Specific implementation mode
The present invention with soil salt content itself and sands improvement reduction salinity percentage using wheat salt tolerance threshold value as standard
For reference value, establishes with the fixed husky relationship of salt and choose the best alternatives；Fertilizer efficiency numerical value can be improved after application of organic fertilizers as variable,
Most critical factor is analyzed from factors, using common wheatland yield as standard, is established and is adjusted the relationship of production to select with fertilizer
Optimal case.Salt content is reduced with river sand first, salt content is reduced to as within the scope of salt-tolerant threshold, then collocation is applied
Organic fertilizer adjusts yield, realizes optimal production.
The determination of above two scheme is specially：
1, with the fixed sand of salt
(1) wheat salt tolerance threshold value determines
Wheat yield and soil salt content exist extremely significantly negatively correlated.Wheat each period, resistance to salt figure was different, and the jointing stage is small
Wheat group produces a polarization, and determines the critical period of spike number, wheat is mostly important in the growth performance of this phase, and to salinity
It coerces more sensitive period, the present invention is with the standard salt-tolerant threshold that jointing stage salt tolerance index is the present invention.
1 wheat during jointing stage salt-tolerant threshold of table.
| Variety name | It is resistant to lower limit (‰) | It is resistant to the upper limit (‰) | It is very poor | Average (‰) |
| Good star 99 | 2.02 | 2.27 | 0.25 | 2.15 |
| Mountain agriculture 20 | 2.03 | 2.32 | 0.29 | 2.18 |
| Jinan 18 | 2.32 | 2.71 | 0.39 | 2.52 |
| Jimai 22 | 2.16 | 2.29 | 0.13 | 2.23 |
| Mountain agriculture 22 | 1.86 | 2.35 | 0.49 | 2.11 |
| It is small to lay down 81 | 2.16 | 2.46 | 0.30 | 2.31 |
| Mountain agriculture 16 | 2.13 | 2.38 | 0.25 | 2.26 |
| Shore wheat No. 1 | 2.23 | 2.28 | 0.05 | 2.26 |
| Melt No. 3 in mountain | 2.24 | 2.61 | 0.37 | 2.43 |
| Moral anti-961 | 2.63 | 2.96 | 0.33 | 2.80 |
Two kinds are divided into for the selection of wheat salt tolerance threshold value, first, accurately determining method, one can be found by exactly referring to upper table
A exact value；Second is that fuzzy determine method, the maximum of the minimum value and lower limit of a upper limit is exactly gone out by the data statistics in table 1
Value determines a secure threshold range for being suitable for all wheat breeds.
(2) salt is pressed down with sand
Press down salt principle：Reinforce Infiltration Characteristics in Field Soils, reduces rainwash；The macroporous structure of sandstone has significantly blocked soil
The rising of earth capillary, cut-out or mitigation evaporation power, hinder evaporation to carry out, can substantially reduce soil water evaporation and act on, right
For evaporation, the rising of soil capillary water can be cut off in gravel, and moisture can only be spread in the form of steam state, is returned to inhibit or mitigate
Salt phenomenon occurs；The husky artificial height for increasing groundwater depth, Salt Strees Condition being inhibited to occur is sanded or mixed, ensures crop root hair
It educates, plant strain growth.Principles above is planted in the Salt movement mechanism of " salt comes with water, and salt is walked with water, and water, which desalts, to be deposited ".
The husky thickness of the different pavings (mixing) of table 2 influences the inhibition of soil salt.
After difference mixes sand amount and covers the sand processing of sand thickness, soil water evaporation produces different, causes section salinity
Distribution is in different feature.It is saliferous to be formed closely related with soil evaporation, either evaporation from phreatic water or evaporate after infiltrating
Layer of sand can significantly inhibit to evaporate, while reduce salt accumulation in surface soil effect.Mixing sand significantly inhibits soil capillary water to rise
Speed and the increment of groundwater inhibit to reinforce with the increase for mixing sand amount.With the increase mixed sand amount He cover sand thickness, surface layer
Salinity shows reduction trend, and the salinity of soil body bottom then shows increased trend.
Heavier farmland is being influenced by salination, reaches cultivated by admixing the pore structure of sand adjusting fine textured suil
The desalination purpose for making layer soil has in agricultural production and significantly improves and increase production and other effects.Sand is covered to upper soll layer 10cm, and
It is incorporated into 15cm, surface soil salinity can be significantly decreased, with the increase that gaza is measured, saturated hydraulic conductivity constantly increases, and two
Person is in extremely notable exponential relationship；Go out flow liquid conductivity and pH value to increase with grains of sand additive amount and reduce, conductivity and grains of sand addition
There are exponential function relations, conductivity maximum difference to appear in surface layer between amount, on secondary surface layer, due to sand macroporous structure, water
Point by the main evaporation loss in a gaseous form in sand interface, therefore there is higher salt content near interface.With
The increase of depth is mixed sand processing and is gradually reduced with the soil profile salt content positive difference for covering sand and handling same depth.It is attached in the soil body
Closely there is a joint, under this joint, the evaporation driving force that salinity moves up gradually weakens, and is brought by infiltrating downwards
Salt content is in increase trend.And reach arable layer by admixing the pore structure of sand adjusting fine textured suil in this area
The desalination purpose of soil.
(3) in the fixed husky determination method of salt
It is different as can be seen from Table 2 to sand the salt reduction effect that thickness is likely to be breached, then the salt content based on research soil
It may be selected by out that be achieved thickness need to be sanded with the difference of the salt-tolerant threshold of wheat.For example, salt-soda soil salt content be 2.8~
3.2 ‰, select salt tolerant High-Yield Wheat Cultivar is small to lay down 81, as can be known from Table 1, salt-tolerant threshold 2.16~2.46, select lower limit for
2.16, that is, soil salt content is not above 2.16 ‰, needs to reduce salt content 0.64~1.04 ‰, needs are found by table 2
It sands thickness and can be only achieved this salt reduction purpose in 5~7cm.
2, it is adjusted and is produced with fertilizer
(1) influence of Organic Manure on Soil physicochemical property and yield
Influence of the 3 Different Fertilization scheme of table to soil physico-chemical property and yield
(2) it is determined based on the quantifying organic manure of yield
4 soil nutrient of table improves the correlation with output increased
| Organic matter | Full nitrogen | Full phosphorus | Full potassium | Alkali-hydrolyzable nitrogen | Rapid available phosphorus | Available potassium | |
| Grain yield | 0.448 | 0.919** | 0.839* | 0.440 | 0.954** | 0.704 | -0.455 |
From table 3 it can be seen that grain yield and alkali-hydrolyzable nitrogen, full nitrogen significant difference, and it is most notable with alkali-hydrolyzable nitrogen difference, with seed
Grain yield is the longitudinal axis, and alkali-hydrolyzable nitrogen is variable X, and the linear relation obtained between the two is as follows：
Y=108.96X (R2=0.8976)
In formula, Y indicates yield kg/hm2；X indicates alkaline hydrolysis nitrogen content mg/kg.
