Abstract

Abstract: Green orange garden soil and green orange seedling were used as materials, and different soil modifiers were used to carry out pot experiment. The results showed that the application of organic fertilizer and soil modifiers could improve the pH, available nutrients and soil structure of green orange garden soil. It can also promote the growth of green orange seedlings. Through the contrast test among the treatments, it was found that the effect of organic fertilizer （2‰） + hydrated lime （1‰） and organic fertilizer （2‰） + calcium magnesium phosphate （1‰） were the best. Compared with the control, the pH of soil increased by 1.23 and 0.82, the exchangeable aluminum content of soil decreased by 97.65% and 96.86%, respectively, the percentage of soil aggregate structure increased by more than 1.52%, and the dry weight of aboveground part of green orange seedling was higher than that of the control by more than 40.09%.

Key words: soil modifiers, green orange garden, soil physical and chemical properties, growth characteristics
