Abstract: Vegetables are important economic crops. Many growers continuously grow vegetables for many years and apply excessive chemical fertilizer to pursue high yield and high income. This planting method led to serious acidification of soil and reduction of vegetable yield. In order to explore the effects of soil conditioner on improvement of vegetable yield and acidified soil, the field experiments were conducted. The results showed that the yield increasing effect of Tianji soil conditioner and calcium magnesium phosphate fertilizer on malabar spinach were 62.6% and 29.7%, respectively. After treatment with two soil conditioners, nitrogen, phosphorus and potassium in leaves increased by 13.5%~65.5%, and total amount of exchangeable acids in soil decreased by 41.9% and 16.8%, which showed a certain regulation effect on exchangeable cation content and elements contents in soil. This study analyzed the effects of applying soil conditioner on the yield of malabar spinach and soil physical and chemical properties, so as to provide reference for vegetable production.
