Abstract :

The aimes of this research are increase rangeland production of desertes of central Iran and modification of the prevailing conditions fragile wilderness areas through proper identifying the species and planting them in came into force. In this study, three species: Seidlitzia rosmarinus, Nitraria schoberi and Zygophyllum eichwaldii by planting potted seedlings treated without operation rippering (breaking the hard layer) was conducted in a split plot based on randomized complete block design. Rainfed culture was conducted in March and only in the first year of planting and irrigation was 3 times per year. Traits within 3 years of the project, including survival, height growth, vegetation canopy and production. Statistical analysis of the data showed  that  the  effect  of  ripper  stay  survival,  height  growth  on  Seidlitzia  rosmarinus meaningless and maximum vegetation canopy diameter (121.7cm) and production (978 gr) were treated without treatment. Nitraria schoberi was not affected by the plant survival ripper, but  the  highest  growth  in  height  (63.7  cm),  vegetation  canopy  diameter  (100  cm)  and production (1413.3 gr) was treated ripper. Ripper treatment on Zygophyllum eichwaldii consists of all the characters and most survival (86%), high (63.4 cm), vegetation canopy diameter (73.4 cm) and production (287 gr) treated with ripper has been made. Therefore, Manysurvival and vegetation canopy rate, priority of culture in the region Seidlitzia rosmarinus, Nitraria schoberi and Zygophyllum eichwaldii, respectively. The ripper do not effected on growth and survival of Seidlitzia rosmarinus but effected on survival, height growth, canopy and the production of the Nitraria schoberi and Zygophyllum eichwaldii species.
