Phytocenotic characteristics of Kalidium caspicum, Halocnemum strobilaceum pasture variety in Karakalpak Ustyurt

Abstract

The article presents the phytocenotic characteristics of the Kalidium capsicum, Halocnemum strobilaceum pasture variety (PV), which is a part of the Halocnemum strobilaceum pasture type. The described type of pasture is widespread in the central part of the Karakalpak Ustyurt. Kalidium capsicum, Halocnemum strobilaceum pasture variety (PV), on wet and plump salt marshes, with Haloxylon ammodendron, H. strobilaceum on gypsum plump salt marshes, with the participation of Reaumuria songarica, Kalidium caspicum on cones of temporary watercourses in combination with Anabasis salsa is located in the Kungrad district, geographical points: Barsakelmes, Shorja. The area of the pasture variety (PV) is 36075 ha. The total projective cover of the PV is 15 %. The high proportion in vegetation is assigned to real halophytes: Haloc^mum strobilaceum - 40 %, and K. caspicum slightly less - 33 %; a smaller share on Haloxylon am-modendron - 20 % and a small part on Anabasis salsa - 7 %. All species except Halocnemum strobilaceum and Kalidium caspicum as assemblers of this plant community are found isolated and their role in the addition of the projective cover of the herbage is small. According to the results of the study, we see that due to the arid climate, the eaten part of the forage mass of the Kalidium capsicum, Halocmmum strobilaceum pasture variety is low and ranges from 1.9 to 4.2 c/ha. According to the yield indicators, the K. caspicum, Halocmmum strobilaceum pasture variety can be recommended for use as autumn-winter pastures.
