Effects of Partial Substitution of Nitrogen Fertilizer by Organic Fertilizer on the Quality of Lilium lancifolium
This research was conducted in the typical lily planting area,and Lilium lancifolium was taken as the research material.Five treatments were set up in the experiment,including 100%chemical fertilizer treatment(CK),as well as 25%(T1),50%(T2),75%(T3),and 100%(T4)nitrogen fertilizer substitution by organic nitrogen,respectively.The suitable amount of self-made organic fertilizer for partial substitution of nitrogen fertilizer and the short-term effects on lily quality were discussed through the changes in bulb yield and quality indexes of lily.The results show that T1 and T2 have no significant effects on the single weight and yield of lily bulbs,while T4 significantly decreases the yield by 26.4%.There is no significant change in nitrogen and potassium content in lily bulbs,but the phosphorus content in T2 and T3 increases by 21.36%and 22.85%,respectively.In T4,the protein content decreases significantly by 16.41%,while the cellulose content increases significantly by 16.67%.With the increase in substitution amount,the starch content decreases first and then increases.There is no significant change in the content of vitamin C in lily in each treatment,and T1 has no significant effect on the total sugar content of lily bulbs,but the total sugar content significantly decreases by about 18%in T2 and T3.By taking the yield and quality into account,it is better to control the amount of organic fertilizer for substitution of nitrogen fertilizer within 25%.
