Description
Technical field
The present invention relates to alkaline land improving technical fields, and in particular to a kind of side using pionner improvement salt-soda soil
Method.
Background technique
With economic continuous development, China's energy shortages contradiction is very sharp, and biomass energy development must ensure
The premise of " grain security "；The development and utilization of Coastal beach salt-soda soil can provide food source, and become the Important Economics such as the energy
The production carrier of plant；But salt-soda soil causes most plants that can not give birth to since salt content is high, retain water and nutrients ability is poor
Long, especially salt-soda soil, utilization rate and economic value are all relatively low.
Pionner has extremely indomitable vitality, can give birth under conditions of soil nutrient elements deficiency etc. is severe
Long, for salt-soda soil, vitality is more general, and plant is also stronger；But using pionner improve salt-soda soil and obtain compared with
The research of good effect is less.
In summary, the prior art there will naturally be shortcoming in practical applications, it is necessary to be improved.
Summary of the invention
In view of the above technical defects, the purpose of the present invention is to provide a kind of sides using pionner improvement salt-soda soil

Mentioning " planting method planted.
The invention has the benefit that
1, the present invention improves salt-soda soil with modifying agent, and simple process, technical requirements are low, are able to carry out large-scale popularization；
And modifying agent proportion is rationally, has to raising salt-soda soil desalinization of soil by flooding or leaching speed, increase soil water permeability, inhibition soil urease liveness fine
Facilitation.
2, after being improved using modification method of the invention to salt-soda soil, N-P-K content is mentioned in alkaline land soil
Height, pH, conductivity and basicity reduce.
3, pionner is planted on salt-soda soil, and the utilization rate in salt-soda soil is improved while this is come to your salt-soda soil, is mentioned
The high economic value of pionner.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, to this
Invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not
For limiting the present invention.
The present invention provides a kind of methods using pionner improvement salt-soda soil, include the following steps:
S1 turns over selected salt-soda soil, and ploughed depth is 45~70cm；Modifying agent ardealite and boric acid are mixed
It after conjunction, is sprinkling upon above the salt-soda soil after turning over, is then uniformly mixed, kept for 5~20 days, obtain coagulation soil.
Modifying agent sustained-release adhesive, humic acid, CMC (sodium carboxymethylcellulose), boiling are added into coagulation soil by S2
Then mountain flour is uniformly mixed, kept for 20~30 days, obtains improvement soil.
It improves in soil, the content of each ingredient of modifying agent are as follows: 40~50 parts of ardealite, 20~26 parts of boric acid, sustained release bonding
10~15 parts of agent, 8~15 parts of humic acid, 2~8 parts of CMC, 1~6 part of zeolite powder.
Ardealite and the aobvious acidity of boric acid, can neutralize with the salt-soda soil of aobvious alkalinity, the pH value in salt-soda soil can be effectively reduced；
Soil urease can promote the hydrolysis of urea ammonification in soil, be lost the urea in alkaline land soil, boric acid is to urease activity
There is good inhibiting effect, the hydrolysis rate of urea in the soil can be delayed, reduce the loss of nitrogen.
Calcium ion contained in ardealite can be chemically reacted with carbonate in salt-soda soil and bicarbonate radical, generate carbon
Sour calcium and calcium bicarbonate, wherein calcium carbonate is not soluble in water, and calcium bicarbonate is slightly soluble in water, and the property of calcium carbonate and calcium bicarbonate can be with
Promote Zinc fractions spherulitic texture, spherulitic texture can promote desalinization of soil by flooding or leaching speed with wrapping portion sodium ion, while reduce soil appearance
Weight increases soil water permeability.
Sustained-release adhesive itself is slow-release fertilizer, and the product after decomposing can provide nitrogen for plant, not will cause soil
The secondary pollution of earth；Sustained-release adhesive is line-like structures, and with binder effect, ardealite, which is reacted with salt-soda soil, to be formed
Spherulitic texture, after adding sustained-release adhesive, sustained-release adhesive can promote the formation of spherulitic texture, while sustained-release adhesive can
With the vacancy position filled up in the spherulitic texture that calcium carbonate and calcium bicarbonate are formed, so that the inside and outside portion of spherulitic texture is relatively isolated from,
The sodium ion of mobility in soil is reduced, desalinization of soil by flooding or leaching speed is promoted；Sustained-release adhesive can be slow at temperature and microbial action
It decomposes, when decomposition, organic salt can be formed with cations such as sodium, calcium in soil, the solubility of organic salt is low, reduces soil
The cations such as sodium, the calcium of free state.
Turfy soil humic acid and weathering enzyme humic acid all have good inhibiting effect to the urease activity in soil, can
The effect of volume increase, synergy is set up to alkaline land soil plantation.
CMC has good adhesive property, promotes sustained-release adhesive rapid curing, spherulitic texture can be promoted quickly to be formed.
Zeolite powder can be good at adsorbing various macromoleculars and ion, be good additive.
Mound shape is suitably raised into according to level of ground water and saline and alkaline degree in the ground for improveing soil by S3；It is risen along mound slope gesture
20~40cm of ridge, the range of grade on ridge are 15~45 degree, several fish-scale pits are built on ridge according to pionner size；Each
The bottom in fish-scale pit applies the mixture of 4.0~8.0kg turfy soil and extruding excrement, turfy soil and extruding excrement in mixture
Weight ratio is 3~5:2.It is rich in organic matter and humus in turfy soil and extruding excrement, soil physical property can be improved, increases
Soil aggregate structure keeps salt affected soil loose, and reduction salt affected soil is hardened, is conducive to water conservation, fertilizer conservation, ventilation, is conducive to plant roots
System's growth.
S4 using " three bury two step on one mention " planting method by pionner plantation into fish-scale pit；Covering improvement soil after broadcasting,
Round earth steps are formed, one layer of film with holes is covered on earth steps surface to inhibit and obstruct the infiltration of side salt water, retains and conserve soil moisture, film
Upper ridging compacting improves salt discharge efficiency in such manner, it is possible to drain in time.Inhibit plant evaporation from topsoil simultaneously, being formed is suitable for planting
The ecological environment of object survival.
Humic acid includes turfy soil humic acid and weathering enzyme humic acid.
The dosage of modifying agent is 1000~1200kg/ mus.
Pionner includes any one of salt grass, alkali wormwood artemisia, artemisia annua or Nan Juzhong.
To obtain preferred forms, the present invention is planted with above-mentioned using the method plantation pioneer in pionner improvement salt-soda soil
