BUXORO VOHASI QUMLI CHOʻL TUPROQLARINING AGROEKOLOGIK HOLATI VA ULARNING UNUMDORLIGINI OSHIRISH YOʻLLARI
Abstract
Ushbu maqolada Buxoro vohasining qumli cho‘l tuproqlari, ularning kelib chiqishi, agrokimyoviy va agrofizikaviy xususiyatlari hamda cho‘llanish va sho‘rlanish jarayonlarining tuproq unumdorligiga ta’siri o‘rganilgan. Tadqiqot davomida vohaning chekka hududlaridan tuproq namunalari olinib, mexanik tarkibi, gumus miqdori va sho‘rlanish darajasi tahlil qilindi. Natijalar shuni ko‘rsatadiki, qumli cho‘l tuproqlarida organik moddalar miqdori nihoyatda past ($0.4-0.8\%$), suv ushlab turish qobiliyati zaif va shamol eroziyasiga moyillik yuqori. Maqolada ushbu tuproqlarning unumdorligini oshirish, tomchilatib sug‘orish texnologiyalarini joriy etish va fitomeliorativ tadbirlar orqali cho‘llanishga qarshi kurashish choralari ilmiy asoslab berilgan.
