Description
Technical field
The invention patent relates to reclamation of salinep-alkali soil fields, are particularly suitable for stickiness salt-soda soil soil property, and in particular to a kind of salt
Improve to alkali the system and method for rice cultivation.
Background technique
Jiangsu and Zhejiang Provinces area is had a large population and a few land, and land use situation is very nervous, to implement Jiangsu and Zhejiang Provinces Regional City requisition-compensation balance, is ensured
Regional economy sustainable development, it is very urgent that start quickly makes ground engineering.Therefore, become arable land to coastal area beach saline-alkali
The important goal on ground is made, wherein it is more significant to make ground benefit for salt-soda soil paddy field.Straw-returning is sharp as the farm technology of early stage
For if No. 201610550488.4 patents are using rice stalk as every salt deposit, cutting off transmission salt capillary in alkaline land improving,
Salt-soda soil is improved with this.Authorization Notice No. is that the Chinese utility model patent of 206775972U discloses a kind of salt-soda soil plant species
Phytem system, the salt-soda soil plant planting system includes the saline and alkaline separation layer arranged from the bottom to top, soil improvement layer, vaporization prevention
The micro- profit dropper drive salt device composition for layer and the lateral arrangement of preserving soil moisture, the saline and alkaline separation layer is by organic fertilizer, cobblestone, rough sand
Composition, the soil improvement layer are made of components in certain proportion such as saline-alkali soil, organic fertilizer, water-retaining agent, cotton seed hulls, desulfurized gypsums, institute
It states vaporization prevention soil moisture conservation layer and is located at upper soll layer, be made of cotton stalk crushed material or other agriculture and forestry organic waste materials, form is compacting
Or the blanket structure worked out, micro- profit drive salt device is managed by micro- profit and water system forms, and buries in soil improvement layer
It is interior, and be located above root system of plant.
But in the actual operation process, with returned on underground water or natural precipitation moisture under seep, by the stalk layer in soil layer
After being totally submerged, transmission salt capillary remodeling in upper layer under evaporation can fail rapidly every salt effect in the short time.
Summary of the invention
The present invention provides a kind of system and method for alkaline land improving rice cultivation, using rice straw as biological material
Material, and combine plastic hose that constantly underground water is discharged as salt discharge water hidden pipe under cultivation layer, it is set up out in the case where layer is cultivated in paddy field
Void layer effectively inhibits the underground water accumulation of salt in the surface soil using the mechanism that siphon sky breaks.
A kind of system of alkaline land improving paddy planting rice, including base, the stalk layer being laid in base and is located at

It is further preferred that closed conduit depth is 60cm；Width is 30cm；10m is divided between adjacent closed conduit.
Preferably, radial section 8~12cm of Zhou Changwei of the plastic hose, moulding hose materials can be PE, PVC, modeling
Open aperture processing in the shape hose whole body.
Preferably, the stalk layer is laid with smooth as far as possible, and thickness is uniform.
Preferably, the stalk layer with a thickness of 5~20cm.Further preferably 10~15cm.Thickness herein refers to
Thickness after coating soil pressure reality.
Preferably, paddy field cultivation layer with a thickness of 25~40cm.Further preferably 30cm, paddy field are cultivated in layer
Layer is rice cultivation layer, lower layer is silt bottom；Air layer is formed between stalk layer.
Preferably, the methane gas that the gas blanket every salt is formed by the air under former earthing or straw anaerobic generates
It generates.
Preferably, the silt bottom is by after the water storage of paddy field, soil is battered down and formed not in cultivation layer bottom by rotary tillage machine
Permeable airtight layer, and every the gas blanket of salt just below silt bottom.
To make more smoothly to drain, it is preferable that 5~10 ° of the gradient is arranged in the closed conduit.The further preferably slope of 5 ° of setting
Salt ground water is discharged to field two sides in degree.
The present invention also provides a kind of methods of alkaline land improving rice cultivation, include the following steps:
(1) native face is bulldozed by bull-dozer, and rooter is digged, 25~40cm of depth of turning soil；
(2) whole paddy stalk is layered on and digs Tu Mianshang, bull-dozer returns soil covering, forms stalk layer；Paddy stalk
Laying depth by stalk layer after earthing with a thickness of 5~20cm in terms of；
(3) ditching machine, which is ditched, puts pipe, 50~60cm of pipe laying depth, covers earthing after paddy stalk on plastic hose, is formed
Closed conduit, stalk of stalk layer itself extend in closed conduit as biological culvert pipe, and plastic hose water outlet is extended down to outside field；Adjacent closed conduit
Between spacing be 8~12m；
(4) field is impregnated, the rotary tillage desalinization of soil by flooding or leaching, and part stalk is ploughed under in paddy field cultivation layer during rotary tillage；
(5) it adds organic fertilizer and conditioner is increased fertilizer；
(6) then salt resistance Rice Cropping carries out rice management；Water is maintained in paddy field in the entire paddy growth period to cover
Lid.
The present invention combines closed conduit that underground water is constantly discharged using the support of rice bar, forms a gas in the case where layer is cultivated in paddy field
Layer, the principle broken using siphon sky, has separated being delivered up for brackish water；Rice bar returns to rice straw as biological culvert pipe by
Layer salt ground water is directed in closed conduit.
Compared with prior art, the invention has the following beneficial effects: (1) improved process is simple, easily implements operation, be not necessarily to
Deep layer is digged, and cooperation commonly ploughs machine with stronger operability；(2) it can use the extra rice straw of former years around,
Waste utilization；(3) newly change content of organic matter deficiency in salt-soda soil, addition rice bar rots, and humus can enhance soil water-retaining
Keeping fertility reduces soil hardening；(4) newly change that often microbial biomass is few in salt-soda soil and type is few, with adding for good farmland stalk
Add, a large amount of microorganisms can be brought into, enhances soil vitality；(5) biological culvert pipe is mutually cooperateed with closed conduit, cultivates layer and stalk in paddy field
One layer of gassiness clearance layer is formed between layer, has separated being delivered up for brackish water.
