Vaš način namakanja je "ubijanje" tal

Za večino ljudi, zasoljevanje tal je tako poznajo in ne poznajo. Seznanjeni s tem, veliko področij, kot so Kitajska obalnih območij in celinskih območjih imajo velike površine solno-alkalnih zemljišča, ki jih je mogoče videti povsod. Nastanek take slane-alkalnih zemljišč se nanaša na lokalne klime, tal, topografijo, geomorfologije, geologije in drugih dejavnikov. Alkalinizacija. Seznanjeni, da je zasoljevanje tal za gojenje z neupravičenimi človekovih ukrepi povzročajo tudi ne razume.
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.

Kako nesmiselno namakanje vodstvo salinizacija tal?
Tla salinizacija, na preprost način, je, da je nabralo sol na površini zemlje presega toleranco rastlin in vpliva na normalno rast rastlin.

Flood irrigation

 Ali je primarna ali sekundarna, večina soli nakopičenih na površini zemlje prihaja iz podtalnice in podzemne vode dvigne na površino v bližini površine s kapilarnim, prinaša sol na površino zemlje.
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.

 Postopek obdelave salinizacija tal

Tla zdravljenje salinizacija je bil vedno velik problem, ki ga znanstveniki tal s katerimi se soočajo. Ali je primarni salinizacija ali sekundarni salinizacija, ukrepi so podobni. Osnovna Postopek upravljanja je prekinil up-uparjenjem postopek zbiranja podtalnice dvig-sol.
Improve agricultural drainage system
glavnem iz namakanje, odvodnjavanje, preplavljanje, proti vdoru in druge ključne upravljanja. Sveža voda (dež ali poplav namakanje) se uporablja za izpiranje zemlje, in drenažni sistem izprazni odvečno vlago tal iz tal v času. Sveža voda lahko odplavila tla in se več soli. Drugič, lahko gladina podzemne vode je treba nadzorovati, da se varno globino, upočasnjuje izhlapevanje tal in zmanjšanje pretoka soli navzgor.
Tla film
S premazom tal, da lahko prepreči površino zemlje, ki prihajajo v stik z atmosfero, zmanjša izhlapevanje in zmanjšanje dvig podzemne vode.
Postopek tal sprememba
Neposredno spremeniti zemljo v solno-alkalnih površine do visokokakovostne tal. Obdelovanjem soli odporen tudi skupni zdravljenja.
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.
