Abstract
The invention relates to alkali discharging improved method for saline land. The trench is one way paralleled or crossed vertically and horizontally with different density. Its bottom is filled with a layer of sand with 3-37cm thickness to form underground alkali discharging sand trench connected with alkali discharging trench, drew water to discharge alkali. The trench is 29-60cm. Its bottom is filled with a layer of sand with 3-27cm thickness. Deep plowing is processed to make furrow depth reach 16-33cm in which the broken stalk or sand is splashed with 3-10cm. The invention has the advantages of little investment, good effect, short circle etc.
Description
Technical field
The present invention relates to a kind of alkali-removing modifying method far alkaline land.
Background technology
At present the alkali method that changes in salt-soda soil commonly used mainly contains: 1, row's alkali ditch wild-flooding method, 2, bury Pipe for draining alkali wild-flooding method, 3 underground, take surface saline and alkaline layer method away, 4, in addition, the somebody has applied for beating the national patent of alkaline discharging well wild-flooding method.Through the discovery of inventor's long-term observation, method 1 and 3 has the defective that changes the alkali weak effect, and method 2 has investment greatly, and the defective that the fertility loss is serious, method 4 have investment greatly, the defective of DeGrain.Above-mentioned three kinds of methods are all given prominence to exist and are changed long problem of alkali cycle.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective of prior art, provide a kind of investment little, effective, the alkali-removing modifying method far alkaline land that the cycle is short.
For achieving the above object, alkali-removing modifying method far alkaline land of the present invention in turn includes the following steps: level land, 0.4-8 rice excavates dark 26-60 centimetre zanjon at interval, described zanjon be unidirectional parallel ditch or intersect in length and breadth, in length and breadth to the different parallel ditch of density, sand one bed thickness 3-37 centimetre of the zanjon bottom landfill of holding successfully forms underground row's alkali sand furrow; Dig the row's alkali ditch that is communicated with underground row's alkali sand furrow, beat ground Leng, diversion irrigation row alkali.The sand layer that communicates successively with row's alkali major groove, because good water permeability, can be as the dark drainage channel of cheapness; And the manufacturing process of row's alkali ditch is simple.During irrigation row alkali, behind the water-soluble saline and alkaline composition of separating in the soil, i.e. infiltration downwards is when being penetrated into plough sole, because the impermeability of plough sole can be subjected to stopping of plough sole, to laterally flowing, when flowing to the sand layer, the salt buck again can the row's of flow direction alkali ditch at the sand layer, thus the row's of realization alkali purpose.Therefore, it is little, effective that it has investment, the advantage that the cycle is short.
As optimization, described zanjon 29-60 centimetre, the thickness of zanjon bottom landfill sand is 3-27 centimetre, deep plough and make ditch dug with a plow reach 16-33 centimetre deeply, during deep ploughing in ditch dug with a plow the broken straw rod or the sand of dispenser 3-10 cm thick.When arranging alkali, infiltrate broken straw rod or sand layers that the ditch dug with a plow bottom is infiltrated in 23 centimetres of arable layer salt bucks meetings earlier, alkali sand furrow, row's alkali ditch are arranged in inflow successively again, thus the row's of realization alkali.In addition,,, also have the effect of chesson, also can be used as fertilizer improvement salt-soda soil by unfreezing because the broken straw rod layer is rich in moisture.Because its row's alkali speed is moderate, has both helped saline and alkaline abundant dissolving, can guarantee percolation flow velocity again, row's base strength is big, can also shorten the alkali cycle that changes greatly.Can also adapt to the betterment of land of different saline and alkaline degree.
As optimization, the cross section of zanjon landfill sand layer is up-narrow and down-wide.Help keeping the sand layer loose, keep the drainage performance of long period.
As optimization, strip a field earlier surperficial 3-5 centimetre salinization topsoil of heavy saline is leveled land again.Help reducing to arrange the alkali burden, improve row's alkali speed.
As optimization, for the first time behind the diversion irrigation row alkali, plough again, the row's of watering alkali.Help accelerating the saline and alkaline row's alkali speed of oozing of arable layer under water.
As optimization, plough, water, wash, ooze under the last row, plough to water under the row of washing and ooze repeatedly.According to saline and alkaline degree difference, can select to plough to water under the row of washing to ooze number of times.
As optimization, execute farm manure during the arable land.Help improving soil permeability power, accelerate to change alkali speed.
After adopting technique scheme, it is little, effective that alkali-removing modifying method far alkaline land of the present invention has investment, the advantage that the cycle is short.

Fig. 2 is the D structure schematic diagram in row's alkali field of alkali-removing modifying method far alkaline land formation of the present invention.
The specific embodiment
Embodiment one, shown in Fig. 1-4, alkali-removing modifying method far alkaline land of the present invention in turn includes the following steps: level land, 0.4-8 rice excavates dark 29-60 centimetre zanjon at interval, described zanjon is the parallel ditch that intersects in length and breadth, and its mesosulcus is many, and traverse furrow is one, sand one bed thickness 3-27 centimetre of the zanjon bottom landfill of holding successfully forms underground row's alkali sand furrow 1; Deep ploughing also makes ditch dug with a plow reach 16-33 centimetre deeply, during deep ploughing in ditch dug with a plow the broken straw rod layer 2 of dispenser 3-10 cm thick; Dig the row's alkali ditch 3 that is communicated with underground row's alkali sand furrow 1, beat ground Leng 4, diversion irrigation row alkali.The cross section of zanjon landfill sand layer is up-narrow and down-wide.Strip a field earlier surperficial 1-7 centimetre salinization topsoil of heavy saline is leveled land again.For the first time behind the diversion irrigation row alkali, plough again, the row's of watering alkali.Plough, water, wash, ooze under the last row, plough to water under the row of washing and ooze repeatedly.Execute farm manure when ploughing again.Described broken straw rod layer can be replaced by the sand layer, and sand can be replaced by sandy soil.
Embodiment two, alkali-removing modifying method far alkaline land of the present invention in turn includes the following steps: level land, 0.4-8 rice excavates dark 26-60 centimetre zanjon at interval, and described zanjon is unidirectional parallel ditch, sand one bed thickness 3-37 centimetre of the zanjon bottom landfill of holding successfully forms underground row's alkali sand furrow; Dig the row's alkali ditch that is communicated with underground row's alkali sand furrow, beat ground Leng, diversion irrigation row alkali.The cross section of zanjon landfill sand layer is up-narrow and down-wide.Strip a field earlier surperficial 1-7 centimetre salinization topsoil of heavy saline is leveled land again.For the first time behind the diversion irrigation row alkali, plough again, the row's of watering alkali.Plough, water, wash, ooze under the last row, plough to water under the row of washing and ooze repeatedly.Execute farm manure when ploughing again.
The useful additional described sand of deciding can be replaced by sandy soil.
