habka waraabka Your waa "dilay" ciidda

Waayo, dadka intooda badan, salinization ciidda waa labada la yaqaan iyo aqoon. Caan ah u leh, meelo badan sida xeebaha Shiinaha iyo dhulka gudaha leeyihiin qaybo badan oo dalka cusbada-alkali in la meel walba arki karo. Aasaasidda dalka cusbada-alkali sida la xiriira cimilada degaanka, ciidda, muuqaalka guud ee dhulka, geomorphology, cilmi dhul iyo arrimo kale. Alkalinization. Aan la aqoon waa in salinization ciidda ee beeraha ee ay keento tallaabooyin aadanaha macquul ah aan si fiican u fahamsan yahay.
Unreasonable human measures are mainly due to the unreasonable irrigation and drainage system, excessive irrigation, poor drainage, causing the groundwater level to rise, resulting in soil salinization, which is called soil secondary salinization. Saline-alkali land is increasing every year, because of the “contribution” of human beings. There are more and more secondary salinization sites, and about 10 million hectares of land are discarded each year due to secondary salinization of the soil.
According to research, the two rivers of one of the world’s four major civilizations, the main cause of extinction is the secondary salinization of soil.

Sidee hogaanka waraabka macquul ahayn in salinization ciidda?
Salinization ciidda, marka la eego fudud, waa in cusbadii wxbarashada on dusha sare ee carrada ka badan dulqaadka ee geedka iyo saamayn ku koritaanka caadiga ah ee geedka.

Flood irrigation

 Haddii ay tahay hoose ama sare, inta badan cusbada wxbarashada on dusha sare ee carrada ka yimaado dhulka, iyo dhulka hoostiisa soo baxdo in ay dusha u dhow dusha sare by tallaabo gaddoonka ah, keeno cusbo dusha sare ee ciidda.
The key to this is “groundwater rise.” If the amount of irrigation is too large, the water will penetrate down a lot, the drainage will be poor, the groundwater level of the cultivated land will rise, the groundwater will get closer and closer to the ground, and the salt carried in the water will easily reach the surface.
In this process, it is necessary to introduce a strong assist in the accumulation of salt on the surface – strong evaporation.
When groundwater brings soil salinity to the surface, strong evaporation will quickly turn the water into water vapor, unable to continue to carry salt, and the salt will stay on the soil surface. After a period of ascending-accumulating cycles, the surface of the soil accumulates salt, and for a long time, the soil will be salinized.
The secondary salinization of soil mainly occurs in the arid and semi-arid areas with strong evaporation, and the evaporation is greater than the rainfall. It is distinguished from the native salinization of the soil, mainly as a result of human economic activity.

Secondary salinization of soil

 Habka daaweynta salinization Ciidda

Daaweynta salinization Ciid ayaa had iyo jeer dhibaato weyn soo wajahay by saynisyahano ciidda. Haddii ay tahay salinization hoose ama salinization sare, tallaabooyinka la mid yihiin. Habka aasaasiga ah ee maamulka waa in la gooyay dhulka u kaca-cusbo habka raasamaal kor-uumi.
Improve agricultural drainage system
Inta ka waraabka, dheecaan, qoofalan, anti-siibatay iyo maamulka kale ee muhiimka ah. Biyaha cusub (Roob ah ama waraabka daad) waxaa loo isticmaalaa in mayr ciidda, iyo nidaamka dheecaan ka saaro qoyaanka ciidda xad-dhaaf ah ka soo ciidda ee waqtiga. Biyo nadiif ah iska maydh karaa ciidda iyo qaado cusbo dheeraad ah. Marka labaad, heerka biyaha dhulka la xakameyn karaa si qoto dheer ah nabad ah, hoos u gaabis uumi ciidda iyo yaraynta dhaqdhaqaaqa cusbo kor.
Film ciidda
Iyada oo daahan ciidda, waxaa looga hortagi karaa dusha sare ee carrada ka soo taabtaan jawiga, loo yareeyo uumi iyo in la yareeyo u kaca dhulka.
Habka isbedelka ciidda
si toos ah bedeli ciidda ee dusha biyaha cusbada-alkali ah in ciidda oo tayo sare leh. Beerto dalagyada cusbo-dulqaad ayaa sidoo kale daaweyn caadi ah.
For secondary salinization, the most important thing is to improve the irrigation and drainage facilities to prevent excessive irrigation during irrigation; after irrigation, the excess water can be discharged in time. The agricultural drainage system is currently the most widely used and effective solution. It fundamentally cuts off the cyclical process of groundwater rise-salt up-evaporation and salt accumulation. The rest of the methods are improvements under existing conditions.
