一种制种玉米父母本分区灌溉系统及水肥调控方法
By implementing a zoned irrigation system for male and female maize parent lines and water and fertilizer regulation methods, the problem of wasted water and fertilizer resources in seed maize production in arid and rain-scarce areas has been solved. This has enabled the classified management of male and female lines, improved seedling emergence rate and pollen grain quantity, promoted pollination, and increased seed yield and quality.

AI Technical Summary
In seed maize production in arid and low-rainfall areas, traditional irrigation and fertilization methods lead to waste of water and fertilizer resources and affect the emergence rate, uniformity, and pollen grain quantity of male and female parents, thus limiting the development of the seed maize industry.
A zoned irrigation system and water and fertilizer regulation method for parent maize seed production were adopted. Through the design of drip irrigation tape units and branch pipes, the parent and parent lines were managed separately to meet the irrigation and fertilization needs of different growth stages. This included separate irrigation of the parent line, separate irrigation of the parent line, and simultaneous overall irrigation of both parent lines, combined with optimized water and fertilizer management.
It improved the emergence rate and uniformity of both male and female parents, increased pollen grain quantity, promoted maize pollination, enhanced seed yield and quality, improved water and fertilizer use efficiency, reduced water and fertilizer input, and improved population structure.
