Abstract
The invention relates to a land transformation method, in particular to a saline and alkali land improvement method. The method comprises the following steps: the saline and alkali land to be improved to is changed into an alternant land for a trench land and ridges; a layer of fine flowing sand or sandy loess with thickness of 3-3.5 cm is evenly laid on the trench land, the saw powder and the chopped grass with thickness of 1-1.5 cm are laid, and the plowing depth is 5-15 cm and is not excessively deep; the trench land is filled with water during the watering process and the ridge cannot be filled with water as possible; the saline and alkali tolerant high-quality corn variety is selected and planted or the agropyron elongatum can be planted; after the young seedlings grow out, the traditional intertillage management is carried out; after the seeds are harvested, the straw returning is carried out; as for the land tillage in the second year, the sand with thickness of 2-5 cm is laid, the saw powder and the chopped grass with thickness of 1-3 cm are laid, then a certain amount of farmyard manure is applied and the rest is the same as the tillage in the first year; as for the land tillage in the third year, the ridges on both sides of the land are respectively taken as the lands with one eighth width during the tractor-ploughing process, so the trench land is increased, and other parts are repeated according to the tillage in the second year; as for the land tillage from the fourth year to the sixth year, the tillage method in the third year is repeated; and the improvement of the whole saline and alkali land is finished after six years. The invention can enable the saline and alkali land to be changed into a fertile land, thereby thoroughly harnessing the saline-alkali land.
Description
Technical field
The present invention relates to a kind of remodeling method of soil, specifically a kind of saline and alkali land improvement method.
Background technology
The soil, saline land hardens, some saline and alkaline grass of only growing, and the crops of not growing is a kind of significant wastage of land resources.At present, domestic and international processing method to the saline land mainly contains following several: salt discharge method, pressure salt method, stifled salt method.The salt discharge method is by a large amount of water, the saline land is washed for a long time, and the salt content on top layer, saline land is reduced; Pressing the salt method is to utilize natural precipitation or artificial big flood to irrigate, the salt that impels part along the soil pore space, the crack permeates downwards, takes the salinity of topsoil to bottom with water; Though said method can make the salt content on top layer, saline land reduce, and can not keep permanent, and needs a large amount of water sources.Stifled salt method is by transplanting soil moved in to improve the original soil removal and replacement to be carried out on the top layer, saline land, and not only quantities is big, and the resource of good soil also need be arranged, but As time goes on still keeps away unavoidable salinization of soil.ZL200510016634.7 " a kind of method of administering the renovation and utilization saline land ", mainly be by taking local ditching that separation layer is set on the ground at saline-alkali soil, the method of planting climing plant of watering is on a small quantity administered transformation salinity ground, it is less to plant its root floor space of climing plant, just can make its normal growth as long as administer the transformation root, its method also can only be planted grass, can not be a farmer.
Summary of the invention
The purpose of this invention is to provide a kind of simple a kind of saline and alkali land improvement method.
Concrete steps of the present invention are as follows:
One, levels land: can enter mechanical work and be as the criterion but the land readjustment that will improve reaches canal irrigation;
Two, saline and alkaline ditch is opened up wasteland: ground is dug several dark 15～25 centimetres canal ground, dig on the both sides and make the ridge platform, the saline land of improveing has been become the soil that canal ground and ridge platform replace; Also repair feed ditch and road;
Three, the farming on ground:
The farming on 1 year ground:
1. spread layer: at the thin trip sand or the chiltern loess of even layer overlay 3～3.5 cm thicks in canal ground, shop sawdust, broken careless 1～1.5 cm thick.To the saline land that weeds of especially severe do not have yet, the shop layer thickness should be near topsoil thickness;
2. plough: 5～15 centimetres of the arable land degree of depth, should not be dark excessively;
3. water: water is filled ground, does not allow water irritate as far as possible and goes up till the ridge platform;
4. select salt tolerant alkali superior corn kind, maize planting or to plant high stalk herbage also passable;
5. after seedling grows, undertaken by tradition intertillage management;
6. after seed gathers in, straw-returning;
The farming on 1 year ground:
Husky 2～5 cm thicks in shop, sawdust, broken careless 1～3 cm thick are executed some farmyard manures more in right amount, and all the other are 1 year cultivate together;
The farming on the 3rd year ground:
During tractor-ploughing, the ridge platform on both sides, canal ground is respectively got 1/8 wide for canal ground, the increase of canal ground width, the cultivating of other repetition 1 year;
The farming on the 4th to the 6th year ground: repeat the expedient of tillage in the 3rd year; Finish through 6 years full wafer alkaline land improvings like this.
Compared with prior art, the present invention has tangible technique effect and is:
The present invention can become the good farmland with the saline land, fundamentally administers the saline land.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the elevation on ground of the present invention,
Fig. 2 is the plane on ground of the present invention.
1. canal ground among the figure, 2. ridge platform, 3. horizon, 4. feed ditch, 5. road.
Embodiment
Concrete steps are as follows:
One, whole soil: can enter mechanical work and be as the criterion but the land readjustment that will improve reaches canal irrigation;
Two, saline and alkaline ditch is opened up wasteland: leave one dark 20 centimetres, wide 2 meters canal ground 1 every 2 meters, on dig and make ridge platform 2, like this soil of improveing has been become the soil that wide 2 meters canal ground 1 and wide 2 meters ridge platform 2 replace; Also repair feed ditch 4 and road 5;
