Description
Technical field
The present invention relates to a kind of beach salty soil modification methods improving topsoil soils nitrogen holding capabilities, belong to Agricultural Water
Native engineering field.
Background technology
Due to urban sprawl, cultivated land resource increasingly reduces, and city arable badlands potentiality are relatively small.By coastal soil and incite somebody to action
It is used for arable farming, advantageously accounts for cultivated land resource problem increasingly in short supply.However, coast saline soil is due to salt content
Height, soil physico-chemical property is poor, and needing can raise crop after improvement.Currently, the method for salt-affected soil improvement has very
It is more, but there is different degrees of limitation.Such as heavy metal pollution of soil, effect is got instant result, but palliative, and in large area strand salt
Application effect in stain soil improvement is limited by cost；Flood elution method can effectively inhibit topsoil soils salinity, but it is only
By salt leaching to relatively deep soil, strong evaporation conditions easily lead to the soil accumulation of salt in the surface soil；Directly use closed drainage method can be from basic
Soluble organic fraction in upper removal soil, but easily cause topsoil soils nutrient（N、P、K）Loss；Cladding process can be limited physically
Moisture processed brings salinity to topsoil soils, but can only also delay saliferous generation；Biological organic fertilizer is alleviating the soil salinization
Aspect significant effect can reduce topsoil soils salinity, improve the permeability of soil, reduce the soil weight, balanced soil microorganism
Fauna, but it takes effect relatively slowly, and the research of supporting technology is also very deficient, limits the popularization and application of related ends.Therefore, urgently
It needs to find a comprehensive coast saline soil improving technology, can effectively hold topsoil soils nutrient and remove soil
Salinity improves the physicochemical property of soil.

Experiment one
It is carried out in Cixi Hangzhou-Bay new district in June, 2012 ~ 2014 year December, agriculture is tolerated it in test site by Cixi City
Industry Co., Ltd provides.Experiment measures 3 soil conductivity, unit weight and available nitrogen indexs, and monitoring point is between two row hidden pipes
（A1）, right over hidden pipe（A2）And arbitrary sample point（A3）.Minute is respectively on June 15th, 2012 and December 15 in 2014
Day.Simultaneously with 50 kg/ mus of inorganic fertilizer（Hidden pipe, biological organic fertilizer, soil structure conditioner, soil conditioner and EM bacterium are not used
Agent）For control（CK）.Fig. 2 show this technology using front and back soil conductivity, unit weight and quick-acting nitrogen contents situation of change and
The comparison of itself and control treatment CK（The different letters of same year are indicated in 0.05 horizontal upper significant difference in figure（Duncan’s
multiple range test））.It is seen that after technology application, declining to a great extent occurs in topsoil soils conductivity,
A1 ~ A3 soil conductivities are substantially less than control treatment CK when off-test in 2014, show that this technology has preferably salt reduction
Effect, the wherein monitoring points A2 salinity reduce amplitude maximum, may be unobstructed due to being drained right over hidden pipe, and soluble organic fraction is easier
Drain with irrigation water.Similarly, after technology application, the unit weight of soil is on a declining curve, when off-test in 2014, A1 ~ A3 prisons
The measuring point soil weight is 1.35 ~ 1.42 g/cm3, substantially less than control treatment CK.This technology also significantly improves topsoil soils
Quick-acting nitrogen contents, when off-test, the monitoring points A1 ~ A3 Soil available nitrogen content is significantly higher than CK, wherein with the monitoring points A1 soil
Quick-acting nitrogen content amplification are maximum.In conclusion this technology, which has, reduces topsoil soils salinity, unit weight, it is quick-acting to improve topsoil soils
Nitrogen content and other effects can improve coast saline soil physicochemical property.
Experiment two
To investigate soil nitrogen holding capabilities, the pedotheque after improvement is taken（G）With control pedotheque（CK）Carry out room
Interior culture experiment, wherein the pedotheque after improvement is the equal mass mixings sample of three monitoring point samples.In two kinds of samples
Add same dose15N marks (NH4)2SO4, additive amount is 200 mg N/kg, abundance 20.15%.In control water-holding capacity 70%
In the case of dark culturing, when 2,4,6,8 and 16 d after incubation measures soil microbial biomass nitrogen and its abundance, as a result
As shown in Figure 3.It can be seen that in figure, soil microbial biomass when culture15N is there are certain fluctuation, but different cultivated days G samples
Product microbes biomass15N content is higher than CK samples, shows the coast saline soil after this technology improves, the life of nitrogen
Article holder ability is obviously reinforced.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification should all belong to the covering scope of the present invention.
