Abstract
Respublikamizda sug‘oriladigan yerlar sizot suvlari sathining ko‘tarilishi, qurigan ko‘llardagi zararli tuzlarning shamol yordamida tarqalishi, yerlarni noto‘g‘ri sug‘orish tizimi va tuproq tarkibidagi zararli tuzlarning konsentratsiyasi ortishi oqibatida yerlarning sho‘rlanish darajasi yildan-yilga ortib, sug‘oriladigan yerlarning 50% maydoni turli darajada sho‘rlangan, natijada qishloq xo‘jaligi unumdor ekin maydonlarining kamayishiga va hosildorlikning keskin qisqarishiga sabab bo‘lmoqda. Bu esa respublikamizda sug‘oriladigan yerlarda ekin maydonlarining sho‘rlanish sabablarini aniqlash, sho‘rlangan tuproq tarkibidagi Na+, K+, Mg2+, Ca2+, SO42−, Cl−, HCO3−, CO32− ionlarini tahlil va skrining qilish, hamda tuproqlarning tarkibidagi tuzlar qanday tarkibli va qatlamlar bo‘yicha qanday tarqalganligi bo‘yicha ma’lumotlarni o‘rganib, ularning geografik tarqalish model xaritalarini yaratish va sho‘rlangan yerlarning sho‘rlanish darajasini kamaytirish borasida chuqur ilmiy tadqiqot va izlanishlarni olib borishni taqozo qiladi.References
