The phytogenic effect of different-aged black saxaul plants on the productivity of wormwood-ephemeral vegetation under the conditions of Karnabchul

The aim of the study is to determine the effect of different-age black saxaul plants on the productivity of wormwood-ephemeral vegetation through the study of the phytogenic field of this ephemeroid species. The phytogenic field of black saxaul has been studied by the phytomer method in the desert Karnabchul. The study showed that its influence in the minimum phytogenic field on the productivity of wormwood-ephemeral vegetation is negative, in the external part of the phytogenic field on bluegrass and forbs is positive, and on wormwood and sedge remains negative. The highest productivity indices are observed in them between the outer and inner and outer parts of the phytogenic field of the middle-aged generative plants of the edificator.
