轮作能够显著改良土壤的理化性质,提高作物的产量和品质,降低病虫害的发生。基于此,主要对蔬菜轮作进行了深入的研究,探讨蔬菜轮作的主要原则,适宜轮作的蔬菜种类,以期为蔬菜轮作研究提供理论基础和技术指导。在同一块土地上,如果长期进行连作种植,将会导致蔬菜作物的病虫害加剧,土壤的理化性质发生改变,土壤变得盐渍化或酸化,严影响作物的产量和品质。制定合理的轮作制度,显著提高作物的产量和品质,改善土 Rotation can significantly improve the physical and chemical properties of soil, improve crop yield and quality, reduce the occurrence of pests and diseases. Based on this, the paper mainly studied the rotation of vegetables and discussed the main principles of vegetable rotation and the types of vegetables suitable for rotation, in order to provide the theoretical basis and technical guidance for the research of vegetable rotation. Long-term continuous cropping on the same land will result in aggravation of pests and diseases of vegetable crops, changes in the physical and chemical properties of the soil, salinization or acidification of the soil, and serious impact on crop yield and quality. Formulate a reasonable rotation system, significantly improve crop yield and quality, improve the soil
