蔬菜生长过程中,需要各种营养元素,缺乏其中任何一种,均会导致各种病理症状,如变色、变形、生长受阻等,从而影响蔬菜的产量和质量。在传统农业当家的时代,由于有机肥的大量使用,缺素问题并不突出。但随着生产的迅速发展,特别是农用工业技术的大量导入,随之带来了有机肥大量失用的负面,因而导致日趋严重的缺素问题,成为阻碍蔬菜优质、高产的又一新的主要 Vegetable growth process, the need for a variety of nutrients, the lack of any one, can lead to a variety of pathological symptoms, such as discoloration, deformation, growth retardation, which affect the yield and quality of vegetables. In the era of traditional farming, due to the extensive use of organic fertilizer, the problem of lack of quality is not prominent. However, with the rapid development of production, especially the introduction of a large number of agricultural industrial technologies, the consequent negative consequences of the large-scale deactivation of organic fertilizers have led to the problem of increasingly serious deficiencies and a new obstacle to the high quality and high yield of vegetables main
