LISIMETRIK TADQIQOTLARDA TUZ KO‘CHISH PARAMETRELARINI ANIQLASH UO‘K 532.543:626.80
Referat
Tuz almashinuvini tadqiq etishning asosiy vazifalaridan biri oʻrganilayotgan tuproq qatlamlarining alohida gorizontlarining strukturaviy xususiyatlarini, moddalarning harakatlanish qonuniyatlarini va ularni tavsiflash usullarini oʻrganish asosida berilgan shartlarga mos keladigan jarayonlar harakatining matematik modelini tanlashdan iborat.Ushbu maqolada g‘o‘zani egatlab sug‘orish sharoitida, jarayonning umumiy yo‘nalishidan mavsumiy og‘ishlarga e'tibor bermaslik mumkin bo‘lgan sharoitda tuz o‘tkazishni modellashtirishning ba'zi masalalari ko‘rib chiqilgan.
Lizimetrik tajribalar ma’lumotlariga ko‘ra, g‘o‘zani egatlab sug‘orishda ma’lum qalinlikdagi tuproqlarning o‘rtacha sho‘rlanishidan kelib chiqib, aeratsiya zonasidagi tuproqlarning statsionar tuz rejimi sharoitida tuz o‘tkazish parametrlarini aniqlash usuli ishlab chiqilgan. Ma'lumki, statsionar ion-tuz va suv rejimlari uzoq muddatli sug‘orish paytida yoki tabiiy sharoitda hosil bo‘ladi va aeratsiya zonasi jinslari va yer osti suvlaridan tuzlarni olib ketish va tuzlarning kirib kelishiga yordam beradigan muvozanat omillari mavjud bo‘lganda yuzaga keladi.
Tuproqlarning statsionar suv-tuz rejimi sharoitida tuz o‘tkazish parametrlarini aniqlashning taklif etilayotgan usuli, ham dala, ham laboratoriya tajribalari ma'lumotlariga ko‘ra, yuqorida qayd etilgan xususiyatlarni hisobga oladi.
Tuproqning aeratsiya zonasida tuzlarning statsionar taqsimlanishi va namlik harakatining doimiy tezligi bilan to‘g‘ri masalani hal qilish g‘o‘zani egatlab sug‘orishda aeratsiya zonasi jinslarida g‘ovak eritmalarining o‘rtacha minerallashuvini taxmin qilish imkonini beradi.
