A precision irrigation and fertilization device for southward migration of corn breeding

Abstract

This application provides a precision irrigation and fertilization device for maize breeding in southern China, relating to the field of water and fertilizer equipment technology. It includes an integrated water and fertilizer supply unit, a smart control host for different growth stages, a multi-zone independent drip irrigation network component, directional drippers on the ridge surface, a soil temperature and humidity sensor module, a rainfall sensor module, and a backwashing and anti-clogging module. The host pre-stores three sets of water and fertilizer programs for the maize seedling, jointing, and grain-filling stages, as well as a parallel program for intercropping. The backwashing and anti-clogging module is located between the main pipe and each zone's branch pipes. The rainfall sensor module and the soil moisture sensor module are respectively connected to the host to achieve dual-threshold linkage water control. This application has the effects of precise water and fertilizer saving according to growth stages, dual-program parallel adaptation to maize intercropping modes, dual-threshold linkage water control and flood prevention, online backwashing and anti-clogging, and improved accuracy of data from southern breeding experiments.
