Abstract: Celery is widely favored by the public for its rich nutrients,crisp texture,and unique aroma.
However,celery is extremely sensitive to water conditions. Micro-irrigation,as an emerging irrigation technology,has gradually become an important tool for promoting the sustainable development of modern agriculture. At present,there is limited research on the impact of micro-irrigation layout methods on the growth and quality of celery. In this study,we aimed to explore the effects of different moistube burying depths ( 10cm and 20cm ) and laying densities of micro-irrigation belts on the growth,leaf SPAD,yield, quality,mineral element content,irigation water use eficiency,and pesticide residues of celery. The results showed that under the conditions of a buried depth of 10cm and a layout of 3 pipes in 2 rows,celery plants exhibited the optimal performance in growth indicators such as plant height,stem diameter, petiole length,width,and tillr number. Micro-irrigation significantly increased the content of vitamin C,essential oils,calcium,and magnesium in celery,and reduced the crude fiber content. However,with the increase of laying density,water use efficiency decreased. The study also found that micro-irrigation significantly reduced the residues of chlorothalonil and cypermethrin. Taking into acount of growth performance,nutritional quality and water use efficiency, this study found that a buried depth of 10cm and a layout of 3 pipes in 2 rows is an efective method for optimizing celery cultivation. It can improve the growth performance and quality of celery,while enhance the water resource utilization efficiency.
