Abstract

The invention provides a device for preventing permeation of a paddy field bed and discharging saline-alkaline water in improved saline-alkali soil. The device is composed of a paddy field bed, a ridge body, permeation preventing plastic mould layers, a saline-alkaline water permeable filter hood, a water discharge pipe and a valve. The device is characterized in that the paddy field bed higher than the ridge body on the natural ground is built on natural saline-alkali soil; and one or two permeation preventing plastic mould layers are laid at the bottom of the paddy field bed and used for preventing water in the paddy field bed from permeation and preventing salt and alkali in the natural saline-alkali soil from accumulation in the paddy field bed. The device has the following beneficial effects: the saline-alkaline water obtained through artificial irrigation in the paddy field bed is discharged from the water discharge pipe into a deep ditch via the saline-alkaline water permeable filter hood; the saline-alkaline water produced by drenching the natural saline-alkali soil with rain is discharged from the soil with the saline-alkaline water into the deep ditch; and the device has the advantages of simple structure, low cost and obvious effect on increasing the yield per mu of rice, thus being a new tool for controlling the saline-alkali soil.

Description

Paddy field, a kind of improvement saline land bed is anti-to be soaked into and salt discharge buck device

Technical field

The present invention relates to the water bed and the drainage arrangement field of the anti-water saturates of a kind of paddy field of salt affected soil improvement, improvement, paddy field, particularly a kind of improvement saline land bed is anti-to be soaked into and salt discharge buck device.

Background technology

At present, the untillable saline land of China accounts for the sixth of the area that can till the land; Constituent analysis shows that in the heavy salinized ground soil, organic matter is higher than 2.6 times in mellow soil ground soil through soil nutrient; Because saline-alkali soil saliferous, alkali number height, except that alkali grass plant can grow, crops, plant all can not grow; Through artificial diversion irrigation, make the soil of upper strata, saline land 10～30CM soil depth, salt and alkali component can reach the standard of cultivating.The salt in saline land and alkali are unsettled chemical substances, and along with environmental temperature rises to 30～50 ℃, humidity was at 70～99% o'clock; Saline-alkali soil location after improvement, the salt of natural salt affected soil is learned material with alkalization below degree of depth 30CM, and beginning is toward ground direction anti-saline and alkaline (anti-halogen phenomenon); The crop root part cell membrane of salt pair growth destroys, and causes crops withered, natural salt affected soil; Press different depth (thickness) 40 CM～300CM, anti-saline and alkaline toward ground, need centuries to several ten thousand years; Manual work is drawn irrigation and is changed heavy salinized ground, can only control table and not effect a permanent cure.

Summary of the invention

The present invention is directed to existing salt affected soil and wash the technical deficiency that salt row alkali is administered existence, provide paddy field, a kind of improvement saline land bed to prevent soaking into and salt discharge buck device.

The technical scheme that the present invention adopted: paddy field, a kind of improvement saline land bed is anti-to be soaked into and salt discharge buck device; By paddy field bed, ridge stage body, anti-ly soak into plastics mould layer, improvement back soil, ridge platform group, pass through saline and alkaline water filtration cover, drainpipe, valve constitute; It is characterized in that in saline and alkaline naturally ground; Build the paddy field that exceeds 30～60CM ridge, nature ground stage body around getting up by laying bricks or stones, water logging is leaked in one deck to the two layer anti-paddy field bed of shop, paddy field bed bottom, and salt is learned composition with alkalization in the prevention nature saline land; On return the anti-plastics mould layer that soaks into that is impregnated in the bed of paddy field, ridge stage body, the ridge platform face of helping in the paddy field around the bed is covered with one deck or two layers of anti-plastics mould layer that soaks into.

Paddy field, described a kind of improvement saline land bed is anti-to be soaked into and salt discharge buck device, it is characterized in that the stage body place, ridge of the draining zanjon direction that bed is corresponding in the paddy field, establishes a salt discharge buck device; Its structure is to soak on the plastic layer anti-, and a drainpipe is installed, and it is inner to insert the paddy field bed to drainpipe; Drainpipe is adorned one and is passed through saline and alkaline water filtration cover, on the drainpipe outer face, the valve of a control salt discharge soda water is installed; Drainpipe soaks on the plastics mould anti-through nut driving, and sealing tightens together, through the paddy field bed inner salt buck of man-made irrigation; From drainpipe, enter in the draining zanjon, its draining zanjon degree of depth is 0.6～1.2M, the natural salt alkaline earth; Can water out the salt buck with the pouring of rainfall, from saline and alkaline water and soil earth, enter in the draining zanjon.

Paddy field, described a kind of improvement saline land bed is anti-to be soaked into and salt discharge buck device; In rice test field, heavy salinized ground of Academy of Agricultural Sciences, through test in 2010～2011, the heavy salinized ground of improvement; The per mu yield paddy rice is 580～600 kilograms; Be higher than 500 kilograms of local common rice average yields, soil in the paddy field bed that improvement is administered has reached paddy rice and has planted the standard that conforms.

Beneficial effect: paddy field, a kind of improvement saline land bed is anti-to be soaked into and salt discharge buck device, by paddy field bed, ridge stage body, anti-ly soak into plastics mould layer, pass through saline and alkaline water filtration cover, drainpipe, valve constitute, it is characterized in that in natural saline and alkaline ground; Build the paddy field that exceeds ridge, nature ground stage body around getting up by laying bricks or stones, bed bottom shop one deck or two layers of anti-plastics mould layer that soaks in the paddy field, water logging spills in the bed of anti-paddy field; Stop the natural salt alkaline earth saline and alkaline,, contain saline and alkaline water to washing out of man-made irrigation in the bed of paddy field through passing through saline and alkaline water filtration cover to paddy field bed internal return; Enter in the depth of water ditch from drainpipe, the natural salt alkaline earth can water out the salt buck with the pouring of rainfall; From saline and alkaline water and soil earth, enter in the draining zanjon, the present invention is simple in structure, and is with low cost; The effect that increases the paddy rice per mu yield is obvious, is the new way of administering the saline land.
