This paper introduced the integrated drip irrigation and fertigation technology for wheat in Anyang City, Henan Province, from the aspects of variety selection, fine land preparation, drip irrigation equipment installation and layout, as well as scientific sowing. In production, semi-winter wheat varieties with water-saving, drought-tolerant, high and stable yield, and mechanical harvesting suitability are recommended, such as Anmai 1350. Fields with loose soil and strong water and nutrient retention capacity are selected for rotary tillage and land preparation. Drip irrigation systems (main hub and water pipeline network) are laid parallel to the planting direction using shallow burial or surface layout. Sowing should be carried out timely from October 5 to 25 when the relative soil moisture content in the plow layer is no less than 70%, with a sowing depth of 3–5 cm and a seeding rate of 8–15 kg/666.7 m². The integrated water and fertilizer management of wheat should follow the principle of “small amount and frequent application with balanced nutrition”. Water and fertilizer management for overwintering should be implemented in early December based on seedling investigation. No topdressing is required for class-Ⅰ seedlings, while urea at 3–4 kg/666.7 m² should be applied with overwintering irrigation for class-Ⅱ and class-Ⅲ seedlings. From the regreening and jointing stage to the filling stage, appropriate irrigation volume should be applied according to soil moisture content at different growth stages, combined with split topdressing of urea and potassium fertilizer. Meanwhile, maintenance of irrigation equipment should be performed, including filter cleaning and pipeline inspection. Weed control is conducted using 30 g/L mesosulfuron-methyl OD and 20% fluroxypyr EC, etc. Diseases and pests such as sharp eyespot and aphids are controlled with 20% imidacloprid WP and 5% abamectin SC, etc. Harvesting is performed from late wax maturity to early full maturity when the grain moisture content is below 13%. This study offers technical references for integrated drip irrigation and fertigation in wheat cultivation for similar regions.
