Abstract
Tuproq unumdorligini saqlash va tiklash zamonaviy qishloq xo‘jaligining muhim muammolaridan biri hisoblanadi. Ayniqsa, uzoq muddat davomida intensiv dehqonchilik, mineral o‘g‘itlardan me’yoridan ortiq foydalanish, eroziya va oziqa elementlarining yuvilishi natijasida tuproqdagi o‘simliklar uchun mavjud mineral elementlar miqdori kamayishi mumkin. Shu nuqtayi nazardan, mineral silikatlarni mikrobiologik yo‘l bilan parchalab, ular tarkibidagi o‘simliklar uchun zarur elementlarni harakatchan shaklga o‘tkazuvchi silikat bakteriyalardan foydalanish istiqbolli biotexnologik yondashuvlardan biridir. Zamonaviy tadqiqotlarda silikatlarni erituvchi mikroorganizmlardan biologik o‘g‘itlar tarkibida foydalanish, tuproq unumdorligini oshirish, o‘simliklarning oziqlanishini yaxshilash hamda stressga chidamliligini kuchaytirish imkoniyatlari ko‘rsatib berilgan. Mazkur tezisda silikat bakteriyalarning tuproq unumdorligini oshirishdagi roli va ulardan biotexnologik foydalanish imkoniyatlar tahlil qilinadi.
