Abstract
The invention discloses the soil bodys for improving newly-increased farmland water retention in soil to build method, belongs to soil remediation field.The present invention is when in use, based on soil organism model foundation, it can be general in the demand rule of soil nutrient, the deliverability of soil nutrient and fertilizer effect, on the basis of Rational Application organic fertilizer, the application quantity of nitrogen, phosphorus, potassium and middle and trace element fertilizer can be effectively analyzed.If arable land fertilizer application formula and distribution can be understood in the method that cultivated-land grade figure and crop allocation figure are superimposed, so that it may in conjunction with soil fertility subregion and nutrient balance method, obtain accurate region fertilizer application formula, provide good decision-making foundation for policymaker's scientific management.
Description
Technical field
The present invention relates to soil remediation fields, more particularly to improve the soil body construction side of newly-increased farmland water retention in soil
Method.
Background technique
Freshly plowed soil region it is with a varied topography, severe water and soil erosion has been carried forward vigorously since phase late 1990s and has been moved back
Also woods engineering is ploughed, ecological construction obtains remarkable effect.But the arable land of hill loess hills slope surface is greatly decreased after conceding the land to forestry, increasingly shadow
It rings and arrives household's behavior and grain security, thus channel becomes the important incision that loess plateau Zhi Gou makes land use intensively behind ground
Point.For a long time, since zanjon pluvial erosion, infrastructure construction lag, the difficulty of channel land use is big, low efficiency.Soil
It renovates as in due course replenished cultivated land, efficiently using the available land, optimization urban and rural land, reinforcing intensive land use, promote soil production capacity in ground
Important means is new period pool town and country, benefit agriculture-countryside-farmer, " people's livelihood engineering " is enriched people in strong village.It in recent years, is typical case with Yan'an
Loess hilly-gully region advance state revenue support control ditch make ground land control Important Project, planning and restoration channel
500,000 mu of soil, financial investment 4,800,000,000.Recently it is set for ensureing channel safety, improving channel basis with making studies have shown that controlling ditch
It applies horizontal and promotion channel agricultural productivity and plays positive effect.
But the existing soil body for improving newly-increased farmland water retention in soil builds method, can only mostly solve in the short time
Certainly water retention in soil, it is palliative.
Summary of the invention
It is insufficient that the purpose of the present invention is to solve existing freshly plowed soil earth moisture holding capacities, and conventional administering method, temporary solution
The problem of not effecting a permanent cure, and the soil body of the raising newly-increased farmland water retention in soil proposed builds method.
To achieve the goals above, present invention employs following technical solutions:
The soil body for improving newly-increased farmland water retention in soil builds method, includes the following steps；
S1, the data that weather, landform and soil nutrient content are carried out to freshly plowed soil earth region are acquired and are arranged, and the region is divided
For non-salinization soil area, salinization soil area and there is the potential soil salinization to form area；
S2, to draw in freshly plowed soil earth region, store and diversion works；Row, stagnant and the drainage system and river dike work let out
Journey carries out data acquisition and arrangement；
S3, the data acquired according to S1 carry out prepartion of land to freshly plowed soil earth region, prevent Micro-terrain Action soil salt from dividing again
Match；
S4, the data acquired according to S2, are transformed upgrading to freshly plowed soil earth region irrigation and drainage system with functions, and establish the filling of orderly function
Irrigate system；
S5, the data acquired according to S1 establish the organic mutation model of soil, and add organic fertilizer according to model.
Preferably, channel, ridge, edges of regions of pouring water and low be should be specifically noted that in the S3 when smooth freshly plowed soil earth region
Edge mima type microrelief in depression changes the generation of the soil salinization in obvious region, the measures such as intercepting ditch should be taken to be prevented when necessary
It controls.
Preferably, in the S4 after the irrigation and drainage system with functions upgrading of freshly plowed soil earth region, pass through draining control in irrigated area
Level of ground water will drench outside salt water discharge area in certain depth, and underground water buried depth is controlled except the short time in 0.7m-0.8m, long
Time controls in 0.8m-1.2m or so, and autumn and winter, surface soil is exposed, and soil evaporation is strong, controls in 1.2m-1.4m, and control
Freezing layer or less.
Preferably, the irrigation program in the S4 is determined according to plantation crops and this area soil situation, in which: is seeped
The area Lou great 450-580/ mu, the non-salt-soda soil 500-540 in area in leakage/ mu leaks the salt-soda soil Zhong Qu 600-640/ mu seeps
Leak the non-salt-soda soil 450-470 of cell/ mu leaks cell salt-soda soil 560-580M3/ mus.
Preferably, the organic mutation model of soil in the S5 the following steps are included:
A1, the data measured in S1 are brought into regionalized variable formula；
In above formula:It is variable of a certain property in spatial distribution of soil；
A2, the calculated result result in A1 is brought into half contrast formula；
。
In above formula:It indicates using h as the pairs of number of all observation points of spacing；And bring above-mentioned formula into linear mould
It is fitted in type, spherical model and exponential model, model etc., the direction of be fitted variation function model reflecting regional variable
Property, spatial autocorrelation distance etc. and randomness；
A3, by the design feature of the initial data of the regionalized variable in A2 and semivariance model of fit, bring following formula into:
In above formula:It is in pointIf the neighbouring measured value for doing acquisition；It is without observation pointOn it is interior
Insert estimated value；For the weight of representation space in semivariogram.
Preferably, it first has to calculate in semivariance model calculating process in the A2Scatter plot, it is then sharp
It is fitted with different types of model, obtains the parameter value and sum of squares of deviations of model, choose the smallest mould of sum of squares of deviations
Type type, finally with cross-validation method come the parameter of correction model.
Compared with prior art, the present invention provides the soil bodys for improving newly-increased farmland water retention in soil to build method, tool
It is standby following the utility model has the advantages that
1. the present invention, can the general demand rule in soil nutrient, soil nutrient based on soil organism model foundation
Deliverability and fertilizer effect, on the basis of Rational Application organic fertilizer, can effectively analyze nitrogen, phosphorus, potassium and in,
The application quantity of trace-element fertilizer.If arable land can be understood in the method that cultivated-land grade figure and crop allocation figure are superimposed to apply
Fertilizer formula and distribution, so that it may in conjunction with soil fertility subregion and nutrient balance method, obtain accurate region fertilizer application formula, be policymaker section
It learns management and good decision-making foundation is provided, raising freshly plowed soil earth moisture holding capacity that can be more convenient, and propose scientific filling
It irrigates and improves drainage system, improve standard of drainage；Network is formed, the permanent curing action of prevention and treatment soil salt marsh is played.Such as without drainage system
Guarantee, development irrigation, soil secondary salinization will be formed, original salinization soil will aggravate, and soil is once being formed
Soil secondary salinization and, it is heavy then not even a blade of grass grows gently from the underproduction, by first to freshly plowed soil earth region carry out it is smooth it is perfect after,
Appropriate fertilizer is added again, that is, the moisture holding capacity of soil can be improved, and soil is transformed.
