Description
Technical field
The present invention relates to ecological vegetation repair process soil improvement method, specifically a kind of raising sandbank band soil is protected
Aqueous method.
Background technology
18000 kilometers of China coastline overall length, generally using Qiantangjiang River Mouth as boundary, north is based on argillo arenaceous seashore, individually
It is regional such as Liaodong Peninsula rocky coast.Hebei province Bei Dai River, all sandbank bands in Dabu river and Luanhe River river mouth, it is prosperous
Multitude's littoral zone is dispersed with the mobility sand dune of large area, causes these regional vegetation coverage rates low (30% or so), ecoscape
Difference, it is extremely inadaptable with socio-economic development level.As " Ecological Civilization Construction " is included in national development strategy, these area ecologies
Construction faces challenge.
Since sandbank band permeability is extremely strong, (such as Dabu estuary coast band soil permeability coefficient averagely reaches 3.74m/
D), water conservation is difficult, and the difficulty for establishing vegetation is larger.So how to improve sandbank band water retention becomes vegetation repair
The key of success.
Invention content
The reality that the present invention is extremely strong with permeability for sandbank, water conservation is difficult, provides a kind of raising soil water-retaining
The method of property.
The present invention solve its technical problem the technical solution adopted is that：
A method of sandbank is improved with water retention, is carried out as follows：
(1) transplant shrub, before plant, plant plot first apply 7.0~21.0 ton/mu of turf, water-retaining agent 106~
212kg/ mus, with large excavator and 0~50cm sandy soil layer mixings, then transplant shrub；
(2) transplant arbor, plant plot dig plant pit, 1.0 meters of plant pit depth, 0.6~0.8m of length and width, with turf 11~
33kg, 0.2~0.3kg of water-retaining agent backfill half after being mixed thoroughly with the plant pit soil dug out, backfill remaining half after planting trees again.
Using the present invention of above-mentioned technical proposal, compared with prior art, advantageous effect is：
Turf and water-retaining agent all have the effect for increasing sand water holding capacity, if single use turf, cost increase
Add 3 times or more；And single use water-retaining agent, it is too big due to the use of measuring, it is easily formed after dehydration hardened.Both of the invention combine makes
With reducing cost, and overcome dehydration hardened phenomenon.By the present invention, infiltration coefficient is reduced to 1.26m/ by 3.74m/d
D reduces by 2.75 times, and effect is extremely notable；5 days can be extended by pouring water spacer, and water-saving 20% or more；Plant percent reach 95% with
On.
Below according to the maximum water-holding capacity of turf and sandy soil, different amounts of turf and water-retaining agent are added in sand
Test result, illustrate beneficial effects of the present invention.
1, the experiment of different proportion turf is added
Maximum water-holding capacity measurement is carried out to turf used and Bei Dai River new district river mouths great Pu sandy soil, as a result the maximum of turf is held
Water is 140%, the maximum water-holding capacity 36.84%~45.26% of sandy soil.
Different proportion turf water-holding capacity (%) variation tendency table is added in 1 sandy soil of table
As can be seen from Table 1, with the increase of turf ratio, water-holding capacity increases, but very to increasing degree when 5%
It is small.
Variance analysis is carried out to 1 data of table, data are included in table 2.
2 analysis of variance table of table
As can be seen from Table 2, difference is not notable between repeating, and significant difference between handling.
3 multiple analysis significance test table of table
Water-holding capacity reaches notable water with the difference compareed after 1% turf is added it can be seen from 3 analysis result of table
It is flat, reach the pole level of signifiance with compareing when being added 4%, but difference is not notable between 3%, 4%, 5%.Therefore deduce that knot
By, in order to improve water-retaining property of the sandbank with soil, 1% turf should at least be added, from economic considerations, at most addition
3%.
2, using water-retaining agent effect test
Water-retaining agent uses Shijiazhuang Jianyuan Starch Derivative Co., Ltd.'s product.
(1) sandbank band sandy soil apply Water retention after water-retaining agent
4 water-retaining agent of table tests determining soil moisture result table (water content %)
The average value of 4 data of analytical table can be seen that the processing using water-retaining agent, and the soil in each horizontal, each period contains
Water is above control.5 are applied in water-retaining agent level, apply the aqueous highest that 40g handles each period with every basin, level is handled with this
With compare, it is average relatively to compare high 6.40 percentage points (or 26.29%).
(2) sandbank band sandy soil apply water-retaining agent lotus certain herbaceous plants with big flowers growing way situation
5 lotus certain herbaceous plants with big flowers increment inventory table (plant height of table：cm)
Interval investigation in 5 days is primary, in order to keep table more succinct, the 10 days data in interval is taken to be analyzed, listed in table
Initial data is the average value per 4 plants of basin.
As can be seen from Table 5, it is maximum that the average plant height increment of 20g processing is applied per basin, is 5.95cm.
Comprehensive analysis moisture and plant height increment, it is 20~40g (equivalent to apply per acre that suitable water-retaining agent dosage is applied per basin
106~212kg), it is mixed into 0~50cm soil layers.
