摘要： Based on the nutritional characteristics of fresh corn and the fertilizer supply characteristics of new fertilizers (controlled release fertilizer and bio-organic special fertilizer), the total amount of fertilizer applied was reduced and different new fertilizers were applied. The one-time application technology was used to explore the reduced fertilization technology of Sweet corn. The results showed that the yield of Sweet corn was not affected by using bio-organic special fertilizer and slow controlled release fertilizer. Reduce the total amount of fertilizer application by 20 %, and the yield of Sweet corn will not be affected. There is a difference in soil available nutrients between different fertilization treatments after the completion of the two planting seasons. Using the same amount of controlled release fertilizer and 20 % less dosage of controlled release fertilizer has the tendency to reduce soil NO3-N, the difference is significant. The soil available P and K in each treatment were different, but there was no regular pattern.
