metòd irigasyon ou se "touye" tè a

Pou pifò moun, salinizasyon tè se toude familye yo ak lòt abitye. Abitye ak li, anpil zòn yo tèl ke Lachin zòn kotyè ak zòn andedan gen gwo zòn nan saline-alkali peyi ki ka wè toupatou. se fòmasyon an tout moun ki tankou saline-alkali peyi ki gen rapò ak klima lokal yo, tè, relief, jomorfoloji, géologie ak lòt faktè. Alkalinizasyon. Abitye se ke salinizasyon nan tè nan agrikilti a ki te koze pa mezi rezonab imen se pa sa byen konprann.
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.

Kijan plon rezonab irigasyon salinizasyon tè?
Du salinizasyon, an tèm senp, se ke sèl ki te akimile sou sifas la nan tè a depase tolerans la nan plant la ak afekte kwasans lan nòmal nan plant la.
irigasyon inondasyon
Flood irrigation

 Kit se primè oswa segondè, pi fò nan sèl ki te akimile sou sifas la nan tè a soti nan dlo anba tè, ak dlo anba tè a leve nan sifas la tou pre sifas la pa aksyon kapilè, yo pote sèl nan sifas la nan tè a.
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.

 Du metòd tretman salinizasyon

Te Du tretman salinizasyon te toujou yon pwoblèm pi gwo fè fas a pa syantis tè. Kit se prensipal salinizasyon oswa salinizasyon segondè, mezi yo se menm jan an. Metòd la debaz yo nan gouvènans se yo koupe dlo anba tè monte-sèl monte-evaporasyon pwosesis la akimilasyon.
Improve agricultural drainage system
Sitou soti nan irigasyon, drenaj, labou k, anti enfiltrasyon a-yo ak lòt jesyon kle. Se dlo a fre (lapli oswa irigasyon inondasyon) itilize yo rense tè a, ak sistèm nan drenaj ekoulman imidite tè depase soti nan tè a nan tan. Dlo fre ka lave lwen tè a ak pran plis sèl. Dezyèmman, ka nivo a dlo anba tè ka kontwole nan yon pwofondè ki an sekirite, ralanti desann evaporasyon tè ak diminye mouvman sèl egal.
Du fim
Atravè kouch tè, li ka anpeche sifas la nan tè a soti nan rantre an kontak avèk atmosfè a, diminye evaporasyon ak diminye dlo anba tè ho yo.
Du chanjman metòd
Dirèkteman chanje tè a nan sifas la saline-alkali nan tè-wo kalite. Plante rekòt sèl-toleran se tou yon tretman komen.
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.
