Description
Technical field
This utility model is related to a kind of technical field of soil improvement, especially relates to a kind of alkaline land soil that is used for and improves
Planting unit.
Background technology
Salt-soda soil refers to that the reason soil that soil contains excess soluble salt, saline Land is due to soil and ground
Lower water saliferous is too high, and under strong surface evaporation acts on, underground shallow layer water is transported to earth's surface through capillary tube and is evaporated, capillary
Pipe, to during earth's surface water delivery, also takes earth's surface to the salinity in water, and after water is evaporated, soil salt passes through capillarity
Rise and accumulate in upper soll layer, salinity has been left in earth's surface and ground thin solum, so the salinity of accumulation is many, does not have again
There is enough fresh water to dilute and drained, be the formation of the salinization of soil.Salt-soda soil more than 0.3% for the saline and alkaline is because contain
Salt amount is big, or idle, or being utilized reluctantly, its yield is also very low, and economic benefit is bad.
Existing saline and alkaline modification method carries out salt-soda soil by arranging the measures such as alkali, big hydraulic pressure alkali, raised fields row's alkali using bright ditch
Improvement, these method one side quantities are larger, relatively costly, and on the other hand the salt and alkali component in underground enrichment easily gradually returns
Return surface, bad impact can be caused to the plant of surface grafting again.
There is a substantial amounts of all kinds of salt-soda soil in China, reasonable development and utilize this land resource of salt-soda soil, become inferior position resource into
Superior resources, not only significant to guaranteeing national food security, also significant to ecological environmental protection.
Accordingly, it would be desirable to a kind of planting unit being applied to alkaline land soil improvement of exploitation, overcome prior art in salt-soda soil
Inconvenience and defect present on soil improvement, to assist the plant growing of plantation on improvement salt-soda soil, reach permanent improvement saline and alkaline
The purpose of ground soil quality.
Content of the invention
In order to solve the problems referred to above of prior art presence, this utility model provides a kind of alkaline land soil that is used for and improves
Planting unit, rational in infrastructure, easy to operate, the plant for obtaining on salt-soda soil plantation after improvement provides preferable soil ring
Border, suitable plant growing, improved effect is stable.
For achieving the above object and reach technique effect, this utility model provides following technical scheme:
A kind of planting unit for alkaline land soil improvement, including plantation soil layer, soil improvement structure and water-retention canal.Institute
The soil improvement structure stated includes nutrient matrix layer, crushing straw basic unit, sand filter blanket and membrane layer from top to bottom.

Enter water-retention canal.
Nutrient matrix layer in soil improvement structure contains fertile soil and organic fertilizer, provides nutrition to become for plant growing
Point, promote growth and development of plants, improve plant survival rate.
Crushing straw basic unit of the present utility model, be through mistake special equipment stalk crasher by rice straw, Wheat Straw,
It is layered on the improving straw mulching basic unit of sand filter blanket after the agricultural wastes pulverization process such as corn straw.Powder is set in soil improvement structure
, there are soil moisture conservation and regulation device humiture in crushing straw basic unit, and crushing straw basic unit can decrease plantation dress in the dry spell
Put the ground surface evaporating capacity of interior water, maintain reservoir storage, then can buffer the erosion to sand filter blanket and membrane layer for the rainwater in rainy season.
Sand filter blanket is made up of coarse sand and rubble, plays the role of to adsorb saline and alkaline and heavy metal.Sand filter blanket has insulation, resists
Alkali is excellent, water absorption rate is low and the many merits such as excellent in durability.Coarse sand density is little, internal porous, light weight, shape
State, composition are more uniform, have certain intensity and robustness, also have the multifunctional characteristics such as good insulating.
Membrane layer of the present utility model is impermeable membrane layer, and the growth district in bottom salt-soda soil and plant is kept apart,
Salt affected soil is prevented to be combined with planting soil, it is to avoid accumulation of salt in the surface soil alkali phenomenon, beneficial to plant growing.
Sand filter blanket has draining salt discharging pipe.To lead through draining salt discharging pipe when the saline-alkali water of sand filter blanket accumulates a certain amount of
Enter water-retention canal, realize the effect of soil salt discharge desalination.
Based on above-mentioned technical scheme, the beneficial effects of the utility model are:
(1) alkaline land soil improvement and plant growing are combined by this utility model, using plantation soil layer, soil improvement
Structure and the structural features of water-retention canal, realize the comprehensive improvement of alkaline land soil, can effectively prevent accumulation of salt in the surface soil alkali phenomenon, improve and plant
Thing survival rate, promotes the ecological protection in saline and alkaline plot.
(2) planting unit of the present utility model is rational in infrastructure, easy to operate, and solving salt-soda soil cannot the asking of planting plants
Topic, compared with prior art, greatly reducing required water resource, thus effectively having saved production cost, and soil being changed
Good effect is good, high efficiency improves desalinization of soil by flooding or leaching effect.
