Description
Technical field
The present invention relates to agricultural non -point pollution control technology field, specially a kind of winter wheat presses down the pollution of area source of salt synergy
Control method.
Background technology
The formation of salinization soil is a long-term and complex process, the low plain varieties in saline-alkali areas During Growing Period of Winter Wheat north
Universal drought, the shallow low plain varieties in saline-alkali areas of underground water buried depth takes the interim easily anti-salt of soil in spring.Winter wheat is to water
Fertilizer is in great demand, but excessive fertilization increases the potential threat of secondary salinization again, and farming area is irrigated except meeting crop life
Length is needed outside water, also carries the function of elution agricultural land soil salinity.Broad irrigation pressure salt in farmland causes farmland nutrient loss, is to make
One of direct acting factor into farming water system eutrophication.While single saline and alkaline governance model can not meet pressure salt
The need for administering pollution of area source, hydraulic engineering measure and agro-ecology measure must combine closely and could preferably administer soil salt
Stain, while reducing pollution of area source.Research both at home and abroad was conducted a research work for a certain individual event control measures mostly in the past
Make, because the factor differences such as soil parent material, the natural environment of different zones are larger, desalting effect comparativity between each ameliorative measure
It is poor.Therefore, being come into operation we have proposed a kind of non-point source pollution control method of winter wheat suppression salt synergy, to solve above-mentioned ask
Topic.
The content of the invention
It is an object of the invention to provide the non-point source pollution control method that a kind of winter wheat presses down salt synergy, to solve the above-mentioned back of the body
The problem of being proposed in scape technology.
To achieve the above object, the present invention provides following technical scheme：A kind of winter wheat presses down the pollution of area source control of salt synergy
Method processed, the winter wheat presses down comprising the following steps that for the non-point source pollution control method of salt synergy：
S1：Summer maize straws, which smash to spread after returning to the field on the spot, covers earth's surface, by the native subsoiling of topsoil for planting earth's surface, makes anthropogenic soil
It is in small, broken bits, promote crumb structure to be formed；
S2：50~70kg/ mus of organic matter fertilizer is applied in soil after subsoiling, soil humic acid content is improved, increases soil
Buffer capacity；
S3：When sowing winter wheat, the nitrogenous fertilizer and phosphate fertilizer that are weighed according to proportional quantity are poured into the fertilizer groove of seeder and mixed
Uniformly, chemical fertilizer is manured into soil simultaneously during tractor-ploughing water furrow planting, and chemical fertilizer is not contacted directly with seed, seeder walk while pair
Wheat seeds and fertilizer cover native covering；
S4：Uniform on the table soil of covering to sprinkle suppression salt synergist, disposable to apply, top layer is sprinkled water wet to table soil after application
Untill profit；
S5：Soil moisture, air and temperature are adjusted, promotes absorption and utilization of the winter wheat to nutrient, reduces nutrient excessive
Accumulation and elution, mitigate the eutrophication of agriculture drainage ditch and phreatic water.
It is preferred that, in the step S1, mellow soil is answered when subsoiling is operated upper, subsoil under, ploughing depth 20~
25cm。
It is preferred that, in the step S1, when ploughing in spring, preferably plough shallowly, with kind with cultivated, suppression of being raked immediately after ploughing,
Insulation soil moisture conservation；Sprinkled water after being ploughed before summer corn planting dry field, improve soil texture；Autumn ploughing is carried out before soil freezes, by straw
Stalk smashes and carries out subsoiling to topsoil soils after returning to the field on the spot, makes anthropogenic soil is in small, broken bits to promote crumb structure to be formed, while jelly water is poured,
Utilize the loose soil property of the mechanism of freeze thawing.
It is preferred that, in the step S2, when surface soil alkalinity is stronger, every mu applies 30~40kg gypsum and is used as base manure conditioned soil
Earth.
It is preferred that, in the step S3, in winter wheat fertilization, dose presses 6.9~8kg/ mus of purity nitrogen respectively；Pure phosphate fertilizer
5.5~12kg/ mus.
It is preferred that, in the step S4, suppression salt synergist is the mixed of yellow humic acid, nitrogen-fixing bacteria, denitrifying bacterium and dry fine earth
Compound, wherein yellow humic acid：Nitrogen-fixing bacteria：Denitrifying bacterium：Dry fine earth=0.9:1:1.5:200.
It is preferred that, in the step S5, winter excavates Cold-proof Ditch, intercept heat conduction in farmland surrounding；The farmland of excavation
Irrigation canals and ditches can press salt in summer with draining, while in topsoil spreading, being incubated water conservation.
Compared with prior art, the beneficial effects of the invention are as follows：Present invention fertilising is with strong points, both saves fertilizer, it is ensured that
Volume increase, just field farming operation, only applies fertilizer once, winter wheat is turned over, sowed, fertilizing integrated, reduces farming per season crop
Operation, alleviates peasant household's work, and saving of labor, laborsaving, peasant is easy to receive, and is easy to operation；In farmland, surrounding excavates the water of Cold-proof Ditch
Sharp engineering measure is combined with agronomy agro-farming measure, it is to avoid frequent disturbed soil, and retaining is played to soil and protects Moisture effects, is added
Soil is held and utilized to the storage of limited water resources；The present invention press down to topsoil subsoiling, applying organic manure, using soil salt synergist,
The agro-farming such as farm ditch draining agronomy and the progress of agriculture project monotechnics collect excellent and filled a vacancy, and can increase soil water storage fertilizer-preserving ability and suppression
Salt manufacturing point is moved up, at the same reduce Lu Yuan nutrients into water body cause pollution of area source the problem of.
