Abstract
Xozirda global iqlim o‘zgarishi sababli dunyoning xar bir joyida o‘ziga xos iqlim sharoitlari ko‘zatilmoqda. Mavjud cheklangan resurslar ta’biy xo‘jalik sharoitlari resurslarning tanqisligiga uchrab borilmoqda. Mazkur maqolada g’o’zani nazariy va dala tajribalari asosida tomchilatib sug‘orish tartibi, texnologiyasini ishlab chiqish uchun Surxondaryo viloyatida Angor tumani massivining tab’iy – xo‘jalik sharoitlarida o‘tkazildi. Iqlimning global o‘zgarishini xisobga olgan xolda, sugoriladigan yerlarning xavo-xarorati, xavoning namligi va uning yetishmovchiligini, yer osti suvlarining satxi, tuprok-meliorativ xolati, buglanishga va g‘o‘zaning transpiratsiyaga sarflanadigan suv mikdori, yangi rayonlashtirilgan g‘o‘zani agrobiologik xususiyatini xisobga olgan xolda bir kunlik, un kunlik, oy va sugorish davridagi mikdorlarini urganilgan, ilk bor tomchilatib sug‘orish usulidagi g‘o‘zaning tomchilatib sugorish tartibi ishlab chikishda «bioklimatik» usul kabul kilingan. G‘o‘zaning elementar sug‘orish meyori, sug‘orishlar soni, sug‘orishlar davri va mavsumiy sug‘orish meyori aniqlangan. G‘o‘zani tomchilatib sug‘orish tizimining real tuproq – meliorativ, gidrogeologik, gidrologik va xo‘jalik sharoitlarida elementlari aniqlangan. Tomchilatib sug‘orishda sug‘orish texnologiyasi keltirilgan. G‘o‘zani tomchilatib sug‘orishda egatlab sug‘orishga nisbatan afzalligi asoslangan.
