作物自毒作用及防控研究进展
首发时间:2018-10-19
摘要:在现代农业当中作物重茬种植产生自毒物质导致连作障碍的现象很普遍,严重危害着农作物正常生长发育。合成自毒物质有酚酸类化合物、香豆素、生物碱、萜类化合物、非蛋白氨基酸类似物、酶类等以及作物根系的次生代谢物和一些分解产物。本综述主要阐述自毒物质的产生的原因、自毒物质对作物的影响以及相应的防控措施,为今后更深入研究连作障碍提供一些有价值的参考。

Advances in research on crop self-toxicity and prevention and control
Abstract:In modern agriculture, crops are planted with heavy toxic substances, which lead to continuous cropping obstacles, which seriously endanger the normal growth and development of crops. Synthetic self-toxic substances include phenolic acids, coumarins, alkaloids, terpenoids, non-protein amino acid analogs, enzymes, etc., as well as secondary metabolites and some decomposition products of crop roots. This review mainly describes the causes of the production of self-toxic substances, the impact of self-toxic substances on crops and the corresponding prevention and control measures, which provide some valuable references for further study of continuous cropping obstacles in the future.
Keywords: autotoxicity cause impact crop prevention and control measures
