Abstract

Abstract:

Zinc, as an essential trace element for plants and a component of the active centers of more than 300 enzymes in the human body, urgently needs to address the issue of its deficiency. Fresh edible corn, with a wide consumer base, strong zinc accumulation capacity and high economic value, serves as an ideal crop for zinc nutritional biofortification. This study systematically reviews the current technical pathways and development prospects of zinc nutritional enhancement in fresh edible corn, and points out that future research should focus on the controlled-release application of nano-zinc fertilizers and the targeted breeding of varieties with efficient synergistic accumulation of multiple nutrients. Meanwhile, market expansion should be achieved by extending the industrial chain and promoting branded marketing, so as to realize the sustainable development goal of “high yield, high zinc content and low risk”. The studies demonstrate that establishing a full-chain innovation system from technological research and development to industrial transformation is the core key to breaking through the industrialization technologies of zinc-biofortified crops.

Key words: zinc biofortification, fresh corn, biofortification technology, precision fertilization, policy support
