| In order to provide a correct and technical model of the construction of a rainfed almond orchard, this field research was carried out in the agricultural year of 2018-2019 in North Khorasan province, Bojnord region, Badranlu area, Serivan Tappe village, and on the land of the farmer and with the participation of the farmer for 4 years. Almond variety Faranis (Shahrood 12) with Shokofeh variety (for pollination) which approved by the Agriculture and Natural Resources Research Center and has a certificate of health and authenticity, was prepared and cultivated and compared with local cultivars (seed based) of the region as a control. Climate parameters including precipitation, temperature, relative humidity and sunshine hours of the nearest meteorological station were obtained and analyzed. To fill the holes, high-quality topsoil (combined with rotted manure and mycorrhizal fungi in the amount of about 70 grams for each tree) was used. Seedling planting criteria (disinfection, root and top branch pruning, irrigation at the time of planting, soil restoration) were included in the work plan according to the instructions of the Education and Extension Institute. Rainwater harvesting system was established by observing the reduction of the runoff threshold and increasing the runoff coefficient, as well as the management of the runoff level. The spacing of the trees was 6 meters by 6 meters and in a semi-circle with a radius of 2.5 meters with a density of 267 plants per hectare. The semi-circular system was created after the planting operation. The catch percentage (more than 98%) and the growth status of the trees (20-40 cm per year) indicate the success of the research. Comparing the rainfall productivity in the region's rainfed wheat fields and existing rainfed almond orchards (local variety) indicates the existence of local capacities and capabilities in improving green water productivity for constructing or modifying rainfed almond orchards by observing the criteria and installing a rainwater harvesting system, deep root development and evaporation control. |
