Abstract
The invention discloses a kind of processing methods for significantly improving coastal saline soil physical property, including closed drainage, the laying of separation layer early period, organic materials addition and earthworm and wormcast to improve.Closed drainage: utilizing salinity solubility principle, and bellows with holes is placed into the soil, and outsourcing geotextile and non-woven fabrics prevent soil particle from blocking ripple pore；Separation layer early period is laid with: being applied to improvement early period, for interrupting soil capillarity, is inhibited deep soil salinity to shift to topsoil soils, the later period is cancelled, and insolated layer materials are dry reed and rice straw section；Organic materials addition: it is introduced to earthworm and creates good growth and nutritional condition；Earthworm and wormcast are improved: the mass ratio of control soil moisture content 20-30%, wormcast dosage and organic materials is 3:5-10.This method can be such that salinity reduces, and the soil weight reduces, and porosity increases, and the content of organic matter improves, and field capacity increases.
Description
Technical field
The present invention relates to a kind of salt affected soil processing methods, and specifically it is physical to significantly improve coastal saline soil for one kind
The processing method of matter.
Background technique
The soil salinization is a global resource problem and ecological problem.Coastal saline-alkali soil bulk density is high, porosity is small,
Soil is easy to harden, and ventilative water permeability is poor.C, the mineralization degree of N is low, and the activity of enzyme is suppressed in soil, influences the micro- life of soil
The activity of object and the conversion of organic matter.Soil nutrient utilization rate is low, and content of organic matter decline causes soil fertility poor.Soil contains
Salt amount is bigger, and soil permeability, ventilation capacity are poorer, and which has limited the developments and utilizations of coastal saline soil.
Currently, improving coastal saline soil physical property common practices is by plant measures such as afforestation or to pass through fertilising
Equal agronomic measures.These measures have certain help to soil physical properties are improved, but cannot realize reduction salinity simultaneously, reduce
The soil weight increases porosity, improves the content of organic matter, increases field capacity.
Summary of the invention
In order to improve the physical property of coastal saline soil, the object of the present invention is to provide one kind to significantly improve coastal saline-alkali
The processing method of soil physical properties, this method can be such that salinity reduces, and the soil weight reduces, and porosity increases, the content of organic matter
It improves, field capacity increases.
The purpose of the present invention is achieved through the following technical solutions:
A kind of processing method significantly improving coastal saline soil physical property, it is characterised in that method includes the following steps:
(1) closed drainage: utilizing salinity solubility principle, and bellows with holes is placed into the soil, outsourcing geotextile and nonwoven
Cloth prevents soil particle from blocking ripple pore；
(2) separation layer early period is laid with: be applied to improvement early period, for interrupting soil capillarity, inhibit deep soil salinity to
Topsoil soils transfer, later period are cancelled, and insolated layer materials are dry reed and rice straw section；
(3) organic materials adds: introducing to earthworm and creates good growth and nutritional condition, organic materials is by decomposed cow dung, corruption
Ripe chicken manure, fallen leaves, rotted plant material rhizome, stalk, elm mushroom mushroom slag according to 5-10 parts, 5-10 parts, 3-5 parts, 2-4 parts, 2-4 parts and
4-8 parts of mixing mix；
(4) earthworm and wormcast are improved: the mass ratio of control soil moisture content 20-30%, wormcast dosage and organic materials is 3:
5-10。
In the present invention, closed drainage is using salinity solubility principle, by bellows with holes according to 100 cm of depth, gradient
2 ‰, during spacing 8m places into the soil, outsourcing layer of geotextile and layer of non-woven fabric prevent soil particle from blocking ripple pore.Every
Absciss layer laying is mainly used in improvement early period, for interrupting soil capillarity, deep soil salinity is inhibited to turn to topsoil soils
It moves, the later period can be cancelled, and insolated layer materials are dry reed and rice straw section, and length is 3-4.5 cm, and the depth of burying is 40 cm.
Organic materials addition creates good growth and nutritional condition mainly for introducing to earthworm, and organic materials is by decomposed cow dung, corruption
Ripe chicken manure, fallen leaves, rotted plant material rhizome, stalk, elm mushroom mushroom slag according to 5-10 parts, 5-10 parts, 3-5 parts, 2-4 parts, 2-4 parts and
4-8 parts of mixing mix, and stack 45 days, and control moisture content is 60%, turn over every 15 days once, and addition quality compares one thousandth
Organic fertilizer fermentation agent (production of Hebi Wanyuan Biotechnology Co., Ltd).Earthworm and wormcast are added, soil moisture content is controlled
28%, the mass ratio of wormcast dosage and organic materials is 3:7, and earthworm input amount is 50 kg per acre.
After present invention application, have following obvious the utility model has the advantages that salinity reduction, the soil weight reduce, porosity increases, and has
Machine matter content improves, and field capacity increases.
Specific embodiment
A kind of processing method significantly improving coastal saline soil physical property, comprising the following steps: closed drainage；Early period
Separation layer is laid with；Organic materials addition；Earthworm and wormcast are improved.
Closed drainage is using salinity solubility principle, by bellows with holes according to 100 cm of depth, gradient 2 ‰, spacing
During 8m places into the soil, outsourcing layer of geotextile and layer of non-woven fabric prevent soil particle from blocking ripple pore.Separation layer is laid with
It is mainly used in improvement early period, for interrupting soil capillarity, inhibits deep soil salinity to shift to topsoil soils, the later period can
Cancel, insolated layer materials are dry reed and rice straw section, and length is 3-4.5 cm, and the depth of burying is 40 cm.Organic materials adds
Add mainly for being introduced to earthworm and creating good growth and nutritional condition, organic materials by decomposed cow dung, Chicken dung, fall
Leaf, rotted plant material rhizome, stalk, elm mushroom mushroom slag are mixed according to 5-10 parts, 5-10 parts, 3-5 parts, 2-4 parts, 2-4 parts and 4-8 parts
It mixes, stacks 45 days, control moisture content is 60%, and primary, the millesimal organic fertilizer hair of addition mass ratio was turned over every 15 days
Ferment agent (production of Hebi Wanyuan Biotechnology Co., Ltd).Earthworm and wormcast are added, soil moisture content 28%, wormcast are controlled
