Scope

This document specifies the terms and definitions, site selection, pre-sowing preparation, sowing, irrigation, fertilization, and pest and weed control for the intercropping of sorghum and sesbania to save water and suppress salinity in the saline-alkaline soils of the Yinghe Irrigation District in Ningxia. This document is applicable to the production of sorghum and sesbania intercropping in the saline-alkaline soils of the Yinghe Irrigation District in Ningxia. Terms and Definitions The following terms and definitions are applicable to this document. 3.1 Sorghum (Sorghum bicolor) - Sesbania cannabina intercropping The method of planting sorghum and sesbania in a certain row ratio in saline-alkaline soils. 4 Site Selection Select plots with a soil salt content of 1 g/kg ~ 5 g/kg, a pH of 7.5~9.0, and a complete irrigation and drainage system. 5 Pre-sowing Preparation 5.1 Variety Selection Select hybrid sorghum and sesbania varieties that are resistant to salinity and alkalinity and have been registered or approved by the state, suitable for cultivation in the Yinghe Irrigation District in Ningxia. The seed quality meets the requirements of GB 3543. 5.2 Tillage After the harvest of the previous crop in autumn, plow and till the soil in time, with a plowing depth of 25 cm~35 cm or a deep loosening of 40 cm~50 cm; before sowing, perform rotary tillage and harrowing to achieve fine soil clods, leveled field surfaces, and compacted upper layers with loose lower layers. 6 Sowing 6.1 Sowing Period In late April to early May, when the soil temperature at 0~5 cm is stable above 12℃, sowing can be carried out. 6.2 Intercropping Ratio Lightly saline-alkaline soils: The row ratio of sorghum to sesbania is 3:2, with a sorghum-sorghum row spacing of 50 cm and a sorghum-sesbania row spacing of 50 cm. The sesbania-sesbania row spacing is 30 cm. Moderately saline-alkaline soils: The row ratio of sorghum to sesbania is 1:1, with a sorghum-sesbania row spacing of 30 cm. 6.3 Sowing Us
