Description
Technical field
The invention belongs to agriculture field, more particularly to a kind of soil conditioner of salt-soda soil facilities vegetable irrigation with saline water.
Background technology
The development of coastal area industrialized agriculture is very fast, but the factor such as freshwater resources shortage, soil salinization is serious
Have influence on the economic well-being of workers and staff of industrialized agriculture.Coastal installation agricultural is mainly vegetables, flowers, production of fruit trees, particularly vegetables and produced
Water consumption is very big.The long-term underground fresh-water resource that relies on has threatened ecological safety, and at present, excess exploitation deep fresh groundwater is
Through forming cone of groundwater more.The utilization of the unconventional water resource such as salt water or recirculated water is to alleviate freshwater resources to lack, press down
One of feasible way that cone of groundwater processed further expands.Though coastal area underground brackish water, salt water aboundresources, are housed in
Shallow-layer, but water quality inferiority.Deeper degree of mineralization of ground water 2.0g/L of such as Binhai New Area in Tianjin or so, contains soda in water
Salt, sodium ion accounts for 65%~85%, pH8.0~8.6 of cation total amount, and high person is up to more than 9.0；Shallow salt groundwater and brackish water
Salinity 5g/L~20g/L, underground water chlorion accounts for anion total amount 80%~95%, sodium ion account for cation total amount 70%~
80%.Directly irrigated using brackish water or salt water, salinity can be caused poly- in upper soll layer and each lamination of the soil body, and make soil
Salinization of soil, further results in the deterioration of soil physical chemistry character.For example, soil granular structure is poor, soil hardening, infiltration coefficient
Low, infiltration is difficult, and aeration is poor, and soil pH is high, and soil salt content is high and salt ion constitutes unreasonable, sodium ion, chlorine from
Son is higher year by year.The competition of excessive sodium ion, reduces absorption of the plant to potassium, phosphorus and other nutrients, the transfer of phosphorus
Also it can be suppressed, so as to influence the nutrition condition of plant.Arid season, topsoil salinity excess accumulation, excessive solubility
Salt, causes the physiological drought of plant, easily arid is withered for plant；Salinity excess accumulation in plant tissue, can make plasm by
Evil, protein biosynthesis block, nitrogenous mesostate accumulation causes cytotoxic etc..The height suppression of soil chloride ion content
Plant growth processed, particularly reduces the commercialization partial quality and economic value of plant.Therefore, it must be taken measures using salt water
Salt is to soil, the influence of crop in reduction salt water.
Salt-soda soil facilities vegetable saltwater utilization measure will consider soil under the facility condition of salt-soda soil, miniclimate, vegetables life
The factors such as length, water feature.Temperature in Greenhouse is high, evaporation capacity is big, is unfavorable for soil salt to deep percolation, vegetables make for shallow root
Thing, the typically soil horizon in 30cm.
The country reduction soil salt accumulation methods and techniques be summed up approximately as：(1) it is physically improved.Level land,
Deep ploughing is suned the earth which has been ploughed up, loosened the soil in time, raising landform, microcell and improve the soil.(2) water conservancy is improved.Fill deploying set, storage fresh water on saline-alkali land for leaching, washing salinity by irrigation,
Lower salt discharge.(3) chemical modifying.Gypsum, ardealite, calcium superphosphate, humic acid, peat, fermentation acid-sludge etc..(4) biological modification.Kind
Planting paddy rice, plantation salt-tolerant plant field mountain valley with clumps of trees and bamboo etc., use microbial-bacterial fertilizer etc..At present, the soil improvement of soil salinization chemical harnessing
Agent is more, such as gypsum, calcium sulfate, calcium superphosphate, trade waste ardealite, industrial waste acid, organic fertilizer, detritus acid, flyash,
Peat, fermentation acid-sludge etc., these achieve certain effect to improvement salt-soda soil, and the more commonly used is organic fertilizer, gypsum, its
Middle gypsum is with Ca2+Replace Na+And be able to improve salt-soda soil with acid neutralization alkali.
But, above-mentioned chemical improvement agent is mainly used in the crops such as the wheat, corn, cotton in crop field, as dedicated for
Salt-soda soil facilities vegetable, the soil conditioner of particularly irrigation with saline water facilities vegetable have no report.

Sour calcium, more than 90%, the ardealite source desulfurated plaster that the present invention is used is purchased from Tianjin detergents and cosmetic auxiliary reagent factory.
Acid-sludge is purchased from Tianjin Tian Li DULIU vinegars limited company.
Consider that soil moisture is easily evaporated in the facility of salt-soda soil, therefore, the soil conditioner of the application will reduce evaporation and steam
Rise；Simultaneously as irrigation with saline water easily causes increasing for sodium ion and chlorion, therefore, the soil conditioner of the application will be reduced
The salt irrigated in salt water reduces sodium ion and chlorion chemical composition in soil alkali and soil in the accumulation of root layer soil, due to
The salt content in salt-soda soil is higher, antagonism and the nutrient absorption for suppressing crop, therefore, the soil conditioner of the application will improve vegetables
Salt resistance ability, enhancing vegetable nutrient absorbability is to reduce the nutrition inhibition because of irrigation with saline water.
With reference to specific embodiment, the present invention is further illustrated.

The tomato best fruiting period adopts the 2nd fringe fruit sample, is chemically examined, as a result such as table 7.As can be seen from Table 7, using soil of the invention
The relatively control raising 7.31%~14.13% of the tomato Vitamin C content of earth conditioner, total Soluble Sugar raising 1.56%~
5.47%, titratable acid improves 1.29%~2.91%, nitrate content reduction by 4.31%~10.98%.Output increased
7.41%~12.56%, 1 hectare of volume increase 6382.6kg~10823.3kg.Tomato is improved using the soil conditioner of the present invention
The effect of yield.
Table 7, using after soil conditioner to irrigation with saline water tomato production and the impact effect of the index of quality
A kind of soil conditioner of salt-soda soil facilities vegetable irrigation with saline water of the present invention can promote soil salt, particularly
Sodium ion (Na+), chlorion (CI-) infiltrated with irrigation water (brackish water, salt water) or the discharge root layer soil or soil body, absorption is oozed in side
It is fixed, accumulation of the salinity in soil is reduced, harmful ion proportion, free state concentration is reduced；With original soil mineral
Soil particle is gradually formed with chemical composition, compound microaggregate is formed with the coastal region alkaline land soil clay of viscous weight, changes
Kind soil physics structure and soil fertility etc., reach the purpose of the abundant saline groundwater of long-term, safe utilization or brackish water resource.
