Celery and vegetable three-dimensional relay intercropping technology

The invention discloses a celery and vegetable three-dimensional relay intercropping technology. The technology comprises the following steps of firstly, selecting proper celery and vegetable seeds, then carrying out soil preparation and fertilization, applying fully decomposed organic fertilizer, ternary compound fertilizer and boric fertilizer per mu, performing bedding after turning over, fineharrowing and flattening of the land, sufficiently watering the land before sowing, then uniformly sowing vegetable seeds and celery seeds, and after the seeds are sown, carrying out micro-spraying watering on the planting land until the land is thoroughly watered and bedding surfaces are wet. The vegetable seeds and the celery seeds can be sown at the same time, vegetables and celery are harvested in batches through later-period management, the land is fully utilized, the vegetable yield per unit area is greatly increased, meanwhile, the winter income of farmer households is increased, and the problems that in the cu
