Abstract
The drained bottom of the Aral Sea covers an area of about 6 million hectares, of which 3.2 million hectares are located on the territory of the Republic of Uzbekistan. In addition to the fact that salt is spread from the drained bottom, dust and sand causing enormous damage to the environment, on the drained bottom there is a forest suitable area of 1.5 million hectares where it is possible to create desert shrub agrophytocenoses. The purpose of the work was to develop the most effective methods for creating desert agrophytocenoses on forest suitable types of bottom sediments of the dried bottom of the Aral Sea and the selection of desert forage plants to increase the productivity of the created pastures. Studies shown that when using focal, pasture protection and reclamation-fodder methods, as well as such fodder plants as teresken, boialich, keyreuk, it is possible to create pastures with a fodder capacity of up to 500 fodder units per hectare. This will increase the number of grazed animals by 20-30%. The field of application of the results arising from this work are forest suitable types of bottom sediments of the drained bottom of the Aral Sea. The drained bottom of the Aral Sea is a reserve of a forage base for animals in the near future, which will give a new impetus to the development of animal husbandry in the Aral Sea region, and at the same time, fodder plants, fixing the soil of the drained bottom of the Aral Sea, will significantly improve the ecological situation in the Region.
Highlights
Deserts and semi-deserts in the Republic of Uzbekistan occupy 65% of the territory, the main part of which is represented by treeless natural pastures and sand dunes
A low percentage of employment with forest plantations contributes to the development of wind erosion, which impedes the natural regeneration of pasture plants, causes low productivity of pastures and full or partial degradation of land [1-5].The problem, which today is in dire need of a solution, is especially important for Uzbekistan during the period of population growth
The technology of creating desert pastures was studied, an assortment of forage plants was selected, and the productivity of the created agrophytocenoses was taken into account
Summary
Deserts and semi-deserts in the Republic of Uzbekistan occupy 65% of the territory, the main part of which is represented by treeless natural pastures and sand dunes. Unsuitable types of bottom sediments occupy an area of about 35%, and the area on which desert pastures can be created is 1.5 million hectares [8] In this region, with the correct use of scientific recommendations: Novitsky Z.B. - Recommendations on methods for creating pastures on the drained bottom of the Aral Sea (Tashkent, 2014), Recommendations for creating desert pasture agrophytocenoses on the drained bottom of the Aral Sea (Tashkent, 2017), Recommendations on the creation of pastures from fodder plants on weakly overgrown sandy sediments subject to deflationary processes on the drained bottom of the Aral Sea (Tashkent, 2020), it is possible to create pastures with a productivity of [400-500] fodder units per hectare [10-13]
