微生物种子包衣的应用与研究进展

The microbial seed coating and its application

摘要:

种子包衣是一种高效、新兴的种子处理技术。该技术将外源性材料与种子紧密结合，从而提高种子性能，最终提高作物产量和品质。植物有益微生物(plant beneficial microorganisms, PBM)是指能够促进植物养分吸收、增强其对生物和非生物胁迫的耐受力，并促进植物生长或减少农业化学投入的微生物。因此，PBM可以作为一种微生物种子包衣剂。微生物种子包衣作为一种能够显著提高作物产量、经济效益和农业系统的可持续性发展的革新性技术，因其生态安全性和社会经济效益被认为是传统农业技术有前途的替代品。本文综述了微生物种子包衣技术及其在作物生产中的应用，并对其局限性和不一致性进行讨论。

Abstract:

Seed coating is an efficient seed treatment technology, which combines exogenous materials with seeds to improve seed performance and further crop yield and quality. Plant beneficial microorganisms (PBM) refer to the microorganisms that can promote plant nutrient absorption, enhance its tolerance to biotic and abiotic stresses, promote plant growth or reduce the agricultural chemical input. Therefore, PBM can be used as a microbial seed coating agent. As an innovative technology, microbial seed coating can significantly improve crop yield and its economic benefits, and maintain sustainable development of the agricultural system, which was thought to be a promising alternative to conventional agricultural technology. The present paper reviewed the microbial seed coating technology and its application in crop production, and its limitation and inconsistence were also discussed.
