摘 要
本文探讨了设施蔬菜连作障碍的现状和挑战，指出其对蔬菜产业稳定性的威胁。连作障碍主要由土壤结构破坏、病原菌积累和不当栽培管理引起。土壤养分失衡和物理性状恶化是主要成因。为应对这一问题，提出了科学施肥、轮作间作、调节土壤pH值和物理性状改善等措施，以恢复土壤生态，促进蔬菜优质高产，对农业效益和食品安全具有重要意义。

STUDY ON THE CAUSES AND MITIGATION MEASURES OF CONTINUOUS CROPPING OBSTACLES IN FACILITIES
ABSTRACT
This paper discusses the current situation and challenge of facility vegetable continuous cropping obstacles, and points out its threat to the stability of vegetable industry. The continuous cropping obstacles are mainly caused by soil structure destruction, accumulation of pathogens and improper cultivation management. Soil nutrient imbalance and the deterioration of physical traits are the main causes. In order to cope with this problem, measures such as scientific fertilization, crop rotation intercropping, soil pH regulation and physical character improvement are put forward, so as to restore soil ecology and promote high quality and high yield of vegetables, which is of great significance to agricultural benefits and food safety.
