have Saline alkali tolerance, and growth is very fast, to ecology of alkali saline land environment elder generation
Improvement is made, while is conducive to diversiform-leaved poplar growth, after diversiform-leaved poplar adult, alkaline land soil is improved, three can be in salt-soda soil
Mutually form benign ecological cycles.
