摘要
植物生物刺激素是指一类用于促进植物生长发育,缓解非生物胁迫及提高作物品质的物质或微生物,主要包括腐植酸、几丁质及其衍生物、海藻提取物等。生物刺激素的出现,为农产品安全提供了新的思路和解决方法,并广泛应用于农业生产,逐渐成为化肥和农药提质增效的一大利器。本文对生物刺激素定义的发展,主要分类和功能机制,以及生物刺激素在植物营养、生长发育、抵抗非生物胁迫和改善作物品质等方面的研究现状进行了综述,对植物刺激素在农业上的应用前景进行展望,并对存在的问题进行探讨。
The plant biostimulants are diverse substances or microorganisms which include humic acid, chitin and its derivatives, seaweed extracts, etc. applied to enhance plant growth, development, tolerance to abiotic stresses and crop quality traits regardless of its nutrient content. The emergence of biostimulants has provided new ideas and solutions for the safety of agricultural products, and they have been widely used in agricultural production. They also have become a powerful tool for improving the efficiency of fertilizers and pesticides. The purpose of this review is to better under-standing of the concept of plant biostimulants including main categories and regulatory mechanisms in plants. Moreover, the characteristics of these biostimulants and its effects on plant growth,development, tolerance to abiotic stress, plant nutrition and crop quality traits are thoroughly described. In addition,this paper also briefly described the application prospects of plant biostimulants in agricultural production,opportunities and future challenges.
