种衣剂技术现状与展望OA

Seed coating technology,as the core means of seed treatment,plays an irreplaceable role in improving seed quality,ensuring uniform emergence of crops,and resisting biological and non-biological stresses.However,the environmental residues and ecological risks of traditional chemical seed coating agents have become increasingly prominent,while the research on biological and intelligent seed coating agents lags behind,and the stability of coating effects in complex field environments is poor,which has become a key bottleneck for the sustainable development of this field.From the perspective of"composition-mechanism-application-trend",a systematic analysis is conducted on the active ingredients,film-forming substances,and solid carriers of seed coating agents,as well as their synergistic action mechanisms;the process characteristics and application scopes of three mainstream technologies,namely film coating,seed encapsulation,and seed pelletization,are elaborated;the action mechanisms of seed coating agents in inhibiting bacteria and pests,promoting growth,and enhancing stress resistance are deeply analyzed;the field application effects of these agents in major food crops such as rice,corn,and wheat,and economic crops are systematically reviewed;in response to the core issues faced by the current seed coating agent industry,such as environmental safety risks,single functions,and insufficient intelligence,a technical development path centered on"high efficiency and low toxicity,biological functionalization,and intelligent response"is proposed.Three dimensions of material research,controlled-release carriers,and scenario application are focused on to achieve collaborative breakthroughs,aiming to provide theoretical references for promoting the green transformation of seed coating technology and agricultural sustainable development.
